The seven components of the electrical panel are a main breaker, branch breakers, ground bar, bonding bar, neutral bar, protective relays, and bus bars.
The main breaker is usually located near the top of the panel and serves as the means of controlling the entirety of the power within the box. This breaker is designed to trip when overloads occur to protect the building from electrical damage or fire.
Branch breakers are installed within the panel in rows and are controlled by the main breaker. Their purpose is to distribute and control the power from the main to secondary circuits.
The ground bar is a vertical metal bar that has multiple screw terminals for the grounding wires to attach. The ground wire serves to provide a direct path for any stray electric current to travel to the ground.
A bonding bar is also provided for the purpose of providing continuity for bonding conductors. Bonding conductors are mostly used to join the ground wires and neutral wiring to the building frame and other large metal parts such as pipes.
The neutral bar is the terminal bar in which the neutral conductor is connected. This is typically identified by the white wires coming in from the service entrance.
Protective relays are designed to detect flaws or wiring issues, such as a short circuit. These relays are also used to reduce the wattage in order to safely provide electricity.
Finally, the bus bars serve as a means of providing power to the branch breakers, relays, and other various components. The bus bars are constructed of an insulated copper bar and are connected to the main and branch breakers.
