When a panel needs replacing, not repairing

Most panels we look at are fine. A few are not, and the difference is usually visible in the first two minutes.

A breaker that trips is doing its job. A panel that runs warm, smells faintly of hot plastic, or has rust tracking down the inside of the door is telling you something else. Here is what we actually check on a service call before we say the word "replacement".

Capacity comes first. A 100A service was generous in 1975 and is tight now. Add a heat pump, an EV charger, an induction range, or a hot tub and you are asking a service to carry roughly twice what it was sized for. We run the load calculation before recommending anything, because sometimes the answer is load management rather than a new service — that is a cheaper conversation and we would rather have it.

Then the panel itself. Federal Pacific Stab-Lok and Zinsco panels have a documented history of breakers that fail to trip under fault. If you have one, we will tell you plainly and we will not try to add to it. Rust inside the enclosure means water has been getting in, and water and bus bars do not coexist. Double-tapped breakers, missing knockouts, and aluminum branch wiring are all fixable, but they tell us how the panel has been treated.

Two findings mean we do not leave it as-is: scorching or melted insulation at a breaker, and a bus bar that is pitted or discoloured. Both mean heat where there should not be any, and both get addressed the same day, even if the full replacement is scheduled later.

A service upgrade in a typical Bristol County house is a one-day job for us, plus the utility disconnect and reconnect and the town inspection. We pull the permit, coordinate the utility, and label every circuit before we leave. If the answer is that your panel is fine, that is a free answer and you will get it straight.
