Electrician for auto repair shops
Lifts, compressors, welders, tire machines and diagnostic equipment, wired for a repair garage, with bright bay lighting and chargers for electric vehicles where the shop works on them.
What the work involves
An auto repair shop needs circuits for lifts, tire machines, balancers and welders wired from each manufacturer's sheet, many at 240 volts and some needing three-phase power. The air compressor is sized under NEC Article 430, and repair garages follow NEC Article 511 for wiring near floor level and in pits where fuel vapor can collect.
Vehicle lifts, tire machines, balancers and welders each come with a manufacturer's sheet that names the voltage, phase and circuit. Many run at 240 volts, and some need three-phase power. We wire each from its sheet, with the disconnects where the code requires them.
The shop air compressor is often the largest motor in the building, with heavy starting current. We size its circuit, disconnect and controls from its nameplate and NEC Article 430.
Repair garages where vehicles are worked on fall under NEC Article 511, which sets rules for wiring near floor level and in pits where fuel vapor can collect. We place receptacles and wiring to the article.
Technicians need bright, even light in every bay and under the lifts. We retrofit and install LED high bays and task lighting.
Shops that service electric vehicles need charging in the bays or the lot, which starts with a load study to see what the service can carry.
Shops grow equipment faster than circuits, so breakers trip and receptacles overheat. We size circuits from the equipment sheets, check the service with a load calculation before adding large equipment, and label the panel.
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.

Most do. The lift manufacturer's sheet names the voltage, phase and circuit, and we wire it to that sheet.
