Why 200 amp service upgrade comes up in Arlington
Arlington homeowners expanding Cape Cods and Colonials with additions, finished basements and second stories, or electrifying with heat pumps and EV chargers, often outgrow 100 amp services. A 200 amp upgrade usually includes a new meter base and service entrance coordinated with Dominion Energy, and some homes switch from an overhead to an underground service during a renovation. The county reviews load calculations with the permit.
Arlington has offered energy programs that change over time. Permits come from Arlington County's permit office. Ask for the load calculation in writing so later projects can be planned.
- Arlington's Cape Cods and bungalows in Lyon Park, Cherrydale and Westover were built when a 60 or 100 amp service was plenty, and today's renovations often add a heat pump, an induction range, an EV charger and a finished basement all at once.
- That usually means a 200 amp upgrade with a new meter base.
- For detached homes, a load calculation decides whether a 40 or 48 amp charger fits on an older 100 amp service, or whether a lower setting avoids an upgrade.
- Older 100 amp panels may need an upgrade to make room.
