Media room branch circuit plug connected?

[PetrosA]

If he wants to do multiple outlets, the cord and plug is out because you can't put a cord cap on a piece of NM and then run it through a wall and terminate it in a wallcase and call it a cord at the same time. If it's an extension cord, it has to be made up of listed parts and can't be used in place of the premises wiring system. If it's house wiring, the romex has to be protected from physical damage, which it's not where it exits the wall and plugs into a receptacle. Smart $'s suggestion for the surge suppression receptacles would be what I would recommend to the customer in addition to a whole house unit in the main panel.

I was thinking the same thing as long as the nothing on the circuit is a required outlet.

Such as outlets required to be installed for wall space under 210.52(A)...???

That's the one I was thinking about.

I'm not so sure about that. While this case is regarding surge suppression equipment, how would it be any different than say connecting a UPS unit? Granted not a typical residential application, but in commercial I've seen UPS units that are cord-and-plug connected. Would you consider these compliant? If we base our evaluation on 400.7, which stipulation allows these UPS units to be cord-and-plug connected? Granted it's not a problem if the unit is listed for cord connection to its supply. But where does Code permit a structure's fixed wiring on the load side to be connected using cord?

Heck, what happens when a building has a 'generator power inlet'? You are temporarily connecting a piece of apparatus (the generator) to the building wiring, using flexible cord.

Yes, but I think that you would have something like this mounted in the wall and connected to the building wiring.

Flexible cord would be used to connect the apparatus to the building wiring, but would not substitute for the permanent building wiring.

Did someone say it was up for inclusion in the 2014?

Well 2014 is already out and adopted in some places - so it is beyond "up for inclusion". It either happened or it didn't:happyyes:

That word "temporarily" in there excludes it from being considered permanent wiring of a structure.

Code Reference

Code Reference

How about OSHA 1910.303a - Which happens to be OSHA's definition of usage for temporary wiring.

Code ref? That's whst I was remembering, but could not cite a number.
