Outlets in a walkin.

I have a customer who wants to install some general use utility outlets inside their walkin which is used for vegatable reasearch. As long as they are GFCI and wp in use covers, any problems?
 
I assume this is a walkin cooler, in a non-dwelling occupancy.

That said, take a look at 210.8(B) for the short list of required GFIs. Until more detail is provided, I'm not sure that you are required to install GFIs.
 
I made the call one time on a walkin because they installed regular 4/s boxes. I figured that the manufactuer installed weather tight boxes and fittings, but I could not get anyone to back up the call, including the manufactuer. They claim it's not really a damp location.:confused:

Good call, I didn't even think of a walkin cooler.

We did a job with various types of receptacles in a walk-in. The space was used to prepare sliced meats, sandwiches, marinades, vacuum sealed foods, etc. that the health code required to stay cold throughout the process. We used all Bell boxes with flip lids. The 120 volt receptacles were all GFCI for safety because you were in a totally metallic space and could easily ground youself out. The other, 208 volt stuff was regular receptacles with flip lids also. We more or less wired it like you would if you were doing an outdoor job. I think it was well worth the effort.:smile:

I dont see where GFCI is required for that location based on 210.8 - Other than dwellings ( I will assume )...It is not a kitchen in that location so not sure it pertains.

I guess you would need to ensure any conduits that run in ( if thats what you are doing ) are sealed because of temp changes but unless they spray down veggies in their...which they might I guess GFCI is a good thought...because it brings in 406.8 and so on.
 
I wire walk-in's just like outdoors, due to the way they're washed down. In normal use, the air inside a walk-in is fairly dehydrated.

I have always done it that way as well, however, Mr. 24,000 Post Man has told me has hooked up coolers that came from the factory with regular FMC and 4" square boxes.

I think we've had this discussion before and the consensus was that there is no basic requirement to wire them with WP methods. I think it's good practice to, but not NEC required.
 
Many times I think the use of bell boxes makes matters worse, if your not dealing with wash down issues. The coolers I work on rarely (OK never :roll:) get hosed down.

If you going to use WP methods maybe small drain holes would be a good idea.

That said most times the specs require WP methods. I did do a 7-11 and the walk in cooler there was a prefab unit wired with FMC and 4" sqs.

I agree, I remember a service call I went on a while back for a walk-in freezer. The switch was in a bell box and had a conduit that went through the wall to the outside and wan't properly sealed. When I went to open the switch box the entire box was a solid block of ice. Needless to say I found the problem.:D
