This electrical panel was likely constructed by seebees. Cut up sections of ground rod are used for electrical bussing and the feeder conductors from the generator are bolted on the ground rods. Branch conductors are then taped or wrapped around the ground rods to feed housing, lavatories and what have you. Check out the gas cans used to prop this baby up. The voltage across any two bars is anywhere from 230v to 380v. Imagine falling on top of this accidently! Optional cover is shown installed.
