A dedicated circuit serves one appliance and nothing else: its own breaker, its own wire run, sized for the load. Air conditioners, EV chargers, electric ranges, dryers, water heaters, and workshop equipment all require one — sharing a circuit with a big load is how breakers trip and wires overheat.
We install dedicated circuits across Stuart and Martin County for both trades we serve: the AC systems we install and every other large load in the house. Permitted, inspected, and priced in writing.
What Needs a Dedicated Circuit
Central air conditioners and heat pumps, mini-splits, electric water heaters, electric ranges and dryers, EV chargers, standby generators (via transfer switch), sump and well pumps, and workshop equipment like welders and large compressors. Code requires dedicated circuits for most of these — it is not optional, and it is not a suggestion.
If a large appliance shares a circuit with general outlets or lighting, that is a problem waiting for a hot afternoon to reveal itself.
Sizing It Right
The breaker protects the wire, and the wire has to carry the load with margin — typically sized at 125 percent of the appliance's continuous draw. We read the equipment nameplate, check the manufacturer's specs, and run the wire and breaker to match.
Undersized is dangerous; oversized on the breaker side defeats the protection. Getting both right is the whole job, and it is why a dedicated circuit is electrician work, not a handyman special.
Part of Every AC and EV Install
Because we install air conditioning and EV chargers too, dedicated circuits are baked into those quotes — not a surprise add-on discovered mid-job. Our electricians scope the panel capacity, the wire route, and the disconnect placement when we scope the equipment.
One company, one written price, both trades. That is the advantage of a shop that does AC and electrical equally.
Common questions
Why does my new AC need a new circuit?
Because the old circuit was sized for the old unit — or was never dedicated in the first place. The new system's nameplate dictates the wire and breaker size, and code requires the circuit to match.
Can an EV charger share a circuit with the dryer?
No. EV chargers pull full rated current for hours and require their own dedicated circuit. Sharing would overheat the wiring or trip the breaker constantly.
How long does it take to add a circuit?
Most single-circuit installs finish in half a day to a day, depending on the panel location and the wire route. We confirm timing with the quote.
Do I need a permit for a new circuit?
Yes. New circuits require an electrical permit and inspection, which we handle.
