We are upgrading our electrical panel mounted on a power pole (Manufactured Home) 200 amps currently to 400 amps (single phase) to accommodate a 200 amp line underground to our newly constructed shop/barn. We already have a 200 Homeline breaker box in the shop What we are looking for is a outdoor panel with meter base with two 200 amp mains. One to feed the breaker box in the home and one to feed the breaker box in the shop/barn. What do you have and or recommend?
Asked by: Tetherow
My home and shop are 200 feet apart and I wanted 200 amp service to both places so I installed this panel in between the two buildings. In this panel you have two connections for 200 amps. One is by its self and the other feeds the circuits, breakers, below the lower 200 amp breaker. Now the top 200 amp breaker feeds the home and the lower 200 amp breaker feeds my shop along with the pump house, RV pad and a few other outdoor electrical needs that I have. In order to have the 200 amp service in my shop I needed to add another 200 amp breaker, in series, with the lower 200 amp breaker. So now I have three 200 amp breakers in this panel. What?! You have three 200 amp breaker in the same box? Isn’t that 600 amps? No, still 200 amps to each location. As long as the Main breaker is in series with the other breakers you are legal. My panel passed L&I with the first inspection. :-) Also this box makes hooking up an outdoor generator a breeze.
