Protect Your Electrical System Through Our Electric Panel Replacement: Plymouth, MN

In a panel replacement, the amperage remains the same, so it will not increase your home's electrical system capacity to handle more or larger new appliances. Instead, replacement focuses on updating the electrical safety and efficiency of the existing system. This ensures that your electrical panel can properly support the current load without posing a hazard, while also adhering to modern electrical codes and standards.
If you're thinking of investing in an EV charger installation, purchasing high-powered electronics, or any other system that will draw heavily on your electrical system, you will need an electric panel upgrade. Plymouth, MN electricians on our team increase the amperage available to the home, typically upgrading from 100 amps to 200 amps. Through an upgrade, you will be able to add advanced circuit breakers such as GFCI and AFCI, which enhance safety and protect against ground faults and arcs.
If you live in an older Plymouth home, you likely have a fuse box in place. These systems are extremely outdated and violate safety codes. If you have one in place, you need a fuse box replacement.
