I'm sure this is an easy one, but I've never sone a service like this, so I am asking. I have a 200 amp service for a single family dwelling. I want to run two 40 circuit panels from this service, but with each panel being able to support 200 amps. The transfer switch can't be double lugged, so I am making connections in the trough. Is this even legal? If so, do I have to mark the panels with circuit #'s 1-80?
