Panel Label & Legend

Electrical Panel Legend and Breaker Identification

Close-up of the load center’s factory data label and the homeowner-created circuit legend. This provides the technical specifications and breaker layout necessary for planning a feeder tap to the new garage service subpanel.

Key Details Captured

  • Manufacturer label lists catalog number, maximum breaker size, bus rating, torque values, and optional breaker combinations.
  • Diagram showing panel architecture (main lugs, branch slots, neutral/ground bar arrangement) to confirm compatibility with proposed 100A feeder breaker.
  • Circuit legend handwritten on insert strips identifies existing loads (dryer, washer, water heater, furnace, A/C, etc.), useful for load calculations.
  • Shows the top-left blank breaker space where a two-pole breaker can be added for the garage feeder.

Planning Relevance

  • Confirms bus rating and breaker types supported, ensuring correct selection of 2-pole breaker and conductors for garage tie-in.
  • Provides proof of labeling compliance for inspectors during future rough-in or final inspections.
  • Serves as quick reference when coordinating with electrician or utility about panel capacity and layout.
