Cabling in Refrigerated Warehouse
« on: July 20, 2018, 11:38:12 AM »
We have a customer that needs us to cable some WAPs in a food distribution warehouse. Part of the facility is, for a lack of better words, a huge freezer. It has 30' ceilings and large isles where they can drive forklifts around. This part is kept around 0° Fahrenheit. The installation temperature rating of our cabling is 32°-140°F.  Will we be okay since the boxes of wire will only be in the freezer for a couple of hours?

I would appreciate any helpful comments on this. I'm from Florida and have never installed cable below freezing, much less at 0°.

Ed will probably chime in on this but, possibly indoor/ outdoor CMX rated cable might be a possible choice.   The jacket is thicker and it seems to be more flexible,   Almost rubbery.

I would check with your cable supplier to get the correct cable.

A hundred years ago (OK, 200 years ago!) I cabled National Cold Storage in NYC. It was pre-interconnect and we were installing an Intercom and PA system. We used indoor cable (22 gauge stranded multi-pair intercom and 18 gauge speaker cable).

My experience: Everything was fine till a hi-lo hit the cable and then it shattered like glass.

I would install conduit in the freezer part.

You're using Florida cable. This- THIS is what want in a freezer Good down to -58 Deg F.

Indoor cable will shatter like glass. We have that problem here with storing cable in our trucks over night. Even in the 20s you have to bring it inside and let it warm up for an hour or so or it will crack when you pull it out of the box.

Nice looking stuff, Hal. Didn't exist in the '60s and '70s, though...
