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.
A recurring hot smell should be investigated even when breakers remain on and visible equipment still works. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
Buzzing or crackling together with a burning smell raises concern for a loose or arcing connection. If there is active fire, heavy smoke or immediate danger, move to safety and call 911 first.
