 · Locate the panel's circuit directory on the inside of the panel door. Determine the circuit breaker location (or "circuit number") and write a description of the circuit (load type such as "refrigerator" or a location such as "living room") in the space provided. Be sure to edit the directory if any circuits were moved to install the new circuit. Safety switches are often confused with circuit breakers and fuses, but they perform different tasks. Safety switches monitor the flow of electricity through a circuit and turn off the power in a fraction of a second if a leakage of current is detected. Safety switches provide personal protection against electric shock. Circuit breakers protect an electrical circuit by quickly cutting power ...

A printed circuit board (PCB) is an electronic circuit used in devices to provide mechanical support and a pathway to its electronic components. It is made by combining different sheets of non-conductive material, such as fiberglass or plastic, that easily holds copper circuitry. Simply, a circuit breaker is a switch that automatically interrupts electrical flow in a circuit in case of an overload or short. This guide walks you through different types of circuit breakers to help you choose which is best for your home’s electrical needs.
