Clarify what you mean by 'No main breaker', though. If there is a 30amp double-pole breaker set for EACH of these sites, in a Main Utility Panel on the property, I would guess, where then is the 'MAIN BREAKER' for all of these?

Yes, main breaker at the distribution panel. No main at the ped. Just 1 30 and 1 20. However, because of the distance and voltage drop the wire size should be a minimum of 1/0 at least just to get 30 amps. It is not. It is # 4 ALM and therefore I must use an autoformer on a 3 year old system. 116 volts with no load just don't cut it!
