I am working in a municipality where I have not worked before. The AHJ is a generalist without Electrical as his main discipline. Asking him some specifics about the electrical permit application has led to some reasonable (general knowledge) answers that have unreasonable (specific electrical knowledge) implications.He is a really terrific guy and I love working with him, so this is not a dig at the AHJ.

However, I still want to complete the application in a thoughtful way. How would you interpret lines 10-12 of the application? I'm thinking this is the size of the first means of disconnect. Thoughts?

That's my guess too. The AHJ was not clear on this. He seems to accept what the contractor puts in the application.

Service switches have a distinct definition in the NEC but often people use the term to describe something like a disconnecting means which is not a service switch. Given the way the application is written IMO this is for exactly what it states, a service switch AKA a service disconnect.
 
Sticker shock !!! The total electrical permit fee for most houses here is less than $200.

Wow. Just to replace my service and add a sub-panel here was over $200. A water heater replacement was $181. A new house is probably +$5K.
 
Our building permits are more along that line but a 200 amp Rough-In or Final in the State is less than $50.

Hmmm... It's a sensible definition, but I cannot find it in Article 100 nor in the body of the 2017 NEC (Currently in force in Wisconsin). Maybe in 230.71 where there is a limit is six switches to disconnect the service. Regardless, in context that has to be what it means.

I really appreciate the engagement @everyone.
