Looking for some insight. I've been building quick lube shops all around the southeast for the past few years. These are classified as minor repair garages under NEC code. Each location gets 3 automotive lifts and 2 oil evacuators. The electric requirements are 208/240v 20 amps for both pieces of equipment and only has 2 hots and a ground. Each piece of equipment terminates to a L6-20 (twist lock plug) for a means of disconnect. Today I felled the final electric inspection in Rock Hill, SC because the equipment breakers weren't GFCI. I know 511.12 states all 125v receptacles need to be GFCI protected. However the inspector couldn't quote which code this violated. We've come across this many times before and have to install ground fault breakers and once we get a C.O. go back and switch them out. The electric motors don't play nice with the ground fault. The city is using 2020 NEC code. So my question is what's the code on this? Thanks, Charles Godfrey
 
I think that (8) has it covered.

Welcome to the Forum.

210.8(B) Other Than Dwelling Units.
All 125-volt through 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to ground, 50 amperes or less, and all receptacles supplied by three-phase branch circuits rated 150 volts or less to ground, 100 amperes or less, installed in the locations specified in 210.8(B)(1) through (B)(12) shall have ground-fault circuit-interrupter protection for personnel.
(1) Bathrooms
(2) Kitchens or areas with a sink and permanent provisions for either food preparation or cooking
(3) Rooftops
Exception: Receptacles on rooftops shall not be required to be readily accessible other than from the rooftop.
(4)Outdoors
Exception No. 1 to (3) and (4): Receptacles that are not readily accessible and are supplied by a branch circuit dedicated to electric snow-melting, deicing, or pipeline and vessel heating equipment shall be permitted to be installed in accordance with 426.28 or 427.22, as applicable.
Exception No. 2 to (4): In industrial establishments only, where the conditions of maintenance and supervision ensure that only qualified personnel are involved, an assured equipment grounding conductor program as specified in 590.6(B)(2) shall be permitted for only those receptacle outlets used to supply equipment that would create a greater hazard if power is interrupted or having a design that is not compatible
with GFCI protection.
(5)Sinks — where receptacles are installed within 1.8 m (6 ft) from the top inside edge of the bowl of the sink
Exception No. 1 to (5): In industrial laboratories, receptacles used to supply equipment where removal of power would introduce a greater hazard shall be permitted to be installed without GFCI protection.
Exception No. 2 to (5): Receptacles located in patient bed locations of Category 2 (general care) or Category 1 (critical care) spaces of health care facilities shall be permitted to comply with 517.21.

I'm sorry. Just for clarification, does this mean that these outlets need to be GFCI protected? Even though the equipment is not designed to be GFCI capable (no neutral). Also seems like it would produce a hazardous situation if a automotive lift lost power while a car is up in the air and in a unlatched position. I get to reading some of these codes and it sometimes tough to decipher wordage. Thanks again, Charles

Yes, GFCI required.
NEC does not care about equipment design or it's suitability for use with GFCI protection.
