My specs on a particular job call for me to use 12-5 type SJ cord for my connection from the J-box to the suspended fixture. There will be 2 - 277V circuits, with seperate nuetrals. My question is, am I violationg the voltage restrictions of this 300V rated cord? Obviously, there will be 480V in the cord, although each hot and nuetral conductor is only 277V. Which voltage do I go by?

How about a different twist. 400.7(B) requires attachment plugs for cords supplying fixtures. I have never seen a plug that woul match the required configuration.

They are on different phases, hence the 480V.

I think I must recant. I am thinking the wires inside are rated 300 volts but it is probably the whole assembly that is rated 300v. If that is the case I say no go.

Why not put them on the same phase.

You need 600 volt cord and that will not come in plain old SJ.

You need to RFI the EE about this.
