I was thinking you said 'by mistake they ran a #6 to the CEE" that the CEE was rebar. According to table 250.66, typically for a service smaller than 200 amps the bonding jumper or GEC to the rebar CEE could be smaller than #4.

Gotcha / I understand.....Sorry, it was the way I worded that post. One would think after all these years I would have learned how to type. Thanks Trevor.

No problem. I wasn't trying to high jack this thread, but i did have an inspector insist that I needed a #4 to the rebar on a 150 amp service.

That's a common erroneous requirement, from what I've seen.

Well I can see why. 250.52(3) and 250.66(B) just mention a minimum of a #4 and not larger than a #4..........Where does it break or draw a line between 100 amp or 200 amp on CEE, or as GEC are based on SE size 250.66? CEE is a minimum #4 cu the way I read it.

That's if you only use 20' of bare copper conductor to make a CEE. If you choose to simply attach to the rebar then the bonding jumper or GEC is sized according to 250.66. A typical 150 amp service with #1 or #1/0 copper service entrance conductors would only require a #6 bonding jumper or GEC to the rebar.

Perhaps he had 250.64(B) in mind. #4 and #6 are treated differently as far as protection. Just a WAG. :grin:

How come the POCO would require the meter socket to be 4' to 6' off the ground, when an underground pedistal places the meter about 3' up.

John when it comes to something like power company meter heights I will not listen to anyones opinion.

I go right to the power companies Green book usually available to anyone on line and get a definite answer in writing.

Even what the power company employees will tell you is wrong many times.

Most power companies have preferred heights but have exceptions for things like meter stacks that may have a meters from 15" to 78" AFF.
 
see that is what is confusing me. We dont have "meter maids" anymore. Nstar switched to the digital meters so all they have now is a guy in a car driving around and he has a computer that picks up the readings so the person does not have to get out at every car. Kinda cool I think :grin:

Right from Nstars own book

A clear area of 3 feet is required in front of each meter.(See Sketch 13)

Installation On Pedestal
For residential and small commercial applications only, the installation of the meter socket shall be permitted to be mounted on a free-standing pedestal pending the approval of the authority having jurisdiction.

Protection wasn't an issue. The #6 was run with and secured to the building surface.
