Your electrical panel is the one part of your home that should be boring. When it starts getting interesting, take it seriously. These are the six signs we never ignore on a call-out.
Breakers that trip repeatedly
One trip is an event. Weekly trips are a pattern — usually an overloaded circuit or a failing appliance, occasionally something worse.
Warmth where there should be none
A breaker, switch or outlet that feels warm to the touch means resistance where current should flow freely. Resistance means heat, and heat is how electrical fires start.
Flickering when appliances start
Lights dimming when the oven or washing machine kicks in suggest the panel is at the edge of its capacity.
A burning smell, even faint
Stop reading, cut the main breaker, and call an electrician. This one is not a maintenance item.
Fuses instead of breakers
Fuse boxes were fine for the loads of 1970. They are not fine for induction hobs, EV chargers and heat pumps.
No differential protection
Modern standards require residual current devices (RCDs) that cut power in milliseconds when current leaks. If your panel has none, an upgrade is a safety matter, not a comfort one.
The good news
A panel upgrade is a one-day job in most homes, and it comes with a certificate of conformity. It is the single highest-value safety improvement you can make.
