The argument is, if the wattage of 2 heating cables in one receptacle are different, will the GFCI trip? One of my employees thinks the load needs to be balanced and the heating cables each need to be on their own single pole GFCI breaker.
Randy,
It makes no difference, all the GFCI is monitoring is a current imbalance, between the Line and Neutral conductors in the circuit.
GFCI's do not differentiate between sizes of load on the same circuit, they are after all, only a safety device, designed to trip on "earth leakage".
Hope the job goes well.
