Damp Location Definition
 
Can some one please help with the definition of a "DAMP LOCATIOn" as it applies to a bathroom. We have an enclosed shower and would like to put track lighting on a beam that is outside of the glass enclosure (but still in the bathroom), but the track is not rated for damp conditions.
Thank you. Steve

Here is the NEC definition


Location, Damp.
Locations protected from weather and
not subject to saturation with water or other liquids but
subject to moderate degrees of moisture. Examples of such
locations include partially protected locations under canopies,
marquees, roofed open porches, and like locations,
and interior locations subject to moderate degrees of moisture,
such as some basements, some barns, and some coldstorage
warehouses.

You will need to meet the clearance requirements for fixtures above and near the tub zone. Here is a good diagram from Mike Holt.

Jim,
In the Mike Holt pic, I see (I think) a wall switch in the 3' zone of exclusion. So, this zone only pertains to lights and not switches (or outlets)?
Thanks,
Bob

Correct.
Switches and receptacles shall not be located within the shower/tub area, but CAN be in the "3 foot zone" outside the tub area.

No. Only receptacles.
Certain lighting IS allowed in the exclusion zone if GFI protected. Most recessed lights do not require GFI protection.

been awhile for me but I thought any electrical you could reach while standing in a tub of water was protected, or is that just whirlpools? sorry for the ignorance

No, not generally. There is no "touch potential" distance code.

Also depends on what you mean by "whilrpool".
Spas and pools have different rules.
