Wire — NM-B (Romex)

12/2 NM-B (20A 120V Circuits)

Estimate for 24’×40’ garage — each circuit averages 60-80 feet from panel through outlets, plus 10-15% waste for routing, mistakes, and leaving service loops at boxes.

Qty	Size	Use	Price (Apr 2026)
1	1,000’ spool 12/2 NM-B w/ground	All 120V circuits (perimeter, workbench, ceiling/door, lift bay, mechanical, UPS)	$549.00($488.61 after Menards 11% rebate)

1,000 feet covers all 11 120V circuits (~750’ needed) with ~250’ spare for mistakes, reroutes, or future additions. The 1,000’ spool is better per-foot ($0.55)thanthree250^{\prime }rolls($0.66/ft, $164/roll at Menards).

12/3 NM-B (3-Way Switch Travelers)

Qty	Size	Use	Price (Apr 2026)

Buy Wire All at Once — Menards Mt Pleasant Is the Best Deal

Wire prices fluctuate with copper markets. Buying all your wire in one trip locks in your price. As of April 2026, all three big-box stores (Home Depot, Lowe’s, Menards) list the 1,000’ 12/2 spool at $549—but\ast \ast Menard{s}^{\prime }11$488.61**, the lowest price found. Bay City Wholesale Electric quoted $597.37 for the same spool, so the supply house advantage has flipped on this product. The rebate comes as a Menards gift card, which works fine if you’re buying the rest of your electrical supplies there anyway.

Boxes

Walls are open (pre-insulation) — use new-work nail-on plastic boxes. These mount directly to studs and are much faster/cheaper than old-work boxes.

Spec all 1-gang boxes as deep (22+ cu in) across the board. Cost delta is ~$0.50-1/box($10-15 total over the project) and any outlet or switch location can later accept a Shelly Plus 1/1PM without re-boxing. 2-gang boxes (32 cu in) are already deep enough — no change needed there.

2-Gang Boxes (4-Plug Locations)

Qty	Description	Est. Price	Notes
15	2-gang new-work plastic box, 32 cu in minimum (Carlon B232A or equivalent)	~$2-3 ea	Perimeter and workbench locations — 2 duplexes per box = 4 outlets per location

1-Gang Boxes (Single Duplex Locations)

Qty	Description	Est. Price	Notes
10	1-gang deep new-work plastic box, 22+ cu in (Carlon B122A or equivalent)	~$1-2 ea	End-of-run locations, mechanical room, UPS outlets — deep spec for future Shelly-upgrade flexibility

Ceiling / Special Boxes

2026-06-03 correction — octagon boxes are wrong for the ceiling duplex positions (box fill)

Bench check during staging caught this. The 4” octagon on hand (Southwire 54151-F-UPC, 1-1/2” deep) is fine for the stairwell light fixture but over the NEC box-fill limit for the duplex ceiling outlets, which are pass-through on the daisy-chained ceiling run:

• A 1-1/2” octagon = 15.5 in³. A pass-through duplex box (12/2 in + out = 4× #12 @ 2.25 = 9.0 in³, grounds 2.25, duplex device 4.5) needs 15.75 in³ → over per NEC 314.16(B). KO-mounted connectors with the clamp outside the box (snap-in or twin-screw) add no clamp allowance per 314.16(B)(2) — so there’s nothing to spare the octagon here.
• The hole-mismatch you’ll notice on the bench (receptacle yoke doesn’t bolt to the bare box) is not the reason — octagons use 8-32 fixture-strap spacing and a duplex always mounts to a cover/mud ring, which the BOM already planned for. Fill is the deciding factor.

Resolution: the 8 ceiling duplex positions move to 4” square (1900) box, 2-1/8” deep (30.3 in³) + 1-gang 5/8”-raised mud ring (5/8” matches the Type X garage-ceiling drywall, and 2-1/8” gives headroom for the bay-lighting Shelly position). Keep 1 octagon for the stairwell fixture. Return the 5 surplus octagons and drop the planned purchase of 3 more. See bench-check photo.

Qty	Description	Est. Price	Notes
9	4” square (1900) box, metal, 2-1/8” deep, 1/2”-3/4” KO, F-bracket — Southwire 52171-FS-UPC	$5.99 ea (HD)	✅ Ordered 2026-06-03 — HD order WK27532942, 9 @ $5.99=$53.91 ($57.14 w/ tax), store pickup Mt Pleasant #2732. HD receipt. Ceiling-mounted duplex outlets — replaces the octagons per the 2026-06-03 correction above. Breakdown: 3 GDO + 2 cord reels + 3 vehicle-bay lighting = 8 needed; 9th is a spare. Pairs with a 5/8” mud ring (next row).
8	1-gang single-device mud ring, 5/8” raised, for 4” square box — OHLECTRIC galvanized, fire-rated (Raco 768 / Southwire 52C14 equivalent)	$18.99 / 4-pack (Amazon)	✅ Ordered 2026-06-03 — Amazon order 114-1258773-1525810, 2× 4-packs = 8 @ $37.98($35.51 after rewards). Amazon receipt. Provides the 6-32 device holes; 5/8” raise brings the device flush with the 5/8” Type X ceiling drywall. One per 4” square box above (8 of 9 boxes).
1	4” octagon ceiling box, metal, 1-1/2” deep, F-bracket (Southwire 54151-F-UPC)	on hand	Stairwell light fixture only (Shelly-at-load for stairwell 3-way) — octagon is the correct box here; fixture mounts directly. Already on hand from the 2026-05-24 HD trip; the other 5 octagons are being returned.

Box subtotal (120V): ~$80-125

Box Fill Check — 2-Gang Boxes (NEC 314.16)

For a 2-gang box on a single 12 AWG circuit passing through (daisy-chain):

• Hots: 2 (in + out) = 2 conductors
• Neutrals: 2 (in + out) = 2 conductors
• Grounds: all = 1 conductor
• Devices: 2 × 2 = 4 conductors
• Internal clamps: 1 conductor
• Total: 10 × 2.25 cu in = 22.5 cu in → 32 cu in box passes with room to spare

Receptacles & Devices

20A Duplex Receptacles (TR Required — NEC 406.12)

Qty	Description	Price (Apr 2026)	Notes
8	20A GFCI TR receptacle, white (Legrand radiant at Menards, or Leviton GFNT2-W)	$21.42ea($19.06 after rebate)	First outlet on each non-GFCI-breaker circuit (4 perimeter + 2 workbench + 1 lift bay + 1 UPS). All downstream outlets on that circuit are protected.
40	20A TR duplex receptacle, white (Legrand at Menards, or Leviton T5820-W)	$4.46ea($3.97 after rebate)	Standard outlets — downstream of GFCI protection
2	20A TR WR duplex receptacle (verify WR-rated option at Menards)	~$5-8 ea	Lift bay support — weather-resistant rated for grease/fluid environment near lift

Orange Receptacles (UPS Circuit — Visual Identification)

Qty	Description	Est. Price	Notes
4-6	20A TR duplex, orange (Leviton T5820-OR or Hubbell equivalent)	~$4-6 ea	UPS-powered outlets at server rack, 3D printer, workbench, future loft. Orange = “this is on battery backup” — standard commercial convention.

Cover Plates

Qty	Description	Est. Price	Notes
15	2-gang duplex wall plate, white	~$1-2 ea	For 4-plug boxes
15	1-gang duplex wall plate, white	~$0.50-1 ea	Single duplex locations
6	1-gang toggle wall plate, white	~$0.50-1 ea	Light switch locations (entry, stairwell top, loft, workbench, lift bay, soffit switch is SLS-installed)
1	2-gang toggle wall plate, white	~$1-2 ea	Stairwell bottom — vehicle bay 3-way + stairwell 3-way share this box
8	Single-duplex device cover for 4” octagon ceiling box — superseded 2026-06-03	—	Moved to the section as 8× 1-gang 5/8” mud rings paired with the new 4” square boxes (see the 2026-06-03 correction callout there). The original plan was octagon + flat duplex cover; the box-fill issue replaced the octagons with 4” square boxes, and the mud ring now serves as both the device adapter and the cover. No separate octagon duplex covers needed. (The stairwell octagon gets a light fixture mounted directly, no duplex cover.) The standard 1-gang duplex wall plates (row above) still mount over these mud rings at finish.

Receptacle subtotal (120V): ~$405-480list/$360-430 after rebate

Light Switches & Smart Relays

Switch topology per Electrical Planning: Switch Topology. Entry soffit switch already installed by SLS — not re-purchased here.

Toggle Switches

Qty	Description	Est. Price	Notes
4	20A 3-way toggle switch, white (Leviton CS320-2W or equivalent)	~$5-7 ea	2 per 3-way circuit × 2 circuits (vehicle bays + stairwell)
4	20A single-pole toggle switch, white (Leviton CS120-2W or equivalent)	~$3-5 ea	Workbench, lift bay, loft main, spare

Smart Relays — Shelly Plus Series

Install pattern: single-pole circuits → Shelly behind the switch; 3-way circuits → Shelly at the load/fixture box with conventional 3-way toggles as upstream SPDT controls. See [[Email Imports/2026-04-20 - Shelly - Wiring Reference Screenshot.png|Shelly behind-switch wiring reference]].

Qty	Model	Use	Est. Price (Apr 2026)

1	Shelly Plus 1	Exterior soffit circuit — retrofit behind the SLS-installed switch (soffit switch already exists)	~$18-22

Shelly subtotal: ~$130-165 list (Shellys don’t qualify for Menards rebate; order direct from Shelly US or Amazon)

Switch-Location Boxes (Same Deep Spec)

Since all 1-gang boxes are now spec’d deep, switch locations use the same box as outlets. Quantity below is additional boxes for switch/fixture locations beyond the outlet count.

Qty	Description	Est. Price	Notes
4	1-gang deep plastic new-work box, 22+ cu in (Carlon B122A or equivalent)	~$1-2 ea	Shelly-behind-switch locations (workbench, lift bay, loft, soffit retrofit)

Fixture-side octagons for Shelly-at-load are already counted above

The 3-way Shelly relays (vehicle bay + stairwell) live in fixture-side octagon boxes, but those are already counted in the Ceiling / Special Boxes section above (vehicle bay Shelly shares the first vehicle-bay lighting outlet; stairwell Shelly is in the stairwell fixture octagon — the 10th in that count). No extra octagons here.

Switches + relays + boxes subtotal: ~$170-220

GFCI Protection Strategy (120V)

Circuit	GFCI Method	Why
Ceiling/door (openers, cord reels)	GFCI breaker (BR120GF)	First outlet is on the ceiling — breaker avoids ladder reset
Perimeter walls (4 circuits)	GFCI first receptacle	First outlet is at accessible wall height
Workbench (2 circuits)	GFCI first receptacle	First outlet at bench height, accessible
Lift bay support	GFCI first receptacle	Accessible near lift column
Mechanical/server	Standard breaker	Dedicated equipment, not general-use receptacles (verify with AHJ)
UPS distribution	GFCI first receptacle	First outlet accessible in mechanical room

This mixed approach saves ~$200 vs. putting GFCI breakers on every circuit, with no code compliance difference. 240V circuits use 2-pole GFCI breakers — see 240V GFCI strategy.

Misc. Hardware & Supplies

Splicing — Wago 221 Lever Nuts (Primary)

Decision (2026-05-22) — Wago-Exclusive Install

Wago 221 lever nuts are the primary splice method for the entire install. Faster, more reliable on solid 12 AWG, and easier to troubleshoot than twist wire nuts. Existing inventory of twist nuts retained as backup only for stranded-wire device pigtails and tight box situations where a Wago doesn’t fit. Estimate ~175-200 splices total across the project (40 outlets × ~3 splices each + switches/lights/junctions); the workhorse SKU is the 221-413 (3-port) for daisy-chained line/neutral/ground pigtails.

Qty	Description	Est. Price	Notes
1	WAGO 221 90pc Assortment (221-2401, 221-412, 221-413, 221-415)	$48.71 (Amazon)	Variety pack — covers all box configurations
1	WAGO 221-413 box of 50 (3-port, 24-12 AWG)	$27.51 (Amazon)	Bulk pack of the workhorse SKU for outlet pigtails
existing	Twist wire nuts (yellow/red, 12 AWG sized)	—	On hand — backup for device pigtails and tight boxes

Cable Securement, Connectors, Protection

Qty	Description	Est. Price	Notes
1 box	NM-B cable staples, 1/2” (for 12/2)	$6.99	Staple within 12” of every box, every 4.5’ of run per NEC 334.30
1 pack	Stacker cable clips, 100-pack with steel nails	$32.43 (Amazon)	Multi-cable NM-B securement — one nail holds 2-4 cables at a chase, much faster than individual staples
30 (6× 5-pk)	NM-B twin-screw cable connectors, 3/8” (1/2” KO) — Halex 20511 (HD 5-pack)	$3.58 / 5-pk	✅ Ordered 2026-06-03 — HD order WK27535305, 6 @ $3.58=$21.48 ($22.77 w/ tax), pickup #2732. HD receipt. Required at every NM cable entry into a metal box (NEC 314.17(B)) — the 4” square ceiling boxes + retained stairwell octagon, one per cable. Mounts in the 1/2” KO; clamp screws are outside the box → no box-fill allowance per NEC 314.16(B)(2). One per cable (pass-through box = 2; +1 if a wall-drop leaves the box) → ~20-25 entries; 30 gives spares.
30	Self-nailing pipe stud guards 1-1/2”×3” (nail plates)	$0.53 ea	NEC 334.17 — where wire passes through studs <1.25” from face
1 roll	Electrical tape, black (Scotch Super 33+)	$5.98	(2 rolls in cart for redundancy)

Testers

Qty	Description	Est. Price	Notes
1	Cable ripper / NM-B jacket stripper	~$5-10	Makes stripping romex jacket clean and fast
1	GFCI receptacle tester (3-light + GFCI test button)	~$12-15	Tests every outlet for correct wiring, ground, and GFCI function

Misc. subtotal (120V): ~$170-220(Wago+stackerclipsadd$110 over original estimate, justified by Wago-primary decision and time savings)

Low-Voltage Chase Rough-In (Smurf Tube)

Run alongside 120V install

Pulling 3/4” ENT (smurf tube) while walls are open is dramatically cheaper than retrofitting after drywall. Tubes terminate at LV brackets (drywall-covered until needed) or at the LV control cabinet. Every tube gets a pull string left inside so future cables can be drawn through without snaking through insulation.

Planned LV runs (see Electrical Planning for design context):

Run	Count	Approx length	Source
Front PIR → LV cabinet	1	30-50 ft	Electrical Planning
LV cabinet → rear/side wall packs	4	10-20 ft ea	Electrical Planning
LV cabinet → BXS-AM curtain PIRs	2	10-20 ft ea	Same
Cat6 → loft subpanel (energy monitor)	1	30-40 ft	Electrical Planning
Opportunistic future Cat6 / sensor drops	4-6	20-30 ft ea	Speculative chases at workbench, AP, camera, TV locations
Total	~12-14 runs	~190-300 ft

Materials

Qty	Description	Price	Notes
3	3/4” × 100’ Non-Metallic ENT Conduit (smurf tube)	$60.67 ea	300 ft total — covers planned runs + speculative future-pulls
25	3/4” Snap-In Male ENT Adapter	$1.49 ea	Terminate ENT into boxes and the LV cabinet — 2 per run
6	3/4” PVC ENT Coupling	$1.19 ea	Join tube segments when a run exceeds the roll length
8	1-Gang Low Voltage PVC New Work Bracket	$3.06 ea	Open frame (no back) — for speculative Cat6/sensor drops; drywall covers until used
existing	Pull string (Southwire PL500 polyline, 500 ft, 210 lb tensile)	$13.29	Already received 2026-05-13. Pull a length into every tube as it’s run.

LV chase subtotal: ~$258

Two things to remember

1. Pull string into every tube as you install it. A smurf tube without a pull string is decoration — fishing string through a finished wall is miserable.
2. Cap both ends with tape until cable is pulled — keeps drywall mud and insulation debris out.

Home Theater — 1.25" ENT (Future)

The recessed floor box → equipment rack run for the loft home theater calls for 1.25” ENT (not 3/4”), to fit HDMI head, speaker pairs, subwoofer, and shaker amp signal cables. See Home Theater Infrastructure Rough-In. Order separately when home theater scope begins.

Tools

Applies the Buy Cheap, Upgrade When Proven philosophy, with a Klein hand-tool exception (see Apprentice Toolbelt Setup) — quality hand tools are bought once and outlast the project.

Klein/Estwing Hand Tools — Apprentice Kit (Buy Now, Phase 1)

Decision (2026-05-22) — Buy apprentice kit alongside Phase 1 materials

Purchasing the core hand-tool kit ahead of Phase 1 install to maximize payback period across the entire garage build (electrical → drywall → finish work, 6-12 months of use). Memorial Day pricing at HD captures most of the available discount; the marginal savings from waiting for Black Friday don’t justify months of using mediocre tools. Knipex upgrades preferred on pliers + diagonal cutters where price delta is ≤$30.

Tool	Recommendation	Knipex Upgrade	Est. Price
Linesman pliers, 9”	Klein D213-9NE	Knipex 09 11 240 (~+$30) ⬆️	$35/$65
Wire stripper (solid/stranded, 10-18 AWG)	Klein 11055	— (no compelling upgrade)	~$21
Diagonal cutters, 7-8”	Klein D2000-28	Knipex 70 02 180 (≈ same price) ⬆️	~$35
Non-contact voltage tester	Klein NCVT-3P / NCVT-3PR	—	~$25-30
11-in-1 multi-bit screwdriver/nut driver	Klein 32500	—	~$22-25
Hammer, 16oz curved claw, stacked-leather grip	Estwing E16C (the leather-handle model — not E3-16C, which is rubber)	—	~$30-35

Subtotal: ~$170-220Klein-only\cdot$200-260 with Knipex upgrades on pliers + diagonal cutters

Other Tools — Buy as Needed

Tool	Recommendation	Est. Price	Notes
Multimeter	Klein MM400 or Fluke 323 (if not on hand)	~$30-50	Safety-critical — cheap meters give unreliable readings on live circuits. “Am I about to get shocked?” tool.
Fish tape or glow rods	Budget first	~$15-25	Less critical with open walls; useful for ceiling/floor runs
Drill + 3/4” spade or auger bit	Existing drill + ~$5-8 for bit	—	Boring studs for wire runs
Torpedo level (9” magnetic)	Whatever’s cheap (Menards $6.99 or Harbor Freight)	~$5-10	For plumbing boxes on studs

Combined Tools subtotal: ~$200-300 (apprentice kit + Phase 1 specialty tools as needed)

Phase 1: Ceiling/Door Circuit (Garage Openers)

Start Here — Solves the Extension Cord Problem

This is the first circuit to install. Everything here comes from the lists above — this section just identifies what to pull from the pile for your first project.

Item	Qty
Eaton BR120GF (20A GFCI breaker)	1
12/2 NM-B w/ground	~100 ft (from your 1,000’ spool)
4” square (1900) boxes, 2-1/8” deep + 1-gang 5/8” mud rings	5 (3 openers + 2 cord reels) — was 4” octagon; changed 2026-06-03 for box fill, see
1-gang new-work boxes	3 (front wall outlets between doors)
20A TR duplex receptacles	9 (6 ceiling + 3 front wall)
1-gang wall plates	3
1-gang 5/8” mud rings (device adapter + cover for ceiling boxes)	5 (paired with the square boxes above)
Cable staples (1/2”)	As needed
Wire nuts or Wago connectors	As needed
Nail plates	As needed where wire passes through studs

Wiring Topology

Run 12/2 from GFCI breaker in panel → up to ceiling → across to first garage door opener box → daisy-chain through cord reel and opener boxes along ceiling → drop down to front wall outlets from nearest ceiling box. This minimizes wire and keeps the run simple through open joists.

Panel Is Energized — Life-Safety Hazard

You’ll be working in the panel to install the breaker. SLS has live circuits on the bus.

1. Turn off the main breaker before installing any new breaker
2. Verify dead with your multimeter at the bus bars
3. The main breaker de-energizes everything downstream — the feed lugs above the main remain live (they come from the house), so don’t touch those
4. Install the breaker, land your wire (black → breaker terminal, white → neutral bar, bare → ground bar)
5. Restore the main breaker

Prices Updated April 2026

Prices verified at Menards Mt Pleasant, Home Depot, and Lowe’s on 2026-04-13. Wire prices have increased significantly from original estimates due to copper market changes. The 12/2 NM-B 1,000’ spool alone is $549(was$255-300). Menards 11% mail-in rebate (good through 4/19/26) brings the effective total down ~$290-320. Rebate is a Menards merchandise credit check.

Staged Purchasing

Buy all the 12/2 NM-B and 120V components first. The 240V wire and GFCI breakers (~$1,280-1,350) are a separate trip — see 240V Shopping List.

• 4” octagon ceiling box — Got Southwire 54151-F-UPC with F-bracket ($3.58)insteadofplainSouthwireoctagon($2.56). +$1/eaupgradeforthepre-alignedmountingbracket;$6 over 6 boxes. shelf-tag photo
• NM cable staples — Got 3/4” plastic 175-pack ($10.36) as substitute for the spec’d 1/2” 250-pack (HD didn’t stock as a 250-pack). 3/4” is oversized for 12/2 NM-B — treat as supplemental; still need 1/2” from Menards.
• Klein linesman pliers — Got 8” angled-head ($35.97) instead of the BOM’s 9” straight D213-9NE. Both pro-grade; angled head useful inside boxes.
• Klein wire stripper — Got Klein-Kurve ($19.97) instead of the plain Klein 11055. Klein-Kurve includes crimping jaws — small functional upgrade.
• Toggle switches (6 SP + 6 3-way, all 15A) — Switches were missing from the printable BOM PDF (see BOM gaps below). With no quantity in hand, 6 of each were pulled as cheap insurance (~$20total).Themarkdownplancallsfor4SP+43-way;thetrip-day6+6leaves\ast \ast 2spareSP+2spare3-way\ast \ast ($6 of spare insurance). 15A vs 20A: NEC 404.14(A) permits 15A switches on 20A general-purpose lighting circuits provided they don’t control the only outlet on the circuit — compliant for the planned switch locations.

Accidental over-buys noted at HD (return candidates):

• 1-gang toggle wallplate 10-packs — bought 3 packs, plan needs 1. The cart photo confirms: 3× 10-packs were pulled, the first pack already in cart was forgotten on a second wander through the wallplate aisle. Net result: 30 toggle plates on hand, only ~6 needed. Two of the three packs (~$7.30pretax/$7.74 with tax) are good return candidates against the HD policy (return window 08/22/2026, 90 days from purchase). Alternatively, keep all three as spares for the loft and any future small projects — the absolute cost is trivial. Decision: TBD by owner.

Pending (saved carts staged, not yet purchased):

• Menards Mt Pleasant — Phase 1.5 (2026-06-02+): ~$1,500 saved cart, primarily for back-ordered ENT conduit + snap-in adapters + 28 remaining 20A TR outlets + 2 WR outlets + 15 2-gang duplex wallplates + 30 steel nail plates + 1/2” cable staples + 3/8” NM push-in connectors + 4 remaining 2-gang boxes + 2 remaining 1-gang boxes.
• HD Mt Pleasant — follow-up: BR120GF self-test GFCI breaker (contractor desk online order, not on shelf locally), 50’ 12/3 NM-B yellow (OOS), remaining Klein apprentice kit (D213-9NE 9” straight linesman, plain Klein 11055 stripper, D2000-28 diagonal cutters, NCVT-3P voltage tester, 32500 11-in-1 screwdriver, Estwing E16C hammer).

BOM PDF gaps caught on the trip

The printable BOM PDF (Garage Electrical — Bill of Materials.pdf · 29 line items · ELEC-BOM-REV-A/D · 2026-05-22) was generated from this shopping list but a number of items from this markdown didn’t make it into the PDF. Catching them here so the next BOM regeneration picks them up and so the post-trip follow-up doesn’t miss them.

#	Item	Markdown qty	Where in this doc	Status
1	Toggle switches — 4× 20A 3-way + 4× 20A SP	8 total		⚠️ Trip-day 6+6 bought as 15A insurance — 2 spare each.
2	Shelly Plus relays — 3× Plus 1PM + 3× Plus 1	6 total		📦 Owner will order from Amazon (intentional big-box exclusion — Shelly direct or Amazon is the right path). Needed before rough-in commissioning.
3	Orange UPS receptacles — Leviton T5820-OR or Hubbell	4-6		📦 Owner will order from Amazon — not stocked locally.
4	2-gang toggle wall plate (stairwell bottom — vehicle bay 3-way + stairwell 3-way share this box)	1		Source same trip as the 2-gang duplex plates (Menards).
5	4” square (1900) box, 2-1/8” deep, F-bracket + 1-gang 5/8” mud ring — all 8 ceiling duplex outlets (3 GDO + 2 cord reel + 3 vehicle-bay lighting)	✅ Ordered 2026-06-03 — 9 boxes (HD WK27532942) + 8 mud rings (Amazon 114-1258773)		Revised 2026-06-03 — supersedes the octagon plan for the duplex positions on box-fill grounds (a 1-1/2” octagon, 15.5 in³, is over the limit for a pass-through duplex needing 15.75 in³). Return 5 of the 6 on-hand octagons; keep 1 for the stairwell fixture. No longer buying 3 more octagons. Bought: Southwire 52171-FS-UPC ($5.99)+OHLECTRIC5/8"mudrings($4.75 ea). See bench-check photo.
6	Stairwell fixture octagon — keep 1 on-hand Southwire 54151-F-UPC	0 (on hand)		The single retained octagon; holds the stairwell light fixture (Shelly-at-load) directly — no duplex cover needed.
7	Cable ripper / NM-B jacket stripper	1		✅ Already on hand (owner-confirmed 2026-05-24).
8	GFCI receptacle tester (3-light + GFCI test button)	1		✅ Already on hand (owner has had one for years, owner-confirmed 2026-05-24).

Action items

When the BOM PDF is regenerated for the next trip (Phase 1.5 Menards run, or a top-up at HD), make sure the Light Switches & Smart Relays, Orange Receptacles, and Testers subsections all land in the printable. The Shelly relays can stay flagged as “DO NOT PULL — order direct” so the in-store associate doesn’t get confused, but the row should be present so the Shelly order isn’t forgotten before rough-in.

See Electrical Materials Order for detailed line items and receipt links.

Day-of Shopping Sheet — Phase 1 (Prepared 2026-05-22)

Trip complete 2026-05-23 (Hershberger's) + 2026-05-24 (HD Mt Pleasant)

The trips have run. For post-trip results see Phase 1 Procurement Actuals above — it lists totals, substitutions, and remaining follow-ups. The printable PDF used in-store (Garage Electrical — Bill of Materials.pdf) has the handwritten check-offs from the actual shop. The checkboxes in the table rows below were not back-filled — they reflect the pre-trip plan.

Print this section · hand it to the Hershberger's associate

Scope: 120V circuits only (ceiling/door, perimeter, workbench, lift bay, mechanical, UPS). 240V circuits (lift, compressor, welder, EV) are a future trip — see 240V Shopping List. Do not pick up any 10 AWG, 6 AWG, 2-pole breakers, or NEMA 6-50/14-50 receptacles this trip.

Stop sequence: Hershberger’s Hardware (Clare) → Home Depot Mt Pleasant → Menards Mt Pleasant (only if HD/Hershberger’s lacks items). Hershberger’s caters to pros and built the garage — likely to have stock when both big boxes don’t, and may match or beat big-box pricing on common items. Write Hershberger’s actual prices in the blank “Hersh.” column, then pick the best source per item before driving to Mt Pleasant.

Legend: ✅ in stock · ⏳ back-ordered (date) · ❌ out of stock · 🔄 special order · ASK = critical to ask Hershberger’s first — not same-day available at either big box · 💰 = significant savings vs. the other big box (worth a deliberate routing decision)

Three items Hershberger's may save the trip on

1. 50’ 12/3 NM-B yellow — HD: out of stock · Menards: not stocked
2. BR120GF GFCI breaker (self-test, 1-pole 20A) — HD: not on shelf in Mt Pleasant · Menards: special-order only
3. 3/4” ENT box adapter (3/4 trade size) — HD: threaded out of stock · Menards: snap-in back-ordered 06/02

If Hershberger’s has all three at reasonable prices, the rest of the trip is much simpler.

Top savings opportunities (vs. picking the wrong store)

Three line items account for ~$100 in potential savings by routing correctly:

1. 💰 GFCI duplex outlets (×8) — HD 3-pack pricing $13.96/eavs.Menards$19.28/ea → save ~$42 at HD (delivery only — order ahead)
2. 💰 3/4” ENT conduit (×3 coils) — Menards $60.67vs.HD$73.00 → save ~$37 at Menards (but back-ordered to 05/30 — defer to Phase 1.5)
3. 💰 Steel nail plates / stud guards (×30) — Menards $0.53vs.HD$1.23 → save ~$21 at Menards

Smaller wins ($5-10): 2-gang plastic boxes (Menards), TR/WR industrial outlets (Menards), ENT couplings (Menards), 4” steel octagon boxes (HD).

Pricing snapshot from saved carts on 2026-05-22. Bold = lowest price among the three. 💰 = meaningful (>$10) total-cost difference at quantities needed. Each row is one purchase decision — pick the best column.

Hand Tools — Apprentice Kit (Klein + Estwing)

Klein/Estwing hand-tool exception · Memorial Day buy

Per Apprentice Toolbelt Setup, quality hand tools are a deliberate exception to “buy cheap, upgrade when proven” — bought once, outlast the project. Memorial Day pricing at HD typically runs 10-15% off Klein bundles. Check Hershberger’s first — they’re a pro shop and likely have full Klein selection, possibly Knipex too. Knipex upgrades preferred where price delta is small (≤~$30) — harder German steel, sharper cutting edges.

✓	Item	Qty	Klein price	Knipex upgrade	Hersh.
☐	9” Linesman pliers — Klein D213-9NE / Knipex 09 11 240	1	~$35	Knipex ~$65(+$30) ⬆️	$___

☐	7-8” Diagonal cutters — Klein D2000-28 / Knipex 70 02 180	1	~$35	Knipex ~$35(\approx same$) ⬆️	$___

☐	16oz curved-claw hammer, stacked-leather grip — Estwing E16C	1	~$28-35	—	$___

Hammer model gotcha

The leather-grip hammer is Estwing E16C (or E16S for the older “smooth face” sticker). NOT the E3-16C — that one has a blue rubber “shock reduction grip” despite the very similar model number. Both are sold at HD. Double-check the package shows woven/stacked leather rings on the handle, not solid blue rubber. Alt: Estwing E20S if you’d prefer 20oz straight-claw framing style over the 16oz finish hammer.

Bundle tip: HD sometimes sells Klein D213-9NE + 11055 together as a 2-piece set (model D2139NE11055) at a small discount — worth a glance at the Klein rack.

Estimated subtotal: ~$170-220Klein-only\cdot$200-260 with Knipex upgrades on pliers + diagonal cutters

Cart Cleanup Before Friday Night

Home Depot cart (currently has checkout-blocking error):

• ❌ Remove: 50’ 12/3 NM-B yellow ($109) — out of stock at Mt Pleasant, blocks checkout
• ❌ Remove: 50’ 12/2 NM-B yellow ($69) — redundant; already have 1000’ spool
• ⚠️ Keep: 50’ 12/3 UF-B gray ($161) only as fallback if Hershberger’s doesn’t have 12/3 NM-B yellow

Menards cart:

• Place special-order intake for BRN120GFCS GFCI breaker (~1 week wait acceptable as backup if Hershberger’s lacks it)
• Leave back-ordered items in saved cart for a 06/02+ pickup run

Trip-Day Quick Reference

Stop	Goal	Time
1. Hershberger’s (Clare)	Pick up the 3 ASK items + check Klein/Knipex selection (pro shop — likely has the full apprentice kit + Estwing E16C) + anything else at competitive price	30-45 min
2. Home Depot Mt Pleasant	1000’ 12/2 spool + boxes + plates + breakers + GFCI outlets + Klein/Estwing tools not sourced at Hershberger’s + anything Hershberger’s lacked	60-90 min
3. Menards (optional)	Only if HD lacked critical items; primarily for special-order intake on GFCI breaker + nail plates (cheap there)	30 min
Skip	Drive home, start panel work Saturday afternoon	—

⛔ 240V Items — DO NOT BUY THIS TRIP
