Frequently asked

Panel Upgrade Questions

Get clear answers about electrical panel upgrades, preparation, timing, maintenance, and what to expect before requesting an estimate.

How do I know if I need a panel upgrade?

Signs include frequently tripped breakers, flickering lights, a panel with a fuse box instead of breakers, or plans to add an EV charger, hot tub, or major appliance. If your panel is rated below 100 amps, it likely needs replacing.

How long does a panel upgrade take?

Most residential panel upgrades take one full day, though larger commercial jobs or those requiring utility coordination can take longer. We'll give you a clear timeline after the initial evaluation.

Will my power be shut off during the upgrade?

Yes, power to your property is shut off temporarily while the old panel is removed and the new one is installed. We schedule this portion of the work to keep the disruption as brief as possible.

Do I need a permit for a panel upgrade?

Most panel upgrades in Philadelphia and surrounding areas require a permit and inspection. We handle the permitting process and coordinate with local inspectors as part of the job.

What panel size do I need for my home?

It depends on your home's square footage and electrical load, including appliances, HVAC, and any planned additions like EV charging. We calculate this during our on-site evaluation and recommend the appropriate amperage.

Can you upgrade a panel for an EV charger?

Yes. Many homes need a panel upgrade before adding an EV charger, since older systems often lack the spare capacity. We can size the new panel to support both existing circuits and the charger.

Do you work on both residential and commercial panels?

Yes, we handle panel upgrades for houses, multi-unit properties, and commercial buildings throughout the Philadelphia area, including King of Prussia, Norristown, and Camden.
