Your Local Electric Company in O’Fallon

If your O’Fallon home was built prior to the year 2000, it likely needs substantial electrical updates. While GFCI outlets have been required in new construction since the late 1970s, AFCI outlets only became the standard in 1999. That means if your home is more than 25 years old, it’s likely out of code. If it’s more than 50 years old, it’s likely to need a lot more in electrical services than just outlet updates. Wiring typically only lasts about that long.

Putting in new lighting, adding the most recent safety protections and making sure you have enough power for all of your appliances are just a few of the things you can expect from the right electric company. A qualified electrician can handle any size job, from putting in outdoor lighting to upgrading your panel.
