Does anyone see any violation with the following installation?

I have a 75KVA transformer the secondary feeder hits a 200 amp within 10' and is fuse at 175amps. Then leaves the disconnect in an existing 1.5" conduit underground with (3) 2/0 thhn and (1) #6 grn., then hits a jbox and is tapped with 2 feeders each (1.5" pvc with (3)#3 + (1) #8 grd). These feeders are located outside which feed a double wide trailer that has (2) 100 amp panels fused at 100amps.


My biggest concern is the 175 amps is more than enough for the load being served, but am i fine with the panels being 100amp mcb?

Sounds like it could meet the code requirements for an outside taps of unlimited length.

Yeah thats definately true i was just worried about the panels adding up to 200amp. considering that there fused at 100 amps each and the feeder being fused at 175 amps.
