Hello fellow Forum members,
I know the NEC limits flexible cord use to 90 days for Christmas Decorations, Carnivals, etc, and for the duration of temporary construction or work, but there is no other place in the NEC that limits how long they can be used for connection of portable equipment, and the other allowable uses. I know the NEC states that flexible cords and cables shall not be used in lieu of permanent wiring, but if an extension cord is being used for one of their acceptable uses, where in the NEC does it states for how long that extension cord could be used? I've read multiple comments stating that they have seen extension cords powering portable equipment at an industrial plant for over 5 years and that that is not acceptable, etc, but the NEC would not prohibit that.. or does it?
Thanks everyone!
