Pedestal feeder verification

[Learning Always]

Customer wants 4 50/30/20 rv pedestals installed on private property for family members to utilize. Based on 12000 va per site (551.73) and a demand of 75% ( table 551.73A ) I come up with a calculated load of 150 amps. Plan was to use the feed through lugs on a 200 amp sq d main breaker service panel and daisy chain a 4/0 USE aluminum feeder (rated 180 amps) through each rv pedestal protected by the 200 amp (240.4 B) main breaker in the service panel. Besides voltage drop which I have already calculated is not an issue, could any of you bright minded people verify I havent missed any details? I have learned alot from this forum I would appreciate any feed back you guys are willing to offer. Thanks

Watch 551.72(D).
Sometimes cable assemblies have reduced neutrals.

Thank you for the heads up. The wire I have sourced is a quadruplex 4/0 4/0 4/0 2/0.
