Heat, burning odors or discoloration

Unusual heat, burning smells, scorch marks or discoloration around electrical equipment can indicate a serious issue. Avoid continued use and seek qualified help.

Sparking, buzzing or repeated trips

Persistent buzzing, visible sparking or breakers that repeatedly trip should be investigated rather than repeatedly reset or ignored.

Loose or damaged devices

Broken covers, loose receptacles, damaged cords and exposed components can create hazards. Keep people away from unsafe equipment until it can be addressed.

What to document

Tell the electrician when the symptom occurs, which devices or circuits are involved, and whether anything recently changed. Do not remove panel covers or expose energized components to investigate.
