To upgrade a breaker box, you would need to hire a licensed electrician to assess your current setup, determine the necessary upgrades based on your electrical needs, obtain the required permits, and then safely install the new breaker box with updated circuit breakers. Upgrading a breaker box involves working with high-voltage electricity, so it is crucial to leave this task to professionals to ensure safety and compliance with building codes.

Answer 3

The input side of the breaker box is the power from your electric supplier and comes through a meter so they can bill you. A qualified electrician is required to make the connection between the meter and the box. The box is also grounded to a ground rod installed at the entry point of the power.

Inside the box there are typically two bus-bars each supplying 120 VAC to a breaker. There is 240 VAC across the two bus-bars. To wire circuits to each breaker, the black wire goes to the breaker, the white wire goes to a neutral bus and the bare ground wire goes to the earth bus. There should also be a screw to "bond" the neutral and ground buses to each other.

Feed-throughs are used for any wire connected to the box by punching-out the round knock-outs in the box.

The box should be wired neatly so it is easy to trace the wires when looking inside the box.

WARNING - Dangerous voltages are present when the box is live and you should not attempt any work inside the box unless you are qualified to do so.

Unless you are an electrician, you don't even attempt it. If you are an electrician, why are you asking the question? Doing it yourself can be a quick way to die.
