Signs You Need a Panel Upgrade
An outdated electrical panel is a safety risk and limits your home capacity. Here is what to watch for:
Frequently Tripped Breakers
If breakers trip regularly, your panel may not have enough capacity for your electrical load.
Flickering Lights
Lights that dim or flicker when appliances run indicate an overloaded or failing panel.
Burning Smell or Heat
Any burning smell from your panel box is a serious warning sign requiring immediate attention.
Older Fuse Box
Fuse boxes in older homes should be upgraded to modern circuit breaker panels for safety and capacity.
Adding High-Load Appliances
EV chargers, hot tubs, HVAC systems — all require panel assessment before installation.
Home Renovation
Adding square footage or a major remodel almost always requires a panel upgrade or expansion.
