Circuit Breakers

Circuit breakers are an essential component of any electrical system, protecting against power surges, short circuits, and other electrical hazards. They are also designed to trip when the electrical current exceeds a certain level, preventing damage to the electrical system. The breaker should be able to handle the amount of electrical current that flows through your system, so it's important to choose a breaker that is appropriately sized. A breaker that is too small won't be able to protect your electrical system, while a breaker that is too large will be more expensive and difficult to install.
