I installed a meterbase with 100 amp mb panel pvc nipple between them
fed it with 3 #2 cu underground
2 ground rods with #4 cu to neutral lug in meterbase
installed 3 #2 between meterbase and mb panel with bond screw installed
failed inspection inspector wants #6 green between neutral in meter and ground bar in panel
am I missing something

Is there a bonding jumper in the panel?
 
I think the question is "if the grounding electrode conductor is landed in a meterbase, and the main bonding jumper is in the adjacent main panel, is a grounding conductor or bonding jumper required between the meterbase and the main panel?" The OP describes the meterbase and the main panel as being connected via PVC conduit containing two ungrounded conductors and a grounded conductor, no grounding conductor.

The installation is compliant. Adding the #6 would place an additional conductor in parallel with the neutral and be a violation.

If that's the question then as Don has stated the additional EGC would be a violation and is not required.
 
bond screw

bond screw

I mentioned to the inspector that the # 6 would be in parallel with the #2 grounded conductor
yet he was set I was going to do it
iv learned not to argue to much
I did take the bond screw out though
do you think I was right

I would argue because he's obviously wrong but if you don't want to do that then as soon as he left I would remove the violation that he told you to install.
 
That doesn't sound right. Normally after a meter there is only 3 conductors ; 2 hots and your service neutral. After the first disconnection point ( which would be your panel ) it is now a feeder requiring 4 conductors; 2 hots 1 neutral and 1 ground. You should have a ground rod for the meter base, and a ground rod for the panel. They are normally tied together underground, never through the enclousures. Put the bonding jumper back in, you are required to have the ground and neutral bonded in that panel box. If this panel has another set of lugs, and you intend to feed another panel just remember that it is now a feeder and will require 4 conductors.

If you take out the bonding jumper and if there are both a neutral bar and an equipment grounding bar, and if the jumper from the meter lands on the EGC bar, it would be code compliant.

Isn't it required to bond the service neutral to the enclosure that contains the service disconnect, in this case the panel?

Honestly brother, I don't think so but its in your best interest to just add the 6" grnd. Never try to undermine an inspector because they can make life miserable!

Tell the inspector to give it to you in writing so that when someone in the know ask why you did it you can show them an uninformed inspector made you do it.
