Comparison of using THWN to RHW

[natfuelbill]

I have to decide whether to go with the THWN or RHW (both will be 350kcmil). Any thoughts? The raceways will be a combination of Robroy and cable tray.

What is Robroy?

among other things they make plastic coated conduit. i am guessing that is what he is refering to.

you can even send them your own fittings and they will coat them if they don't sell what you want.

Will the alteration void their listing?
