200 Amp Panels: The Backbone of Your Electrical Power Supply

200 amp panel

One key component in a building or home is the electrical panel, which is responsible for distributing electricity throughout. If you've ever wondered what a 200 amp panel is, you're in the right place. In this post, I will go over what a 200 amp panel is, why it is important, and everything on how to know if you really do need one.

What is an Electrical Panel?

An electrical panel, also known as a breaker box or distribution board, is a metal box that contains circuit breakers. These breakers are designed to trip and cut off the flow of electricity when an overload or short circuit occurs, preventing damage to your electrical system or appliances. The panel receives electricity from the utility company or generator and distributes it to the various circuits in your building.

Understanding Amperage

Amperage, also known as "amps," is a unit of measurement that describes the amount of electrical current flowing through a circuit. The higher the amperage, the more electrical current the circuit can handle. A 200 amp panel is designed to handle up to 200 amps of electrical current.
