We are having a problem in our shop with GFCI's tripping that supply power to our parts tumbler. They are the type that are full of ceramic beads and have a submersible pump in a bucket of water that circulates water through the machine. We have replaced motors and the GFCI outlet many times and still keep having issues. Any suggestions? Is the pump and tumbler both required to have GFCI protection per the NEC?
