Voltage limitations

[brother]

I was looking at the voltage limitations in 2005 NEC 210.6(A) , 120 v nominal shall not be exceeded. (NO 277/480 or 208)

I thought there was also limitation (120v max) on the light fixtures in bathrooms, and lights over showers/tubs but cant seem to find it. where is it if its in the code??

I hope i don't shake up wrong tower here but anyway there is the limitaion on resdentail system nothing allowed over 250 volts Line to Line or 125 v Line to netural

but in commercal it kinda mute on that one but i did work on few commercal bathrooms some of them used 277v lighting system in there.

I think maybe your commercial bath doesnt fall under the limitation rule. Apparently this limitation is not in the code that i thought it would be. It just says 'and similar occupancies' of a 'dwelling unit. If you look up the definition of a dwelling unit it tells what it is.

It seems for safety reasons the voltage would be limited in a shower/tub zone with a light over it.

Brother.,,

Yes i did read about the dwelling area and not only used in the resdentail area but also used in motel and dorm area [ if they have prodviceation for it ]

and yes that part we are pretty much agree with this one related to the voltage limitation on dwelling area.

Merci,Marc

The fixtures are required to be grounded and have overcurrent protection.

As far as someone changing a lamp while standing in a tub of water IMO at some point you have to let people take care of themselves.
