I disagree.

How did you determine it is a damp location?
 
Care in how you enter that freezer with emt is also important.We place a 4 square on the outside and run short nipple into the bell box.Foam the nipple after wires are pulled.
 
Condensation can and will still form on the inside of a weather proof raceway and box system even when sealed from the outside. Just look at any raceway system installed outdoors.
 
Look at the evaporater fans in the cooler, the wiring is not in sealed compartments, at least the ones I have done haven't been.

uhhh... no. Refrigeration equipment necessarily dehydrates the refrigerated area. It's physics, baby. Some packing houses and cold storage houses purposely add moisture back into the refrigerated atmosphere to protect their stored products and combat the dehydration caused by refrigeration.

Sometimes "wet location" wiring methods are prudent, if the inside of the refrigerated space is subject to periodic washdown.

In fact, the wiring inside of them just free airs from fan to fan. *Gasp* they must be really unsafe. ;)
 
Most people will install bell boxes, but I had one that didn't and when I pressed the issue he called the manufature of the cooler and they told us that is was not required to be a bell box. Of course my first question is then why do you spend all the money to install weather type fixtures in there if it's not required. I never recieved an answer.

I was told once by a Health Department Inspector (how true it is I don't know, it's just what he told me) that it is required for providing protection for the lamp and broken glass contaminating the food in the cooler.

Greg, a standard 4" sq can be used in a damp location. 314.15(A) (2002)

FMC can be used in damp locations.

But along with the others do not believe every walk-in cooler is a damp location.
 
When a person orders a brand new walk in box, they have the option of having boxes cast in the foam of box for various things, with stubs out of the top of the box. The box manufacturers use handy boxes cast in the foam, and FMC stubs hanging out of the top of the panels.

Roger, I would believe that, they always made them wrap the tubes if they used strip type flouresents in the kitchen area.

John, it made sense to me too. :)

I would bet that if an Inspector called the walk-in a damp location, it

would be hard to convince him/her or any higher official that it is 'dry'.

I say it's 'dry' until the door is open to long and the walls sweat like mad.
