Heat or smoke near outlets, switches, wiring or the electrical panel.
Electrical odors can travel through wall cavities, making the strongest-smelling room different from the source. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
Discoloration around a receptacle or switch can show that overheating began before smoke became visible. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
A recurring hot smell should be investigated even when breakers remain on and visible equipment still works. If there is active fire, heavy smoke or immediate danger, move to safety and call 911 first.
