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:
- 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.
- 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.).
- Mounting the Panel:
- The metal panel box is securely fastened to a wall or support structure.
- Knockouts are removed for incoming wires and conduits.
- 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.
- 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.
- 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.
- 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.
- Labeling:
- Each breaker is clearly labeled to identify what it controls (e.g., "Kitchen Outlets", "AC Unit").
- 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
