I have been asked to provide electricty to a portable trailer. There is a 277v/480v stand up section aprroximately 300' away. The trailer comes equipped with a 120v/240v 125A electric panel just feeding general lighting/power with the biggest load being the air conditioning unit. I tried to size the transformer to a 37.5 kvA and pull # 4 wire Is this sufficient to allow for the voltage drop?. In the conduit can I pull two hots, a neutral and ground, or do I have to sink a ground rod next to the trailer and land my conducter on terminal XO?
A nod in the proper direction will be greatly appreciated. Thanks!
