Signs Your Electrical Panel Needs Assessment
Some panel problems are easy to see or hear. Others show up as symptoms elsewhere in the building. Signs that may point to a panel issue include a breaker that will not stay on or will not reset, buzzing or crackling from the panel, a panel door or cover that feels warm, scorch marks or a burning smell, and breakers that trip when the circuit is not heavily used.
A tripping breaker does not automatically mean the panel is faulty. Breakers are designed to trip when a circuit is overloaded or has a fault, so the cause may be in the wiring or an appliance rather than the panel itself.
If you notice heat, smoke, sparking or a burning smell at the panel, keep people away and do not open the cover. If there is fire or smoke, leave the building and call 911.
