What Is an Electrical Wiring Upgrade and Why Is It Needed?

An electrical wiring upgrade replaces outdated or unsafe wiring and brings your home up to current code. Harrison Electric removes knob-and-tube or aluminum wiring, installs modern cable, updates the service panel and grounding (often to 200 amps), and adds GFCI/AFCI protection and surge protection. It is needed to reduce fire risk, avoid insurance issues, and support modern loads like EV chargers and hot tubs. We handle end-to-end work in Minneapolis and Maple Grove homes with licensed technicians.
