my friend has a 200 amp breaker box in his basement fed underground with
2/0 copper and a 200 amp meter base. can i connect to his line side of his
breaker with a 2 lug splitter to feed a 200 amp box in a outbuilding. the
splitter i bought is from a electric supply store and is rated for a dual
transformer connection?
I would say no. You have a 200 amp feed. You cannot fuse it for 400
amps. What you CAN do is feed the outbuiulding with a 100 amp 220
breaker in the first panel, and a 100 amp panel in the outbuilding.
