Any guidance or anyone familiar with whether or not gfci is required for 20 amp 3ph twist locks in commercial/Industrial metal fabrication shop? I have read the articles in the other portion of 210 as well as requirements for 15 or 20 amp 120 volt receptacles where welders are used. Seems somewhat Grey to me. The other locations list garages, service bays etc but was interested to know if a fabrication shop would be viewed as a similar install ? Any help is appreciated thank you
