I'm looking for retractable cord reels that can be hard-wired to overcome the restriction on extension cords used as permanent wiring. These are to be installed on the ceiling of science labs.

Anybody ever seen such an animal or have any other suggestions for a retractable reel?

Thanks

Ryan

Check out WW Grainger. I think it's www.grainger.com

McGill is one mfg that I have installed, and there are others.

John,


Those McGill retractable worked very well. I used them for block heater in fire engines. We mounted them to the ceiling and used steel cables to restrict the movement of the retractable cords. Sometimes firemen get excited when they are going to fires and forget to unplug the engine block heaters. smile

If a cord is permanently wired, is it an extension cord? I don't think so. Are pendants not allowed? Why can't receptacles be installed on the lab stations?
There are lots of good reasons to use a pendant rather than a desk top receptacle. Maybe the equipment cannot be fixed in place, the trucks would break a floor plug. No wall to install a receptacle.

I assume the NEC has rules governing the use of pendant receptacles which are not considered to be extension cords as 1 end is hard wired. CEC answer in an NEC forum.

"Retractable" is a word that doesn't appear in the NEC so I guess we would call these a pendant receptacle.
I assume if it is a listed assembly, installed per the instructions, all of the rules are covered. (cord type, attachment, strain relief etc).
I do understand the technical violation posed by this being cord and plug connected but in the grand scheme of things it is not something I would go out of my way to cite. I assume it is the fire marshal who is doing this. They are usually the "extension cord police" although the concern may be misplaced in this case. The attachment to the branch circuit is not where the hazard lies, all other things being equal (same reel, cord and receptacle).

Seems like WWG deleted the 'better' quality versions upon a quick look in the catalog just now.

A decent electrical supply house should be able to get McGill & Appleton, or a similar brand.
