I need some help from the technical experts out there. I am an army safety specialist with the McAlester Army Ammunition plant, McAlester, Oklahoma.

Situation: During an annual safety inspection of a facility it was noted that 4 heavy duty flexible cords were piggy backed, connecting a Dayton Air Circ Fan in a Class 1 Div 2 area. We won't go into the last part of that one folks

I had been trained in USAF safety that piggy backing of flexible cords was not permissable IAW the NEC. Once again, we won't discuss the Class 1 Div 2 req's in this msg. LOL I have researched 400-7 and 400-8 which in itself is pretty clear cut.

I was referencing 400-7(b) Attachment plugs. It references 400-7(a)(3), (a)(6), and (a)(8) ... attachment plug being energized directly from a recep outlet.

I don't want to send a customer an incorrect reference without consulting you all. However, am I on track with the way I am reading this?

Please confirm

Thanks folks for your time and knowledge

Re: Piggy backing flexible cords

Ok, piggy backed is what exactly?
And a good answer for portable cords of any type and any location is they are not to be used as a substiture for the fixed wiring of a structure, see NEC section 400.8
Portable cords and the misuse of are a leading cause of fires....
 
Re: Piggy backing flexible cords

Piggy backing is connecting one cord to another from the equipment running back to the power recep.

Your response was the as mine, but there are always some folks that want to challenge every compliance issue that comes up. In some ways that can be good as it keeps the folks providing the info on their toes.
