Breaker panel is mostly used at every home and is the main distribution point for electrical circuits. You might have seen a flat, grey metal panel somewhere in a garage, utility room, basement, or sometimes in a finished cabinet or an accessible closet. Breaker panel provides between 100 and 200 amps of total power, and modern homes with many electrical appliances now sometimes require as much as 300 amps. Now that you know its function, you may want to know what's inside the circuit breaker panel. The Circuit Breaker Panel Diagram will help you understand more.

1. Understanding Circuit Breaker Panel Diagram

It consists of the main disconnect switch, neutral bus bar, double-circuit breaker, and ground bus bar.

Main disconnect switch - These switches isolate the complete wiring in a building and prevent accidents. It is generally placed in an exterior box enclosure, or it may simply be the main circuit breaker on the home's main service panel.

Neutral Bus Bar allows neutral wires to be terminated in the service panel with little space. Majorly, tin-plated neutral bars are compatible with aluminum and copper wiring. The neutral circuit wires connect to the neutral bus bar and the ground wires to the grounding bar. Some circuit breakers contain a pigtail wire that attaches to the neutral bus bar.

Double Circuit Breaker - It is used to handle high volts of power in the circuit, up to 240 volts.

Ground Bus Bar - The main objective of using ground bus bars is to terminate all the white return wires from the multiple load circuits in the building.

3. Important Tips to Consider While Creating Circuit Breaker Panel Diagram
Show all insulations in the wire, if any, in the Circuit Breaker Panel Diagram.
Specify the volts that the breaker can handle in the circuit diagram.
Always make sure to have the ground and neutral bus bar in the circuit.
Show using arrows the different components in the diagram.


Power comes to your building from the utility company's lines. It then flows through an electrical meter, records your electricity usage, and then into the circuit breaker panel. Some systems also have a large disconnect switch between the meter and the panel. Hopefully, the Circuit Breaker Panel Diagram will help you understand its working in detail. It is recommended to use EdrawMax Online to create a Circuit Breaker Panel Diagram for your projects. It should be noted here that since these circuit diagrams are the blueprints of the actual working models, ensure that you use the correct symbols provided by EdrawMax Online.
