200-Amp Service Upgrade in Martinsburg, WV
Maxed out on a 60- or 100-amp panel? Assured Electrical Connections upgrades Eastern Panhandle homes to 200-amp service so your AC, heat pump, EV charger, and everything else run without a flicker.
200-Amp Service Upgrades for Modern Eastern Panhandle Homes
If the lights dim every time your central air kicks on, or you can't run the dryer and the microwave together without tripping a breaker, your electrical service is likely undersized for how you actually live. Many Martinsburg and Berkeley County homes were built around 1969 with 60- or 100-amp service that was never meant to carry today's heat pumps, EV chargers, hot tubs, and finished basements. Upgrading to 200-amp service brings your home up to the modern residential standard and gives you the headroom to add what you want.
A 200-amp service upgrade is a complete overhaul of your home's electrical entrance: a new meter socket, heavier service conductors, a new 200-amp main breaker panel, and a properly bonded and grounded system that meets current NEC requirements. Jim Norton, a master electrician with 18-plus years in the trade, performs a load calculation before any work begins so the upgrade is sized to your real and future demand, not a guess.
We handle the whole project from start to finish across the Eastern Panhandle, including the permit through Berkeley County or Jefferson County and the disconnect/reconnect coordination with Potomac Edison. The physical install is typically a single day, with the full permitting and utility process spanning a few weeks. Beyond the convenience, a 200-amp service is a documented, inspected upgrade that boosts your home's value and marketability.
What a 200-Amp Upgrade Actually Does for Your Home
Real, measurable improvements you'll notice the day Potomac Edison reconnects your power.
Capacity for Modern Loads
Run central AC, a heat pump, an EV charger, and a hot tub without overloading your panel. A 200-amp service nearly doubles or triples the capacity of an old 60- or 100-amp setup.
No More Dimming or Tripping
Lights that flicker when the AC compressor starts and breakers that trip when appliances run together are signs of an overtaxed service. Right-sizing the supply puts an end to it.
Room to Add and Remodel
Finishing a basement, building an addition, or adding a workshop circuit becomes simple when your panel has open spaces and real headroom instead of a tapped-out bus bar.
Higher Home Value
An inspected, code-compliant 200-amp service is something buyers and home inspectors look for. It removes a common sticking point and makes your Eastern Panhandle home easier to sell.
A Load Calculation Before We Touch a Wire
We don't assume 200 amps is automatically right for your home, we prove it. Following NEC Article 220, Jim runs a load calculation that accounts for your square footage, HVAC, large appliances, and the EV charger or hot tub you're planning to add. That calculation also justifies the service size on the permit and protects you from an undersized or oversized install.
Code-Correct Grounding and Bonding
A service upgrade is only as safe as its grounding system. We drive two ground rods spaced at least six feet apart and bond the system per NEC Article 250, tying together the grounding electrode conductor, neutral, and equipment grounds at the new service. This is the part that protects your family and electronics during the summer thunderstorms and derechos the Eastern Panhandle is known for.
Everything That Goes Into a 200-Amp Upgrade
From the warning signs to the code requirements, here's how a proper service upgrade comes together.
Signs Your Service Is Undersized
Flickering lights when the AC starts, frequent breaker trips, and a hot or buzzing panel all point to a service that can't keep up with demand.
60A and 100A to 200A
Older Eastern Panhandle homes often still run 60- or 100-amp service. Stepping up to 200 amps is the standard fix for capacity-starved panels.
Sizing With a Load Calculation
Per NEC Article 220, we calculate your home's real demand including HVAC and EV loads so the new service is sized correctly, not guessed.
Grounding and Bonding
Two ground rods set six feet apart and bonding per NEC Article 250 give your upgraded service the safe path to ground it needs.
Powering an EV Charger
A Level 2 EV charger draws serious continuous current. A 200-amp service gives you the capacity to add one without starving the rest of the house.
Permits and Inspection
Every upgrade is permitted through Berkeley or Jefferson County and inspected, so the work is documented and code-compliant for resale.

200-Amp Service Upgrade FAQ
Common signs are lights that dim when your AC or heat pump starts, breakers that trip when you run multiple appliances, and a panel that's full with no room for new circuits. If you're adding central AC, an EV charger, a hot tub, or finishing a basement on a 60- or 100-amp service, you almost certainly need the upgrade. Call Jim at (304) 582-1958 and we'll do a load calculation to confirm.
The physical installation is usually completed in a single day, when your power is off only while we swap the meter socket, conductors, and panel. The full process, including pulling the permit through Berkeley or Jefferson County, scheduling the Potomac Edison disconnect and reconnect, and passing inspection, typically spans a few weeks. We coordinate every step so you're not chasing the utility or the inspector.
Yes. Assured pulls the electrical permit through the Berkeley County or Jefferson County building department and schedules the disconnect and reconnect with Potomac Edison. We also meet the inspector so the work is signed off properly. You don't have to make a single call to the county or the power company.
A 200-amp service requires conductors rated for the load, typically #2/0 copper or #4/0 aluminum service entrance cable. The exact size and material depend on your run length and the results of the NEC 220 load calculation. We size everything to code so it passes inspection the first time and carries your full load safely.
No. Your power is only interrupted during the actual install day while Potomac Edison disconnects the service and we cut over the new meter, conductors, and panel. That outage usually lasts several hours, not days, and we schedule it so you know exactly when to expect it. Once the new service is energized and inspected, you're back to normal with far more capacity than before.
