600 AMP Service

you need to ground the cabinet , yes. In my area the neutral conductor is not bonded in the cabinet, it just passes through straight to the main panel or disconnect and is bonded at that point. So i would run a egc to the cabinet to ground it. It doesn't need to be a 2/0 though .

I don't think you will need a ct cabinet, they make a 600 amp self-contained meter

If you plan on doing that, you must contact the serving electric utility to see if they will accept that size self contained meter, we do not. :smile:

Most places ground everything on the line side of the service disconnecting means to the grounded conductor. I do not see it as a violation to do otherwise but the fault current return path is now a bit longer is done in that manner. :)
 
I will need to check with POCO on their prefered method of bonding. You fellows cleared these questions greatly. I should be O.K. with PVC between CT cabinet and main panel?

PVC is fine. As long as the bonding and grounding is following the NEC, I don't see why the serving electric utility would have a problem with your methods. :)

This too may be up to your respective utility and AHJ - my POCO and AHJ will not allow PVC. All SE conductors are to be in RMC unless under grade in my area, others too may be simular. Just about all POCO's will publish thier rules, as will most AHJ's.

If you're asking about running #2/0 conductor between the CT cabinet and the the panel the answer is no. You bond the neutral to the CT cabinet and bond it again to the panel containing the main. Installing an addition #2/0 between the CT and the panel creates a parallel path for the neutral current.

Rob,

Sorry to dig this back up but I have a similar situation and is applicable to this thread. I have three separate cabinets, in the center is the tap section, on the left is the CT, and on the right is the service disconnect all laid out in a U formation. The neutral and grounding conductors are connected in Tap section and in CT ( No neutral float) and then the MBJ was not installed in the service (main) cabinet. I said they must install the MBJ. Also, all connected together with RMC and bond bushings installed.
