Panel replacements, fuse-box changeouts and 200 or 400 amp service upgrades for homes and businesses across Anne Arundel County, including emergency panel replacement when one fails.
Kitchens, heat pumps, EV chargers, hot tubs and home offices all add load. If your panel is full, old or tripping, it is usually the first thing that needs attention before any of those projects.
J Prime Electric replaces worn and undersized panels, upgrades the service coming into the building, and adds subpanels for garages, additions and pool equipment. We handle residential panels and commercial service upgrades for businesses that are adding equipment or expanding.
We pull the permit for every panel and service change we do, schedule the inspection, and coordinate with BGE when the service itself is being upgraded. For homes in Bowie and parts of Prince George's County, we coordinate with whichever utility serves the address. You get one point of contact from the first look at your panel to the final inspection.
A panel upgrade is often the first step of a bigger plan. If you're adding an EV charger, a Generac standby generator or a finished basement, we size the new panel for what's coming, not just what you run today.

A surge protector installed at your panel helps protect the whole home's electronics and appliances from power surges, not just what's plugged into a power strip.
We can add one during a panel upgrade, or install it on its own in your existing panel.
Downtown rowhouses, Murray Hill and West Annapolis houses, and mid-century homes on Annapolis Neck often run on panels that have been extended again and again. Inside city limits, permits come from the City of Annapolis rather than the county, and we file them for you. To confirm
More about electrical work in AnnapolisPlenty of post-war homes in Glen Burnie, Ferndale and along Mountain Road in Pasadena still have fuse boxes or small services. A changeout to a modern breaker panel gives you room to add circuits and makes it easier to see which breaker controls what.
More about electrical work in Glen BurnieMany homes on the Mayo peninsula and along the South River began as summer cottages. When they became year-round homes with central air, electric heat and modern kitchens, the electrical service didn't always grow with them. We check the load and tell you honestly whether an upgrade is needed.
