Many Northern Virginia homes from historic cottages in Arlington to sprawling new builds in Loudoun—are running on outdated or overloaded electrical panels. In this expert guide, Master Electrician Peter from PRO Electric plus HVAC explains how legacy systems like Federal Pacific and Zinsco pose serious fire risks, why 100-amp panels can’t handle today’s demands, and what upgrades—like 200-amp service, AFCI/GFCI protection, and outdoor disconnects—are essential for modern safety, efficiency, and peace of mind. Whether you’re dealing with frequent breaker trips, planning to install an EV charger, or simply want to ensure your home meets Virginia’s latest electrical code, this comprehensive guide breaks it all down—county by county.
