I have also seen that the service equipment(meter pedestal)cannot accommodate a 200A main breaker.In these situations I have installed a 100A breaker in pedestal,feeder installed is #2 URD 4 wire(100A)and considered the 200A breaker in the mobile home panel as a disconnect only ,with lugs listed for #2 wire as a 100A service(assuming the load calculation does not exceed 100A service calc.)Does anyone see any thing not code compliant with this practice? comments please. P.S . This is in a mobile home park.
