Metallic conduit in Indoor Pool Room

Status
Not open for further replies.
We are installing conduit through a room in which there will be an indoor pool at a Gym. The last gym that we did had a note on the drawings stating "...all conduit shall utilize corrosion resistant conduit RNC, or corrosion resistant galvanized steel or stainless steel RMC."
Assuming that that is a job specific note, Is there a code requirement for the type of conduit allowed to be used for conduits passing through a pool room?
Are there any requirements for boxes located within the pool room to be rated Nema 4X

What code cycle are you under? The 2017 has added this section about pool rooms as corrosive environments.

680.14 Corrosive Environment.
(A) General. Areas where pool sanitation chemicals are
stored, as well as areas with circulation pumps, automatic chlor‐
inators, filters, open areas under decks adjacent to or abutting
the pool structure, and similar locations shall be considered to
be a corrosive environment. The air in such areas shall be
considered to be laden with acid, chlorine, and bromine
vapors, or any combination of acid, chlorine, or bromine
vapors, and any liquids or condensation in those areas shall be
considered to be laden with acids, chlorine, and bromine
vapors, or any combination of acid, chlorine, or bromine
vapors.
(B) Wiring Methods. Wiring methods in the areas described
in 680.14(A) shall be listed and identified for use in such areas.
Rigid metal conduit, intermediate metal conduit, rigid poly‐
vinyl chloride conduit, and reinforced thermosetting resin
conduit shall be considered to be resistant to the corrosive
environment specified in 680.14(A).
 
Thank you! That is what I was looking for, and that is why I couldn't find it.
The job isn't under that code cycle (actually 2011), but considering the reasoning, I'm sure we'll do it to 2017 standards.
A lot of people said EMT wasn't acceptable, but they couldn't give a code reference.
Thanks again!

Several years ago I got called to connect new pool pumps in an equipment room at the local YMCA that had been flooded (about 5’ of standing water in the room). The EMT they used was essentially gone; just the rusted lower half of the conduit remained. Nothing but bare conductors hanging out everywhere.
