I built a pole builing next to the house I would like to up grade to a 200 amp. service to the garage and then run 100 amp from the garage back to the house. This will be all under ground in 2 inch conduit. The service will be moved to the garage also. Will this be aloud and I am thinking of running phone and cable the same way. also in a separate 2 inch conduit. does this sound good.
