Your breakers trip more than occasionally
A breaker that trips once during a heat wave is doing its job. A breaker that trips every week — or a main breaker that trips whenever the AC and dryer run at the same time — is telling you the system is out of headroom. Frequent tripping is the most common early warning of an undersized or aging panel, and it only gets worse as you add loads.
The panel is 25+ years old, or a flagged brand
Illustrative photoPanels installed from the 1950s through the 1980s are routinely flagged by home inspectors and insurance companies — especially Federal Pacific (FPE Stab-Lok) and Zinsco. Even mainstream brands wear out over decades: bus bars corrode, breaker contacts loosen, and a panel designed in 1975 was never meant to feed central AC, an EV charger, and a home office at the same time.
No spare breaker spaces, or double-tapped breakers
Open the panel door — just the door, not the inner cover — and look. If every slot is taken, or you see two wires squeezed under a single breaker screw (called double-tapping), the panel has no safe room left. No EV charger, no ADU, no kitchen remodel until that changes.
Heat, smell, or flickering that follows the load
A panel cover that feels warm, a faint burning smell nearby, or lights that dim every time a large appliance kicks on all point to loose connections or an overloaded service. These are not cosmetic quirks. Loose connections are one of the leading causes of residential electrical fires, and they deserve a prompt professional look.
You are still on 60A or 100A service
A 100A service was plenty in 1975. Add central air, an induction range, an EV charger, and a garage workshop, and the arithmetic stops working. If your main breaker reads 60A or 100A and you are planning any addition at all, the service upgrade usually has to come first — everything else depends on it.
What to do next
None of these signs means panic. All of them mean planning. A licensed electrician can run a proper load calculation, check the panel's brand and physical condition, and tell you whether you need a full 200A upgrade or a smaller, cheaper fix. The worst outcome is discovering the answer in the middle of a remodel.
