Hi all

I am doing a job on a kitchen remodel and the home owner wants me to move his metering cabinet etc.

The 800 amp CT Cabinet does not have a disconnect that I am aware of. There are some small switches underneath the actual meter in the meter socket.(Can these be used as disconect?)

I believe it is a Erickson 283-1

I need to move the cabinet roughly 300'. (350 mcm wire)

My question is, and I am pretty sure I will have to do this is. Will I have to buy a new CT cabinet with disconnect to satisfy the code on distance between panels and meter socket. Will I have to bring the grounding electrode conductor out to the new meter location?

I was planning on running 2- 3'' pipes from main disconnect inside the building 300' to the new meter location (the distance now is 12" and still no disconnect outside).

Some help would be appreciated.

Thanks
 
This is a picture of the Erickson part you described. Not sure what it is but it is 3 phase and I don't see any switches..:confused:


I googled the part number and this is what I got.

No. And, don't touch any wiring between the CT cabinet and the meter while the service is energized.

Not exactly. You might not have to relocate the CT cabinet, and maybe or maybe not the meter. You will need a disconnect where the new conductors enter the new point into building.

The interior disconnect will become a secondary one. Yes, you will need to relocate the electrode connections to the new disconnect. You will also have to keep separate neutral and EGC conductors from the new disco all the way throughout the entire premises.

Whether the new disconnect needs to be before or after the CT, if you relocate it, will likely be up to the POCO to determine.

Added: You really need to contact your POCO's field engineering dept. That's what they're there for.

The small "Disconnect switches" are probally the CT shunts, these short the ct's so the meter can be removed safely. Definetly get with the POCO engineers as to placement and requirements. A- Your breaking their seal which can land you in jail B-They can refuse to reconnect power if it's not the way they want it.
 
Thanks Larry

I did not touch any of the wiring...just viewed.

The meter is attached to the front of the cabinet. The homeowner wants to move the whole thing for aesthetic reasons. I was thinking I could take the pipes that go from the interior main disconnect to the CT outside and extend them to new CT cabinet/meter location. If I still need to put a new main disconnect at point of entry then I wouldnt be satisfying the homeowners aesthetic needs.



"The interior disconnect will become a secondary one. Yes, you will need to relocate the electrode connections to the new disconnect. You will also have to keep separate neutral and EGC conductors from the new disco all the way throughout the entire premises."

By this I think you mean I need to run the EGC separate from the nuetral to the new main disco and the secondary main disconnect would essentially become like a subpanel and main bonding jumper would be at the new disco location?

Forgive me but I havent heard the acronym POCO but I assume it means the Power Company? I had them come out but the general contractor talked to them because they didnt come when they said they were going to.
