How does a main circuit breaker work in a home?

The two power lines that bring electricity into your home run through the service panel. Each of the main wires carries 120 volts of electricity, equaling 240 volts in total. The main breaker attaches directly to these two wires. Below the main breaker, the two wires connect to two electrically conductive bars, called hot buss bars.

How do you wire a main breaker box?

Plug in the main breaker and move it to the off position. Electrical panel boxes differ some, but there is only one way the breakers will plug in. Tilt the breaker so the notched end slips into place. Then push the breaker over the bus bar until it is secure. Notice the two ground bars on either side of the box.

How does a circuit breaker connect to a service panel?

Inside your service panel, these service wires connect directly to the main breaker, which then distributes power down through two individual hot buss bars in the service panel. The individual circuit breakers for branch circuits will receive their power by connecting to one or both of these hot buss bars.

Can a licensed electrician wire a breaker panel?
