We have 4 heaters in a commercial building. These heaters draw about 4 amps and have 3' cord and plug, there is no provisions for it to be hard wired.
I would like to run emt above the heater to 4 square box. From out of that box I would like to drop SO cord, 3'-6' in lenght, with a strain relief connector (kellum style) at the 4 square and a SO cord receptacle at the other end to plug the heater in. Is this legal?
Hrm, I would of never guessed an extension cord. I get a bunch of residential rental home repair work that calls for removing of extension cord. This is typically a fridge or TV in the basement a tenant has ran an extension cord to and I need to add a receptacle for it.
This could be just because its a rental property.

Cord for connections to equipment has been an unending debate.
The usual solution for 'cord drops' is a twistlock receptacle within a 4x4 box at the bar joists; a strain relief on the cord, and a suitable cord cap on the end of the cord. The equipment supply cord plugs in.
IMHO, the above is compliant.

Interesting question. What about a bell box with threaded entries? Those pendant cords, with twist lock plugs were pretty popular in fast food joints to serve equipment that they rolled around to clean under. I just never had a reason to see what was above the ceiling. (I was "data" in those days)

Greg: Equipment that requires 'moving' for sanitation like fast food locations has been using: Suitable box mounted face down in ceiling with a receptacle in the box, a cord cap w/strain relief with a female cap. The equipment is connected to the 'hanging' female cap.
There is the same setup in the pharma/HABA facilities here for sanitation and 'line swap' reasons.

I got the impression that our fire marshal was not allowing any "extension cords" when we were working in computer rooms. I know I had a customer with some cords made up with SO and Russell Stoll connectors on each end. They got tagged. The customer ended up having to move the fixed in place receptacles whenever they moved the equipment.
