I have to do a 400A CT metered service that will have two separate 200A service disconnects in separate enclosures. The POCO has the following rule:
Ok so it appears I need to bond the CT cabinet to the neutral conductor(s) in the service disconnects. I am not seeing anything in the code that directs me how to connect the SSBJ to a service with multiple enclosures. 250.92(B)(1) just says to bond to the grounded conductor. My instinct tells me to run a SSBJ from EACH service disconnect enclosure's grounded conductor to the CT cabinet,effectively just treating the grounded conductors like they were parallel conductors, even though they are not. Do others agree?
Connection to the grounded service conductor (neutral) must not be used to bond current transformer enclosures. Bonding must be derived from the service main grounding point.
