DEDICATED CIRCUIT
Single-equipment circuits sized for the load: window AC, hot tub, EV charger, large appliance, server rack, or workshop tool.
Keil Electric installs dedicated circuits across San Diego County and the Austin metro for high-draw equipment that should not share a circuit. Window AC, hot tubs, ranges, dryers, EV chargers, server racks, workshop tools. Sized at NEC tables, breaker matched to conductor, terminated at a dedicated outlet.
Same scope on either side. Pick the shop that covers your area and we will route you to the right crew.
Equipment nameplate gives the running and starting amperage. NEC requires the breaker and conductor to be sized for 125% of continuous load. We confirm the equipment specs, look up the wire size and breaker in NEC tables, and install accordingly.
Window AC: 15A or 20A, 120V. Range: 50A, 240V. Dryer: 30A, 240V. EV charger Level 2: 40A or 50A, 240V. Hot tub: 50A or 60A, 240V GFCI. Workshop tools: varies, often 20A or 30A. Server rack: 20A on a UPS-fed circuit.
The receptacle has to match the circuit and the equipment plug. NEMA 5-20 for 20A 120V, NEMA 14-30 for 30A 240V dryers, NEMA 14-50 for 50A 240V ranges and EV chargers, NEMA 6-50 for some welding equipment. We pick the right NEMA configuration for the equipment.
Some dedicated circuits require GFCI protection: hot tubs and pool equipment, garage receptacles, outdoor receptacles, and within six feet of water. We provide GFCI via the receptacle or the breaker depending on the install and confirm the test function.
You confirm the equipment running and starting amperage. We size the circuit accordingly.
Breaker size, conductor gauge, receptacle type, route, and cost. Fixed-price quote.
Cable run, breaker installed, receptacle installed at the equipment location.
Verify the circuit holds under load, GFCI functions where required, and document the install.
Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.
Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.
Sharing a circuit with high-draw equipment causes nuisance trips, overheating, and equipment damage. A dedicated circuit isolates the load and protects the rest of the panel.
Real work from our San Diego and Austin shops. Same standards, same warranty, every job.
For dedicated circuit installation, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Most dedicated circuit installation calls start when the homeowner is planning ahead: a renovation, an addition, an EV charger, a generator, a panel upgrade, or any project where the existing electrical needs to be sized correctly for the new load. The earlier we walk the property, the cleaner the project sequencing. Bringing us in before the drywall closes saves rework. Bringing us in before the contract is signed with the GC saves scope confusion. We are happy to walk a property at the planning stage even if the install is still months out.
A walk of the property with attention to the panel (age, capacity, available breaker space), conduit accessibility, attic / crawlspace conditions, and the load picture (current loads + planned future loads). For installs that touch the service drop, we factor utility coordination from the start. The estimate we leave with is fixed for the scope as walked. Change orders only happen for genuinely new findings during the work, you hear about them before we proceed.
Dedicated circuit installation is one of the most common requests during equipment upgrades and additions. The work is straightforward when sized correctly. We do these for window AC adds, ranges, dryers, EV chargers, hot tubs, server racks, and shop tools weekly between both shops.
Window AC units pull 10-15 amps continuously. Sharing a 15A or 20A circuit means the AC plus a few other devices easily exceeds the breaker rating, leading to nuisance trips. A dedicated 20A circuit eliminates the issue.
In most jurisdictions a homeowner can legally do this work. The risk is sizing wrong (undersized conductor, oversized breaker) which creates a fire hazard, or terminating wrong which creates a safety or code-compliance issue. A licensed install includes the right gear and code expertise.
Cost depends on cable length (panel to equipment), conductor size, finish-wall fishing complexity, and breaker availability in the panel. We quote in writing.
New circuits originating at the panel typically require a permit. We pull it where required.
Options are tandem breakers (when the panel allows), a sub-panel installation, or a panel upgrade. We tell you in writing which path applies.
A licensed electrician sizes the circuit to the equipment, walks the route, and writes the install in fixed-price terms.
