I'm running the service for my trailer and I need some help with it. I have a 200 amp panel in the home and a 200 amp panel on the pole. But the panel on the pole only has one set of lugs on the top of the main breaker. Do I need lugs on the bottom of the panel to put the wire in from the trailer to pole and use the lugs on the top to go from the outside panel to the meter?
