Would a Steam Unit, 240v., for a shower be required to have the continued use, 1.25% added and or GFI protected?

I have not seen this job yet, I just received a call from the Plumber who asked if I could wire up the new replacement.
 
I would say "No" and "No," in that order. You don't usually run showers for 3 hours, and nothing other than 125V circuits ever needs a GFCI.

A 220v hot tub or hydromassage tub does need GFCI protection so I disagree with that comment.

The steamer may require it by the manufacturers instructions. I believe the last one I did (long time ago) did not require GFCI protection.

It would ultimatley depend on the manufacturers requirements.

..............but............

In my Opinion....no, and no.

They are not on continuously, otherwise you could steam lobsters in the shower stall.

The basically operate the same as a storage type water heater (only they get hotter, make steam, and have more sophisticated controls) which are not required to be GFI protected.

Get the Make and Model and do a search for the specs.
Pay attention to 422.11(F).

Just my opinion
Hope this helps

Storage Water Heater is considered continuous under Article 422.13. This was the basis of my question.

I really don't think that they are in the same classification because the steam unit makes the steam as it is needed.
It will turn on and off automatically to acheive the set point temperature.

Wait.....that's what a water heater does:confused:

I do know that I once installed a 9KW 240V/1 steam generator (same application as yours) and the manufacturer specified a 40A circuit.

I would check the specifications before I went any further.
I can't find any direct reference in the Code.

Thanks Steve. I hope you know I was not being confrontational. I just wanted to be prepared if indeed I get the call.

Again, thanks
