Hello Wayne, Seems to me like the AHJ is asking for the bus bar rating of the main load center which is usually printed on a sticker inside the panel (only visible with the dead front removed). Then he also wants the rating of the main breaker that is installed to protect the panel (read right off the breaker handle usually). >From there he can determine if what you are back feeding is proper.
Best of luck.

I have an AHJ asking for the service panel buss rating and the service panel buss protection rating. Am I correct to assume that the rating is the service panels designated rating x 1.2% (ie 200A x 1.2 = 240)? and that the buss protection is the combined input breakers? 200 Main breaker + 40A solar back feed = 240A? Given that there are many different size panels (150A and 200A) that share the same bus, I have a difficult time believing this to be true. If there is any designated signage or data sheets specific to the service panel, where might I find this? I have looked at Schnider but have not been able to find anything specific.
