I wired a metalworking shop and today was their first day going to work. And all the 120v GFCI's nuisance trip. Now I believe that part of the issue is that I used "RPP" brand GFCI's instead of my usual P&S Legrand favorites. I used this off brand because that's all the supply house had at the time, I specifically asked for P&S and they said they were unavailable. Anyways I've already checked the cord and plug equipment to see if there was leaking ground current and none of the equipment had even 1 mA of leakage. I believe their older equipment is tripping the GFCI's because of inductive kickback. I'm in the process of changing all the GFCI's to P&S Legrands but just in case this doesn't fix the issue for everything what are some other solutions? I don't think they would be excited about me removing the power cords and hardwiring the equipment. I seen a "snubber" might help but I can't find a manufactured solution there. Would a surge supressor or line conditioner work? Just trying to not throw the code book out the window and trashcan the GFCI's too fast. I can easily imagine a situation in there where a piece of metal could smash a power cord and the GFCI needing to be there.
