Electrical Panel Installation

Electrical panel installation involves setting up the main distribution point for electrical circuits in a building. Also known as a breaker panel, distribution board, or fuse box, this panel receives power from the utility supply and distributes it safely to various parts of a home or building.

What Electrical Panel Installation Includes:

  1. Planning & Load Assessment:
    • Determine the total electrical load (in amps) needed for the building.
    • Decide on panel size (e.g., 100A, 200A) and number of circuits.
  2. Selecting the Location:
    • Installed in an accessible, dry, and safe location (often a utility room, basement, or garage).
    • Must meet local code requirements (clearance space, height, etc.).
  3. Mounting the Panel:
    • The metal panel box is securely fastened to a wall or support structure.
    • Knockouts are removed for incoming wires and conduits.
  4. Connecting the Main Power Supply:
    • Power from the utility (via meter) enters the panel through a main breaker.
    • This main breaker controls power to the entire panel.
  5. Installing Circuit Breakers:
    • Individual circuit breakers are installed to control specific circuits (e.g., lighting, outlets, appliances).
    • Each breaker is connected to a hot bus bar and a neutral bar.
  6. Wiring the Circuits:
    • Wires (live, neutral, and ground) are neatly routed into the panel from different circuits throughout the building.
    • Each circuit is connected to its corresponding breaker and grounding bar.
  7. Grounding & Bonding:
    • A grounding system is connected to the panel to ensure fault currents are safely discharged.
    • Bonding ensures all metal components are at the same electrical potential for safety.
  8. Labeling:
    • Each breaker is clearly labeled to identify what it controls (e.g., "Kitchen Outlets", "AC Unit").
  9. Testing and Inspection:
    • All connections are checked and tested for safety.
    • A licensed electrician or inspector verifies compliance with National Electrical Code (NEC) or local codes.

Why Proper Panel Installation Is Critical:

  • Prevents overloads, short circuits, and fires
  • Provides organized control over electrical circuits
  • Ensures safe expansion of circuits in the future
  • Required for code compliance and home resale
