Tapping Meter downstream to Two Mains

Thanks, I think it's actually going to be more like this:
Am wondering how to size the groudn from the wireway to the CT cabinet?

Is there a ground from the wireway to the CT cabinet? Wouldn't you just bond it to the neutral since it on the line side?

You can either bond the CT cabinet directly to the neutral/grounded conductor, or you can run a bonding jumper to the grounded conductor somewhere else, such as the service disconnect. I would just do the former, unless there was a reason to use the latter method, such as a local rule or objectionable current.
 
Because I'm grounding the wireway which is ahead of the service disconnects and all equipment have to have egc's.
But yeah the neutral bonding seems like the way to go there.

The EGC's do not begin until after the point where the MBJ is installed which is in the service disconnects. All metal parts and equipment on the line side of those service disconnects are bonded direct to the neutral. The EGC's depicted on the sketch are parallel with the neutrals and will carry neutral current.
