Electrical connections can overheat even with normal current due to resistance, loose terminals, and oxidation. Learn how to detect and prevent failures early.

This enclosure houses the circuit breakers designed to interrupt current flow when a fault or overload occurs, protecting the entire wiring system. When they start tripping, overheating, or making strange noises, it's more than just an inconvenience - it's your home's cry for help.
