250.104(A)(1)(1)

[Ravenvalor]

Based on 250.104(A)(1)(1) would it be code compliant if I terminated my #4 solid copper cold water bonding conductor in the meterbase outside instead of the service disconnect inside which is directly behind the outside meterbase, on a single family residence? This is an existing home and it would be easier to install the conductor outside.

Thanks for the help.

Yes that would be code compliant however many utility companies do not permit the connections in the meter enclosure.

I do not believe that would be a problem with Duke Energy here in NC. Thanks...

IMO when permitted it's often a better place to connect it. Just out of curiosity why #4 solid? Isn't that pretty horrible to work with?

 

[roger]

It is fine in NC and is the best place. I second Infinity's question, why #4

The connection is required to be accessible. Normally a meter base is not considered accessible as POCO has it sealed?

#4 solid is the only wire that I have ever used for residential cold water bonding systems. Since it is bare I do not have to be concerned about damaging the insulation.

True, but in NC it is rare to NOT see it terminated in the meter bases on residential

Around here no one uses solid and since it's not required to be insulated damage to the insulation is not a concern.

And what about the other connections?

I must say I always hated to be called out in the middle of the night because someone's GEC connection came loose.

It is accessible

Accessible (as applied to wiring methods). Capable of being
removed or exposed without damaging the building structure
or finish or not permanently closed in by the structure or finish
of the building.

Here, we're not allowed to land GECs in the meter. That's a shame, as it's the perfect place for driven rods.

 

[Buck Parrish]

Most of Indiana you're not allowed either. It's a shame because the grounding lug mechanism in the meter is made for the grounding wire much better then the neutral bar in the panel.

I've always used #4 Solid for a 200 amp service, too. I don't know why. Should I switch to stranded?

Should I switch to stranded?

I've used stranded on probably 99.9% of the services I've done regardless of size. It also means you don't have to carry material that can only be used for one purpose.

Same here, I've never used solid for a service. For a 200 amp service like in the OP we would use #2 Al for the water pipe and #6 copper for the rods. Added bonus you can use phase colors if that's all that you have on the truck.

Wow. The differences in places is amazing sometimes...
I’ve never used stranded to the ground rods for a residence,
and don’t think I’ve seen but maybe a handful that weren’t solid...
Most are #6 solid.

When we changed over to the TWACS meters, many older houses didn’t have ground rods. Because we really needed them for the meters to communicate properly, those people got two free ground rods driven at their service compliments of the POCO, with #6 solid.

Around here MA & CT I have never seen one go to the meter socket. POCO doesn't allow it. I always use #4 stranded. The only solid I have seen used is #8

With the protection requirements for smaller wire I usually use #4 on anything below 200 amps

It is accessible

All meter bases are not considered accessible. Refer to 250.24(A)(1). Also , which I realize is not technically enforceable, but interpretations can be based on Handbook interpretations, refer to exhibit. 250.8.

According the the NEC definition in post #11 sounds like if could be considered accessible.

So I ask again, if for some long shot reason a meter base could be considered inaccessible why are the ungrounded and grounded conductor connections not required to be accessible?
