First of all, it is my understanding that the wireway section of a meter bank is considered a panelboard. Based on this, is it OK to splice the SER cable inside the wireway? We've got a 40 unit apartment building and each unit is getting a 1.5 kw PV system. Each unit is metered separately with its own 125 amp breaker. I want to tap each apartment units main breaker to feed the PV. I'm doing this instead of backfeeding a breaker in each apartment because of voltage drop and monitoring concerns. I plan on doing this with Polaris lugs. Does anyone see any cause for concern? I'm working on getting the fill calculations right now to show the inspector.
