RV Park Wiring

RV Park Wiring

RV Park Wiring

(OP)
I have been tasked to design the electrical system for a small RV park. I'm planning on using RV pedestals that are 240/120VAC, 125A with 50A 2-pole, 30A 1-pole, 20A 1-pole breakers and receptacles on the pedestal. My question is can I feed (loop feed) six of these pedestals from one 200A breaker even though the pedestal is rated for 125A?

9600VA x 6 =57.6KVA
57.6KVA X .6 = 34.6KVA
34.6KVA/240V = 144AMPS

Pedestal have loop feed lugs on bottom for up to 350 kcmill.

Thanks in advance.

RE: RV Park Wiring

You'll want to get familiar with Article 551 in the NEC and then talk with the folks who provide these pedestals.

I understand Article 551.  I'm just a little confused about the tap rule.  Once my 3/0 cable leave the 200A bkr and lands in the first 125A pedestal lugs, then the 3/0 leaves the pedestal (via lugs) for the next pedestal and so on. (see attached) Once the 3/0 leaves the first 125A Pedestal does this make it a tap?  The Mfg. told me I could do this, but I'm not clear with the code.
