Garage Eaton Panel — Main Lugs & Existing Branch Breakers Detail

Close-up of the bottom of the garage Eaton panel — large blue-labeled CSR 200A main breaker at center; four populated branch breaker positions above (SLS-installed circuits); main feeder cables routed into the lugs; two 1" conduit knockouts at the bottom for low-voltage runs

  • Date: May 25, 2026
  • Time: 6:53 PM EDT
  • Phase: Phase 1 — 120V rough-in (DIY)
  • Location: Garage SE corner — Eaton 200A panel, dead-front removed
  • Subject: Closer view of the main breaker, lugs, and the four SLS-installed branch circuits

Description

Closer view of the lower portion of the same Eaton 200A panel — the CSR 200 main breaker at center with feeder lugs above and below, the four SLS-installed branch breakers in the populated positions, and the two 1” low-voltage conduit knockouts at the bottom that already carry the SLS-pulled Cat6 and pull-string (per Cat6 milestone).

The main breaker is always sized 200A to match the panel and the 200A subfeed from the house — the actual usable capacity is limited by the 100A breaker in the house panel feeding this subpanel (per Electrical Planning § Subpanel Sizing).

Visible Elements

  • CSR 200 (Cutler-Hammer/Eaton) main breaker at center — blue product label visible; large dual-pole device with feeder lugs
  • Four populated branch breaker positions above the main — SLS-installed circuits (interior GFCI, exterior GFCI, soffit lights, generator inlet)
  • Black/white striped wire (left edge) — service-entry neutral
  • Red and black 4 AWG feeders (top of frame partially visible) — the underground subfeed conductors landing on the main breaker line-side lugs
  • Two 1” PVC conduit nipples at panel bottom — low-voltage runs (Cat6 + pull string) that come up through the slab to the network rack location
  • Eaton informational labels at top edges of frame — panel ratings and breaker compatibility chart
  • OSB sheathing behind the panel (drywall pending)

Why This Photo

Records the exact factory configuration of the main breaker and lug arrangement, useful for any future panel work (adding the 240V appliance circuits, the 2-post lift breaker, the welder receptacle, etc.). The CSR 200 main breaker accepts both BR-series and CH-series branch breakers — see Electrical Shopping List — 120V for the rationale on choosing BR for cost and the noted exception that the BR120GF (GFCI single-pole) is the breaker style used on the perimeter circuits added today.
