Welding Cable
Welding Cable
(OP)
Hello,
I'll preface this by saying that this is in one of our old powerplants, so it is exempt from the NEC but I do believe that we should adhere as much a possible.
I have found an installation of a feed from one panel to another, that welding cable was used. It is in steel conduit, is #1 copper, and operating at 480V.
If this was not in a powerplant, would this be allowed by NEC?
Thank you in advance.

BUT for a Non-NEC power plant, have you considered locamotive cable? I saw it used in a small plant and started using it myself in small power plants. It is a tougher cable, both the insulation and the wire stranding and is available in much larger sizes than welding cable.

That is, 353 MCM is a tight fit in 500 MCM connectors.

One feature of loco-power cable is that it is readily available as (UL) RHH/RHW, satisfying the code aspect. It's stranding is much finer than the usual "building wire", i.e., more flexible, but is not as fine as welding cable.
