Electrician for car washes
Wet location wiring, motors and pumps, controls, vacuums and lighting for tunnel and self-serve car washes, where water, chemicals and constant running wear out wiring that was not built for them.
What the work involves
A car wash needs wiring built for water: wet location enclosures and fittings, GFCI protection where the code requires it, and motor circuits for conveyors, brushes, blowers and high pressure pumps under NEC Article 430. We also wire tunnel controllers, pay stations, chemical systems, vacuum stations and site lighting, and keep connections out of the spray.
A wash bay is a wet location, and every enclosure, fitting and device in it has to be rated for one. We use wet location methods and equipment and keep connections out of the spray wherever the layout allows.
Conveyors, brushes, blowers and high pressure pumps are motor loads with heavy starting current, wired under NEC Article 430 with disconnects within sight where it requires them.
Tunnel controllers, pay stations and chemical systems are wired to the equipment supplier's drawings, so the equipment arrives to power and controls that are ready for it.
Vacuum stations, pay kiosks and site lighting run outdoors and long hours. We wire them for the weather and repair site lighting faults when they come up.
Water in enclosures, corroded connections and GFCI trips are the usual calls. We use rated equipment, seal what the code calls for, and an infrared scan on a maintenance visit finds hot connections on loaded motors before they fail.
Car wash equipment can outgrow a service, so a new tunnel or added bay starts with a load calculation. Inside the city limits, the electrical permit goes through the City of San Antonio Development Services Department, under the 2023 National Electrical Code the city adopted effective May 1, 2025. We pull the permit and meet the inspector.

Water in an enclosure, a damaged cord or a failing motor are the usual causes. We test the circuit and the equipment to find which one, and give you a written price for the fix.
