Ground Floor 240V Electrical Shopping List
Scope: 240V circuits only
This document covers the 240V install — 2-post lift, air compressor, welder/plasma, and EV/auxiliary outlet. These are deferred from Phase 1 (120V rough-in) and bought as a separate trip closer to install date.
For 120V circuits (perimeter, workbench, ceiling/door, lift bay convenience outlets, lighting, LV chase) see Electrical Shopping List — 120V Install.
Future Trip — Verify Specs Before Buying
240V receptacle choice depends on the actual equipment plug. Verify NEMA configurations against the equipment manual for your specific lift, compressor, welder, and EVSE before purchasing receptacles. The list below uses the most common configurations for the planned equipment classes; the wrong receptacle is a costly mistake.
Breakers — Eaton BR Series (240V, 2-Pole GFCI)
Must match the installed 200A Eaton BR panel.
| Qty | Part | Description | Price (Apr 2026) | Notes |
|---|---|---|---|---|
| 1 | BR230GF | 30A 2-pole GFCI | TBD — verify at store | 2-post lift — NEC 2023 requires GFCI on 240V garage receptacles |
| 1 | BR230GF | 30A 2-pole GFCI | TBD | Air compressor |
| 1 | BR250GF | 50A 2-pole GFCI | 127.36 after rebate) | Welder/plasma (NEMA 6-50) |
| 1 | BR250GF | 50A 2-pole GFCI | 127.36 after rebate) | EV/auxiliary (NEMA 14-50) |
240V breaker subtotal: ~$350-400 estimated (30A GFCI price TBD)
NEC 2023 — 240V GFCI Is New
NEC 2023 210.8(A) expanded GFCI requirements to cover all 125V through 250V receptacles up to 50A in garages. This means every 240V outlet (lift, compressor, welder, EV) needs GFCI protection. The 2-pole GFCI breakers are expensive (~180. But if buying new, buy for 2023 since you’ll pass any future re-inspection.
Wire — NM-B (Romex)
| Qty | Size | Use | Price (Apr 2026) |
|---|---|---|---|
| 50’ | 10/3 NM-B w/ground | 2-post lift (30A 240V, 4-wire for local disconnect) | 155.75 after rebate) |
| 50’ | 10/2 NM-B w/ground | Air compressor (30A 240V) | 142.40 after rebate) |
| 50’ | 6/3 NM-B w/ground | Welder/plasma (50A 240V) | 239.41 after rebate) |
| 50’ | 6/3 NM-B w/ground | EV/auxiliary (50A 240V) | 239.41 after rebate) |
240V wire subtotal: ~777 after Menards 11% rebate
Buy Wire All at Once
Wire prices fluctuate with copper markets — buying all 240V wire in one trip locks in your price. The Menards 11% mail-in rebate makes the same physical product ~$96 cheaper than HD/Lowe’s on the 240V wire alone.
Boxes — 240V Outlet Locations
| Qty | Description | Est. Price | Notes |
|---|---|---|---|
| 4 | 4-11/16” square metal box + single-gang mud ring (deep, 42 cu in+) | ~$5-7 ea | Lift, compressor, welder, EV — larger box handles thicker wire |
Box subtotal (240V): ~$20-30
Receptacles & Cover Plates
240V Receptacles
| Qty | Description | Est. Price | Notes |
|---|---|---|---|
| 1 | NEMA 6-50R receptacle, 50A 250V | ~$12-15 | Welder/plasma outlet |
| 1 | NEMA 14-50R receptacle, 50A 125/250V | ~$12-15 | EV/auxiliary outlet |
| 2 | NEMA 6-30R receptacle, 30A 250V | ~$10-12 ea | Lift and compressor (verify lift plug type against your specific lift manual — some use NEMA 6-30, some 6-20) |
Cover Plates
| Qty | Description | Est. Price | Notes |
|---|---|---|---|
| 4 | Single-gang 240V flush plate (for NEMA 6-50, 14-50, 6-30) | ~$2-3 ea | 240V outlet covers |
Receptacle subtotal (240V): ~$50-65
GFCI Protection Strategy (240V)
| Circuit | GFCI Method | Why |
|---|---|---|
| 2-post lift (30A 240V) | GFCI breaker (BR230GF) | No GFCI receptacle option for NEMA 6-30 |
| Air compressor (30A 240V) | GFCI breaker (BR230GF) | Same |
| Welder/plasma (50A 240V) | GFCI breaker (BR250GF) | No GFCI receptacle option for NEMA 6-50 |
| EV/auxiliary (50A 240V) | GFCI breaker (BR250GF) | No GFCI receptacle option for NEMA 14-50 |
All 240V circuits use 2-pole GFCI breakers because there’s no GFCI receptacle made for these connector types. 120V GFCI strategy is mixed (breaker vs first-receptacle) — see 120V GFCI strategy.
Misc. Hardware
Most install hardware already bought with Phase 1
Wago 221 lever nuts, cable stacker clips, NM connectors, electrical tape, nail plates, and testers were all purchased during the Phase 1 120V install. The only 240V-specific additions are heavier staples and the lift disconnect.
| Qty | Description | Est. Price | Notes |
|---|---|---|---|
| 1 box | NM-B cable staples, 3/4” (for 10/3 and heavier) | $9.61 | Larger staples for heavier wire — 1/2” staples used for 12/2 won’t fit 6/3 |
| 1 | Disconnect switch, 30A 240V fused or non-fused | ~$15-25 | Lift local disconnect — required within sight of equipment |
Misc. subtotal (240V): ~$25-35

Wait Until Lift/Welder/EV Are On Hand
Each 240V circuit serves a specific piece of equipment. Wait to buy the matching receptacle until you have the equipment in hand and can verify the plug type from the manual or the actual cord. Wire and breakers can be bought ahead since they’re equipment-independent — but receptacles are the part that bites if you guess wrong.
Day-of Shopping Sheet (to be prepared closer to install)
This doc currently has the planning BOM. When 240V install is imminent, prepare a comparison table mirroring the Phase 1 Day-of Sheet format — verify current prices, stock status, and which store wins each line item.
Suppliers to check (same as Phase 1):
- Hershberger’s Hardware (Clare) — pro shop, often beats big-box on common items
- Home Depot Mt Pleasant
- Menards Mt Pleasant (11% mail-in rebate when active)
- Bay City Wholesale Electric — supply house quote for wire if copper prices spike
