EV Charging Outlet NEMA 14-50 — Garage, Panel-Adjacent

Pay when you book · morning (8–12) or afternoon (12–4)
What's included
Install one NEMA 14-50 receptacle in the garage within 10 ft of the existing panel, surface-run in conduit, on a new 50A GFCI-protected 2-pole breaker (breaker, conduit, wire, industrial-grade receptacle included), with torque-spec terminations and load test. HARD ASSUMPTIONS — verified before work starts: panel is in or adjacent to the garage, has two open adjacent breaker spaces, and a load calculation confirms spare capacity for a 40A continuous load. If the panel lacks space or capacity, or the run exceeds 10 ft, this task does not apply and the job is visit-quoted as panel/new-circuit work (excluded from this price book). Hardwired wall chargers and load-management devices also excluded.

FAQ
Common questions
How much does EV Charging Outlet NEMA 14-50 — Garage, Panel-Adjacent cost in Centennial?
$595.
How do I book?
Press Book next to the job, pick a date and a morning (8–12) or afternoon (12–4) window, and pay in full. We confirm within 24 hours or refund you in full.
Do I need a panel upgrade for a Level 2 charger?
Often no. We run a load calculation on your existing panel before quoting. If your service has headroom, a dedicated 240V circuit fits without an upgrade. If the load is tight, load management can delay or avoid a 200A upgrade; we only recommend an upgrade when the math actually requires it.
Should I choose the Tesla Wall Connector or a universal charger?
The Tesla Wall Connector is the cleanest fit for Tesla vehicles and is installed by our Tesla Certified Installer. Universal J1772 or NACS units suit households with mixed EV brands or drivers who want one charger for future vehicles. We match the hardware to what you drive now and expect to drive next.
Can you install a charger outside?
Yes. We mount chargers on garage interiors or weather-rated exterior locations, with conduit, enclosures, and hardware rated for Colorado sun, snow, and freeze-thaw. The install is permitted and inspected like any permanent electrical addition.
Do EV charger installs require a permit?
Yes — a Level 2 charger adds a dedicated 240V circuit, which requires a municipal electrical permit and inspection. We pull the permit and schedule the inspection as part of the project.
What if my household has more than one EV?
We plan for total charging load from the start. Load management shares the available capacity between vehicles, charges when demand is low, and keeps most homes off a costly panel upgrade. We size the circuit and settings for your current and expected fleet.
