Kind of getting confused here, ok say if I have 2 ground rods and gec going to meter enclosure bonded to neutral, and 3 wire se from meter enclosure to main disconnect panel in basement, and another gec from water pipe to panel bonded with neutral. I have the 08 handbook and the way I read it and looking at pics , I am getting mixed feelings, right and wrong.

Also say you have 2 ground rods and gec going to water pipe and then main disco bonded with neutral, and also a gec from meter enclosure bonded with neutral back to main disco. Do you feel these are problems or violations?. I would appreciate any info or thoughts thanks.:
 
Situation 1 sounds o.k.

I can't actually follow #2.

Your gr el conductors can attach anywhere between the servie point and the 1st disconnecting means (250.24{A}{1}) and they do not all have to attach to the same location, if that helps.

Just think of it as a meter base combo and treat it the same. It's all service equipment.
Until it leaves the first disconnect.
 
I always thought that you could only bond gec and neutral at main disco. So you can bond gec to neutral multiple times before and at main disconnect ( meter enclosure, and panel with main disco) as long as it is not bonded after main disco. Hopefully I'm getting it
 
I saw the pic similar to the one in the soares book I have, thank you, I was wondering if I was correct and by the pic it looks like it can be multiple spots before main disco. Thanks guys

No, because I've never worked in Stamford, Hartford, New London, Willimantic and Waterbury. That's where you need them for some reason. :confused:

The last job I did had a 208/120 service, single phase, and that meter needed one, the thing is I ordered the part from EW and it only came with a bracket and two screws, so I installed it just assumed that it was bonded to the meter enclosure, got a call from CL&P saying the 5th terminal wasn't wired... :) guess it wasn't bonded. :roll:

You think millbank would make a kit that included everything to do the job? Now I have to have a bucket truck back out there to disconnect the service again...

Was that service in the city? For some reason the green book lists those places as needing it.

No, northwest corner (right next the the mass border), the reason it needed the 5th terminal in this case was the 208 voltage.

Hey, I just looked the part # up at Millbanks site, and I should not need the neutral wire, so somebody is wrong. :)
