Siemens Panels & Interlock

[Little Bill]

I've been asked to install an inlet and interlock kit for a Siemens load center. I haven't been to the customer's house, he just sent me pictures of his panel. I had already began looking up the correct interlock and was "assuming" he had a 200A panel. After looking at the pictures I see that it is a 225A panel. Is there any difference, other than the amperage, between a 200A & 225A Siemens panel?

I finally found where the 200A & 225A are the same bus spacing. Actually, Siemens has a kit. The only draw back to it is you lose two breaker spaces, and if you already have the breaker space tabs broke out, regular filler plates won't work.
