Buffet line in commercial kitchen. There are (2) commercial grade 20 amp GFCI's which share a neutral tied to a 2 pole 20A breaker, fed by 12 awg thhn wire in EMT conduit. The kitchen plugs in the food warmers at meal times. They draw less than 20 amps, the breaker never trips. Over time, the neutral on the faceplate of the GFCI's keeps melting. I have replaced the GFCI's more than once. The wires are undamaged but the faceplate where the N plug goes in melts. What is going on?
