    You most likely cannot put a 150A branch circuit breaker in those panels. I bet the max is 125A.

    You also CANNOT tap off the main lugs with another wire. This is a BIG no-no.

    I'd look for feed-out lugs that snap onto the buss. I am not sure if they are available for CH series. Then you can attach the conductors to that and feed a 150A disconnect near the panel.

    What about all the other codes involved with this? Are you up on them?
    Are you the electrician doing this job?
