A panel board (also known as a distribution board, breaker panel, or consumer unit) is a metal enclosure that receives main utility power and divides it into smaller branch circuits for safe distribution to electrical devices. It houses circuit breakers or fuses to protect circuits from overloads and short circuits
Key Usage Examples of Panel Boards:
-
- Residential: Managing electricity safely in homes, typically found in utility rooms, basements, or garages.
- Commercial: Distributing power to lighting systems, HVAC units, and offices.
- Industrial: Controlling and protecting high-voltage machinery and equipment in manufacturing plants.
- Lighting Control: Specifically designed boards used to manage large lighting circuits.
- Sub-panels: Used to extend capacity to specific areas like garages or separate floors
Synonyms and Related Terms:
- Distribution Board
- Breaker Panel
- Electric Panel
- DB Box (Distribution Board Box)
- Load Center
- Consumer Unit
- MCB Panel (Miniature Circuit Breaker Panel)
Main Components & Features:
- Main Breaker/Lug: Controls the power supply to the entire panel.
- Busbars: Metal bars that transfer power to branch circuits.
- Circuit Breakers/Fuses: Protective devices that cut power during faults.
- Neutral and Ground Bars: Terminals for wire management and safety
Panel boards are essential for maintenance, allowing the safe shutdown of specific circuits without cutting power to the entire building
