Circuit Breaker Wiring Diagrams

Wiring a GFCI Circuit Breaker. This diagram illustrates wiring for a circuit breaker with a built-in ground fault circuit interrupter or gfci. This 20 amp, 120 volt breaker is a form of gfci that can be installed at the circuit source. This kind of circuit is used for dishwashers, whirlpool spas, and other locations where water contact is likely.

Inside the covering, you'll find a copper wire (the ground wire), a white covered wire (the neutral wire), a black wire (the hot wire), and a red wire (another hot wire). In the sub-panel box, the neutral and ground wires will connect the same as they do in the main breaker box, but the red and black wires will connect to the hot bar instead of a circuit breaker.

Plenty of excess wire is pulled into the panel to allow for connections to be made anywhere in the box. The electrician now bends the two black service wires for easy installation to the main breaker. In most panels, the main breaker is a large 240-volt circuit breaker that is located at the top of the panel.

Every non-engine wire (EVERY ONE) should be circuit protected with a fuse or circuit breaker. Batteries have a positive and negative. For current to flow (which does the work) a complete circuit must be made from positive back to the negative.

Each time the electrical code is revised, old wiring is “grandfathered,” on the assumption it was installed correctly. Code only requires you to update wiring in rooms being gut-renovated. To help you assess the state of your own electrical system, we’ve asked Gallant to identify the 10 most common wiring problems he sees, the dangers they pose, and his recommended solutions.
