with a 400 amp resident service, not sure wire size, never did one before, would 2 3/0 paralleled cables per phase be enough in 2.5" rigid gal be acceptable for a mast entering the meter pan, then use 2-2" sch 80 with 2/0 se cable
one for 200 amp house panel and one 200 amp brk disconnect for a garage panel. i would use #2 gec to the water main and #4 from the panel & disconnect to bond the panels to #2,and #6 ground wire to the ground rod.
