Frequently Asked Questions

How long does an electrical panel replacement or upgrade typically take?

A standard electrical panel replacement or upgrade usually takes one full day. The power will need to be shut off for most of this time, so homeowners should plan accordingly. Complex jobs, or those requiring extensive wiring changes, may take up to two days.

Why is my new electrical panel still tripping breakers after a recent upgrade?

If your new panel is tripping breakers, it usually indicates that the new breakers are correctly sensing an overload or a fault on a specific circuit. The problem is likely with the wiring, an appliance, or an overly high power draw on that circuit, not the panel itself. A circuit diagnostic is needed.

What kind of maintenance does an electrical panel need?

Electrical panels require very little maintenance, but they should be inspected every 3 to 5 years, particularly in older homes. An inspection checks for corrosion, loose connections, signs of heat stress, and proper breaker function, which helps prevent failures and fire hazards.
