I had a 200A Main Service Panel in my single phase dwelling unt. It had 1/0 cu wire for the two hots and neutral. (should have been 2/0)
I had the main breaker replaced to 150A so that the MSP can accept a load side connection for an interactive solar system. For the load side connection, the bus rating is 200A, main breaker is 150A. Load side connection is to be in accordance with 705.12(B)(2)(3)(B) - and going by that it should be able to accept a backfed PV breaker of 90A. (200A X 120%) - 150A = 90A
Question is that feeder wire now good at 1/0? Or should it have been changed to a 2/0 wire?
