great, my only dilema is that,one of the breakers is a 150 amp thats protects the load center which calculated load is 150 amps, Im still not sure if I need a 200 amp breaker for the calculated load of 150 amps or I can use the existing 150 amp breaker ,if I need to upgrade to a 200 amps breaker ,I went to different suppliers and they told me that squared D never made a 200 amd breaker (not main breaker).any suggestions?

I'm sure you won't find a 200 amp breaker to fit in your panel


I just had this conversation with a supply house in that even if you can find a breaker, the bus is not rated for more than 125a. Any larger would require feed through lugs. I did not have an answer for him except to check listings in particular cases. Is there a code that says so, or is it case by case?

If the calculated load is equal to 1.25 x continuous load + non-continuous load , the 150 amp breaker does not need to be changed out.

If it is possible you may consider moving one or more loads out of the "sub-panel" into the main panel. This is how I get by with a smaller "sub-feed" . Sounds like one item could do it a dryer or range.
