I define a LINE side tap as on the Utility aka LINE side of the main service disconnect.
I define a LOAD side tap as on the customer aka LOAD side of the main service disconnect, usually back-feeding a breaker on the opposite end of a bus bar and using the 120% rule.
I have a simple situation that is confusing me regarding a LOAD side connection on the customer's side of a 400Amp disconnect. This disconnect then feeds a 200Amp Main Breaker Load Center and there is space to use multi-tap connectors after the main service breaker to tap into the conductors on their way to the breaker panel.
I used to think this was not allowed. I would always require utility shut down and tap on the LINE side of the main service disconnect and treat our Solar AC Disco as a new service disconnect and bond N and G there. I know that if we tap after the main service disconnect, we would not bond N and G in our PV AC Disco.
What code sections are applicable to this scenario? 705.12(1)(b)?
What does the code say about the ampacity rating of the conductors feeding from the LOAD side of the main disconnect to the breaker panel.
What would be the changes if the main breaker was 400A in the breaker panel?
Below is a simple drawing. Option A is LINE side and Option B is LOAD side.
thanks for any insights
