Question:

I need to install 110V and 208V electrical cord drops to equipment. The cords will drop roughly 14 feet from the wireway. We will be installing strain reliefs at the top. I need to know if I need to use a certain type of cord rather than typical SO type cord and if I'll need additional mid-run strain reliefs.

Answer:

Hey Mark thanks for your question. Cord pendants are allowed as stated in 400.10(A)(1) and I have seen much longer SO cord pendants being used without a problem. Make sure that the use of flexible cord is appropriate as stated in 400.10 and 400.12.

The cord manufacturer can probably provide some guidance about length and weight limitations.
