VE Options

[Alwayslearningelec]

We have a job in which there a good amount of MI cable but I was thinking of offering a VE option to use conduit with RHH 2 hour rated? Any reason why that could NOT be used? For some reason I'm thinking fire pump must be MI.

As long as you get the 2-hour rating, it doesn't matter what you use. Make sure there aren't any restrictions in the job specs OR buried deep in a drawing note. Being careless can get expensive.

We have had jobs approved using "DuraLife RHH90" 2 hour cable in conduit.

VitaLink is a brand I'm familiar with.

THanks. I have to do the comparison but I think overall conduit and RHH 2 hour rated wire in conduit would be cheaper than MI cable.

What type of conduit? Did you also compare Vita-Link MC?

I don't think they will allow mc cable. Not sure what type of conduit must be used with RHH 2 hour wire to keep it's rating. Sure it's in the docs.

You mentioned doing a comparison what type of conduit would you be comparing? If I had to guess I would say that 2-hour conductors in EMT would be the cheapest.
