Re: meter with neutral bonded to frame
I think you may have left out the letter "T" in "CT"...or at least that what I think you are talking about.
In regards to your question, in my opinion running an equipment ground before the service disconnect is a violation of 310.4, unless they are the same size. Think about it...you bond the nuetral and ground at the service disconnect, and the nuetral will be bonded to the CT can along with the ground. Nuetral and ground are one and the same on the supply side of the switch.
