I do a lot of troubleshooting on various electrical equipment as an electrical technician at a resort. A few years ago I had a situation where electric steamer showers in a hotel were shocking some guests. After I located a faulty steamer element that was going to ground (milliamps), I decided to put GFCI breakers on all the steamers in the whole building. My question is this; why does the code not require GFCI breakers on steam heating units like this and why are water heaters not NEC required to have GFCI protection also? Hot tubs are, what's the difference? I realize you step into a hot tub and touching ground, but the same hazard exists in the shower with hot water coming from the water heater element.
