What is 100 amp fuse?

A 100 amp fuse is a safety device used in electrical systems to protect circuits from overloads by breaking the circuit when the current exceeds 100 amps. It is designed to prevent damage to wiring and equipment by interrupting the flow of electricity in the event of a fault. Commonly found in residential and commercial electrical panels, this fuse ensures that the electrical system operates safely within its rated capacity. When the fuse blows, it must be replaced to restore power to the circuit.
