Breakers tripping when two things run at once? A dedicated circuit gives one appliance or device its own breaker and wiring — the safe, code-compliant way to power window ACs, EV chargers, hot tubs, freezers, and workshop tools.
Most older Baltimore homes were wired for a fraction of today's electrical load. Whole rooms often run off a single shared circuit, so plugging in a space heater, microwave, or window AC trips the breaker or dims the lights. A dedicated circuit fixes that by giving the high-draw device its own line straight from the panel — no more competing for power.
It's not just convenience. The National Electrical Code requires dedicated circuits for certain equipment — kitchen appliances, HVAC, EV chargers, and more. And there's a safety side: an overloaded shared circuit runs hot, and heat inside your walls is exactly how electrical fires start.
Common reasons homeowners add a dedicated circuit: a window or through-wall AC unit, a garage freezer or second refrigerator, a microwave, an EV charger, a hot tub or spa, a sump pump, workshop tools, a home office, or a space heater that keeps tripping the bedroom circuit.
A standard dedicated circuit runs $350–$800. A 120V circuit for something like a microwave, window AC, or freezer is on the lower end; a 240V circuit for a dryer, range, hot tub, or EV charger is higher because it needs heavier wire and a double-pole breaker. The biggest cost driver is the distance from your panel to the device — a run in the basement right below the panel is quick, while a run to a second-floor room or detached garage takes more wire and labor. We quote flat-rate before we start.
120V circuits power most standard plug-in devices — outlets, microwaves, window AC units, and freezers. 240V circuits power high-draw equipment like electric dryers, ranges, hot tubs, welders, and EV chargers, and they use two hot wires plus a double-pole breaker. We size the breaker and wire to your specific equipment so it runs safely and to code.
Common signs: a breaker trips whenever a specific appliance runs, lights dim when a large device kicks on, you're running equipment off an extension cord or power strip long term, or you're adding new equipment like an EV charger, hot tub, window AC, or workshop tools. Any device that draws heavy or continuous power should be on its own circuit.
Yes — adding a new circuit requires a permit and inspection in Baltimore City and Baltimore County. We pull the permit and coordinate the inspection as part of the job, so the work is on record and done to code.
