The Thomas Edison difference
King of Prussia electricians from Thomas Edison Electric cover one of the bigger communities in Montgomery County, home to 25,857 people across ZIPs 19406 and 19487. Bridgeport and Audubon border it, with Norristown and Fairview Village close by too.
Thomas Edison Electric is family-owned and multigenerational, licensed under PA075449 and fully insured in Pennsylvania. The electricians on every job are our own staff, not subcontractors, and they answer calls 24 hours a day, 365 days a year, weekends and holidays included. You get a price in writing before work starts, and a late arrival costs us the dispatch fee, not you. Call 610-270-9700 when the job comes up.
Every call gets the same licensed electrician, whether it's one outlet or a full panel swap.
Aluminum branch wiring, 100-amp service and the occasional Federal Pacific or Zinsco panel are what we look for.
Meter work and service upgrades get scheduled directly with PECO.
Every job comes with a written number up front, no exceptions.
Weekends, holidays or the middle of the night, the same crew answers, and a late arrival waives the dispatch fee.
Over 37,000 jobs completed since 2021, and a 4.8-star rating on Google.
We're dedicated to building lasting relationships with every client through exceptional service and guaranteed results.

Transparent pricing means written quotes with no surprises.
Most of King of Prussia's housing went up around 1978. That build era leaves aluminum branch circuits, panels capped at 100 amps, and outlets with no ground pin. Some panels still carry the Federal Pacific or Zinsco name, both recalled brands. None of that means a full rewire. It means a careful check, starting with what's behind the panel door.
Bridgeport sits two miles off, Norristown not much further, and Audubon and Fairview Village round out the closer side of the map. Wherever the call comes from, it's one of our own electricians who shows up, not a subcontractor, driving a van stocked before the shift started. Dial 610-270-9700 and talk to someone who can get a crew moving the same day.
PECO keeps the lines up outside; what a storm does to the wiring past your meter falls to us. Montgomery County took a hard hit in September 2021, when the remnants of Hurricane Ida flooded basements and knocked out power block by block. A panel that sat under water that week is worth a licensed electrician's look before it goes back to work.
A 100-amp panel was standard when most of King of Prussia went up, and it shows once a house gains central air, an electric range and a car charger at once. We size a panel upgrade to what the home runs today, not 1978, pulling the Federal Pacific or Zinsco unit first if that's what's behind the door.
Loose aluminum connections cause more service calls here than almost anything else. A warm switch plate, or a light that dims when the dryer runs, is usually the tell. We fix the connection with approved hardware instead of replacing wire that doesn't need it, and ground two-prong outlets while we're already in the box.
Newer demands get their own conversation: a dedicated line for a home EV charger, or a standby generator sized for the next outage. We sell and service Generac units too.
Permits for electrical work in King of Prussia go through the township, not a borough hall, since the community was never incorporated on its own. Pennsylvania's Uniform Construction Code still applies, with a third-party firm handling plan review and inspection. Once you approve the written quote, pulling the permit and scheduling that inspection is on us.
Power comes from PECO Energy Company, so anything touching the meter, a bigger service, a relocated meter socket, a full panel swap, waits on a scheduled PECO appointment, which we set up. A line down in the street is PECO's crew to send; a breaker that won't reset inside your house is ours, any hour.
Our Pennsylvania and New Jersey experts are ready to resolve your electrical woes.

I was really impressed with Don and Engeli and the work they performed for me. We had a discussion on the best way to run the new line for the septic pump and I really appreciated the extra effort they made to keep the esthetic of my home's exterior. They were pleasant and professional and all my fans and lights work great! They were patient and waited until I approved everything. A great team!

Had a back up generator installed by Dennis. He did a wonderful job. Dennis is very knowledgeable, thorough, patient and goes above and beyond. Will definitely be using Thomas Edison for all my electrical. Could not be happier.

Technician came out within an hour for an investigation late at night. The same technician came back the next morning and replaced the breaker panel, meter box, and ran new conduit up to the roof for the connections. Did a fantastic job and everything looks great. Thanks Arthur and Malcolm for your hard work!

King of Prussia Electrical FAQs
Yes, every night and every holiday. Our electricians dispatch from their own homes in the area, not a distant yard, and the van is already stocked when the call comes in. Dial 610-270-9700 and expect a same-day fix, any hour you call.
Yes. The same electricians who answer calls in King of Prussia also cover Bridgeport, Norristown, Audubon and Fairview Village, so an address near the border doesn't change who shows up or what it costs.
Almost always the panel. Many homes from that period still run on 100 amps, sometimes under a Federal Pacific or Zinsco label that's since been recalled. We check the panel first, then talk through options with a written price attached.
Depends where the problem sits. A neighborhood-wide outage is PECO's territory, and their crews handle the repair. If your house alone lost power, the issue is usually inside your own system, and that part is ours, day or night.
