The service for a house I'm working on has two 200 amp load centers next to each other. One was originally installed to provide future power for a shop, the homeowner is now ready to run power to the shop. This load center has a 200 amp main breaker and supplies SE-R 3/C 4/0 + 1/C 2/0 that runs through the attic to the other side of the house and ends in a box, that may be too small, on an exterior wall. We're planning to splice the conductors on the exterior wall for the final run to the shop.
It looks like the 4/0 SE-R should have been on a 150 amp breaker since it's not supplying a one family dwelling. Is this correct?
Options:
1. Replace 200 amp main breaker with 100 amp breaker. - I like this option though the breaker is no longer in production and may be hard to get. The current breaker has a mounting kit. Since I already have the kit could just the breaker be replaced? If I can find one. It's a GE THQMV 22kaic.
2. Add a 100 amp branch breaker. Move the 4/0 to the branch breaker by transitioning to smaller wire for terminating to the breaker. I'm not crazy about adding splices, we typically try to avoid them unless absolutely needed.
Opinions? Other options? Pros and cons? etc.
