A dedicated circuit is a circuit that serves only one appliance or outlet, ensuring it receives consistent, uninterrupted power without sharing capacity with other devices. Many appliances in modern Northern Virginia homes require dedicated circuits by code, including refrigerators, dishwashers, microwaves, garbage disposals, washing machines, dryers, HVAC systems, and electric water heaters. Without dedicated circuits, high-draw appliances share power and cause tripped breakers, dimming lights, and potential overheating of wiring. AJ Long Electric installs dedicated circuits for all residential and light commercial applications throughout Fairfax County, Loudoun County, Prince William County, and Arlington. Our electricians run properly sized wiring from your panel to the appliance location, install the correct receptacle type (120V or 240V), and ensure the circuit is protected with the appropriate breaker. We also install dedicated circuits for home offices, workshop equipment, server racks, wine coolers, hot tubs, and electric vehicle chargers. Every installation includes a load calculation to verify your panel can support the new circuit, proper wire sizing per NEC ampacity tables, and a permit when required by your jurisdiction.
