What is a 15 amp fuse for?

A 15 amp fuse is designed to protect electrical circuits by interrupting the flow of electricity when the current exceeds 15 amps. This prevents overheating and potential damage to appliances or wiring due to overloads or short circuits. Commonly found in household electrical systems, it ensures safety by preventing fires and electrical hazards. It's important to replace a blown fuse with one of the same rating to maintain proper protection.
