Heat or smoke near outlets, switches, wiring or the electrical panel.
Smoke emerging from an outlet, switch or panel indicates heat where energized parts may still be present. If there is active fire, heavy smoke or immediate danger, move to safety and call 911 first.
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.
Turning off one device may not remove the hazard when damaged wiring remains energized inside a wall or box. If the correct breaker can be reached safely, switch it off and leave the damaged equipment untouched.
