400-8

[mike anchondo]

I have been requested to provide a 15-R outlet above a suspended ceiling (non plenum) for a wireless network transmitter. It comes equipped with cord and plug (hard wiring it, is not option). While 400-8 (5) does not allow cords and cables above a ceiling, it does allow them as specified by 400-7. I contend that this equipment meets the provisions of 400-7 (8) and installing an outlet for this equipment to plug into is OK.
Am I right?

Re: 400-8

I think you are okay with your interpretation of the code. I read 400.8(5) as pertaining to branch-circuit wiring and not cord-and-plug connected equpiment. If in doubt, ask your local AHJ.

Mike,
I think that 400.8(5) says you can't make this installation. The code's intent, in my opinion, is to prohibit cords of any type above a ceiling. As Bryan said, check with your AHJ.

I agree with Don, cords are not allowed above a suspended ceiling. This was clarifed in the 2002 NEC as there was still issues with cords above suspended ceilings. the reason cords are not allowed above ceilings is they are a temporary wiring method and have to be visible. I have seen many applications of portable cords after about 15 years the insulation is hard and cracked.

I agree with Bryan, Don, and Tom. (this is twillight zone material)

Our AHJ's will nail LV contractors every time.

To add to the mosaic, it would get shot down here also on the basis that the others have stated.

Re: 400-8

Thanks to all for your replies. What throws me is the first statement in 400-8, "unless specifically permitted by section 400-7, flexible cords and cables shall not be used for the following":

My contention was that the piece of equipment met the requirements of 400-7 (8). This "appliance" is designed for ready removal for service and is identified for cord connection.

What if I mounted the unit inside of an enclosure along with an outlet for it to plug into? Rational being if the cord connection is considered a fire hazard it would be contained. My customer does not want the unit exposed to public, both for security and aesthetics.

Re: 400-8

Mike, as a networking guy there may be another solution to this issue. If this is an access point type of wireless network transmitter, connecting a wired network to a wireless network, then many models have another way of being fed power. If you are not allowed to place an outlet above the suspended ceiling, possibly a different model access point that can handle Power Over Ethernet (low voltage power sharing the data lines) could be used. This would put the power adapter where the networking cable terminates.
If this is not an access point, and only a wireless re-transmitter, you may still be to just make a custom cord and extend the low voltage above the ceiling until you get to a wall you can place an outlet.
