We are building a small house at a lake that has a 200 amp feed through panel at the meter pole at the street. We would like to install an underground feed to a 150 amp indoor panel at the house. Electricians want to run an SE 2/0 wire. I would prefer to run a 2/0SER RHH,RHW-2.
I believe that would give us a fire rated cable where it enters the house. I believe SE is not rated for burial. Any thoughts or recommendations?
Also, if the 150 amp panel is considered a sub panel, would I need a four conductor wire? A separate ground should be installed at the house.

SE cable not rated for burial.

If using direct buried conductors get a type marked USE and RHW. USE only rating can not enter the building. If using raceway pull THWN, XHHW or RHW types.

If what is at the pole is the service disconnecting means, all circuits that leave that point must have an EGC for new installations. Can be exceptions to feed existing separate buildings with existing three wire supply conductors.
 
Are you proposing using the feed-thru lugs on the service panel? If so your conductors will need to be sized to 200A and the 150A panel will need a 150A Main Breaker that will accept the 4/0 Aluminum (or 3/0 Copper) conductors. Otherwise you will need to put a 150A breaker in that service panel to supply your feeder conductors running to the house.
 
Assuming your original post was refering to USE, you are correct, USE is not rated for indoor use , however, a lot of USE cables are dual rated with RHW listing also.

I believe 240.21(B)(5) Outside Taps of Unlimited Length could be applied here.
150A wires as long as there is 150A CB or fuses at the Building.
 
Yes, I stand corrected....and a little embarrassed! But this is exactly why I participate in this forum. It forces me to discover the things I have yet to learn or understand. I am now spinning up on the whole 240.21 section. Always skimmed over it in the past....never looked close at how it could be applied. Sure enough this situation fits perfectly. Thanks ptsonsparky, augie47, and kwired for pointing me in the right direction. And to Pool guy R, my apologies for the incorrect info.
