Do they make a 175 amp snap in breaker for a load center. I have a situation where this site has a 200 amp panel on the outside of a storage shed. They want to feed a new structure with 175 amp breaker from this panel. The panel now only has 2 outside 20 amp gfi on it now. Do I have to change the load center panel to a 200 amp disconect put a trough then subfeed the two panels ? or change to a panelboard that accepts a 175 amp breaker?

What type breakers are in there now? QPP, QPPH, HQPP, HQPPH, etc?? How many poles? What interuption rating do you need?
Looks at their online Speedfax catalog. Looks like they do:

I'd match the AIC rating of the main. Take the sheet I gave you a link to to the supply house and ask for help or provide the info zog requested to us and see if we can help along with the catalog cut.

Maybe Siemens makes a 175 amp feed-through panel and you can just swap the guts over. I know they make a 200 amp feed-through but don't recall if it's the same size as their typical 200 amp loadcenters. If you can swap guts, that wouldn't be to bad.

I use the 200 amp feed thru all the time. You will just have to run a larger conductor for the feeder.
