Upgrading old 200 amp service panel, like for like. Unsure of cables to run from weatherhead, through a 2 inch conduit mast, down to service panel. It seems that 4/0 is required for 200 amps. However, local supplier says Sweetbriar URD 4/0 4/0 2/0 is used. I'd rather play it safe and install 3 4/0 cables.
I found a couple of 4/0 cables but am unsure of the differences and want to confirm they meet code. I think the only difference between the RHW–2 and XHHW-2 is insulation thickness.
What would you install? Both are Alcan cables and the price is almost the same.
4/0 AWG, USE-2/RHH/RHW-2, Compact Stranded Aluminum, Black. AA-8030 AL Series XLPE 600V.
or
4/0 AWG, XHHW-2, Compact Stranded Aluminum, 600V, Black
Spec sheets for both:
