Code Question Of The Day

Monday, January 23, 2012
Question:

Subject: CQD - December 15, 2011

Hi Charlie,

Would you send some of that warm weather from Chicago up to Wisconsin? A comment for CQD 12/15/2011. Your response to Question 1 is right on. The cord is required to, as they say in 400.8 not be run through or located above suspended or dropped ceilings. In response to Question 2, there are a lot of low voltage transformers for security and other applications that plug directly into a receptacle outlet and then have Class 2 wiring from the transformer running to equipment in or below the suspended ceiling. This does not appear to be a violation as long as the space above the suspended ceiling is not a “Other Space Used for Environmental Air.” Keep up the good work and stay warm.

Answer:

Hi Bill, thanks for commenting. There is no NEC requirement that prohibits installing a receptacle outlet in a suspended or dropped ceiling. NEC 400.8(5) prohibits a flexible cord from being permanently installed where located above suspended or dropped ceilings. I think we have run his one to death. Let’s get on to other subjects.
