Arc Fault Circuit Interrupter (AFCI) and Ground Fault Circuit Interrupter (GFCI) are two different types of circuit breakers that have different functions and uses and cannot be used interchangeably. Here are the differences between them:AFCI (Arc Fault Circuit Breaker) Design purpose:AFCI is primarily used to detect and prevent arc failure, which is an electrical failure due to loose wires or connections that can cause a fire. An arc failure usually occurs when the insulation of a wire is damag

There is indeed a correlation between the size of the circuit breaker (which usually refers to its rated current, which is the number of amps) and its strength (which is its ability to protect). The size selection of the circuit breaker should be based on the specifications of the wires in the circuit and the expected maximum load current. Here's a detailed explanation:The relationship between circuit breaker size and strengthProtection abilityThe size (rated current) of the circuit breaker dete

FuseFeatureThe fuse is a simple and effective circuit protection element. When the current flow in the circuit is large, the melt in the fuse (such as the fuse) will be blown due to overheating, thus cutting off the circuit and preventing the equipment in the circuit from being damaged due to overcurrent. In the use of AC power, it can protect various electrical equipment, lines, etc. connected to the AC power supply. For example, in the home circuit, if a short circuit fault occurs in an electr
