How often should I inspect breakers & panel?
Inspect breakers & panel at the manufacturer or authority interval, after severe weather or unusual operation, and whenever a documented condition changes.
What this means
Breakers & panel covers trips, buzzing, heat, labels, and lost circuits. Relevant observations include Same breaker keeps tripping, Breaker will not stay reset, Panel is buzzing, Panel or breaker feels hot, Water is near the panel. The correct response depends on age, design, climate, usage, installation, recent work, and the exact manufacturer instructions; these observations narrow next steps but do not prove a failed part.
Safe checks
- Use the exact manual, warranty, local authority, and service history to set the interval for breakers & panel.
- Add a check after severe weather, renovation, long vacancy, or unusual operation.
- Shorten the interval when a condition is changing or has recurred.
Stop and get help if
- Stop for heat, buzzing, arcing, smoke, burning odour, water exposure, damage, or repeated tripping.
- Never remove a cover, work live, or stand in water to reach electrical equipment.
