Frequently asked

Panel Installation Questions Answered

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

How do I know if I need a new electrical panel?

Signs include frequent tripped breakers, flickering lights, a panel over 20-25 years old, or a home that's outgrown its current amperage. If you're adding an EV charger, hot tub, or major appliance, an upgrade is often needed as well.

How long does panel installation take?

Most residential panel installations are completed within a day, though timing depends on the panel size, wiring condition, and whether the utility company needs to disconnect service beforehand.

Will my power be shut off during installation?

Yes, power to your home is turned off during the swap for safety reasons. We schedule the work to minimize downtime and let you know ahead of time roughly how long to expect.

Do I need a permit for a new panel?

Panel installations typically require a permit and inspection through the local municipality. We handle the permitting process and schedule inspections as part of the installation.

What size panel do I need?

Panel size depends on your home's square footage, appliance load, and future plans like EV charging. We perform a load calculation during the site evaluation to recommend the right amperage.

Can you install a panel for a commercial property?

Yes, we install and upgrade panels for both residential and commercial properties throughout Philadelphia and the surrounding region, sized to match business equipment and occupancy needs.

What areas do you serve for panel installation?

We install electrical panels throughout Philadelphia and nearby communities including Upper Darby, Norristown, King of Prussia, Bensalem, and Camden and Cherry Hill in New Jersey.
