Wiring Commercial Garages and Repair and Storage Facilities: Some garages and facilities may have more electrical requirements than meet the eye

摘要

A commercial garage may not seem like much of an electrical challenge at first glance, but upon closer inspection you may discover more than just the usual lights, fans, air compressors, and lifts. If the garage has work pits, fuel storage systems, or fuel dispensing equipment, your installation needs to comply with the requirements of Art. 511. Otherwise, it could jeopardize the safety of those who work in or visit the facility. Art. 511 applies to areas used for service and repair operations of self-propelled vehicles-including passenger automobiles, buses, trucks, and tractors-that use volatile flammable liquids or gases for fuel or power. You can apply Art. 511 requirements to residential or repair garages for watercraft, 4-wheelers, or motorcycles, but it's not a Code requirement. Installations that likely fall within the scope of Art. 511 include automobile service/repair centers; service and repair garages for commercial vehicles, such as trucks and tractors; and service and repair garages for fleet vehicles, such as cars, buses, and trucks.
