Ring/Ringless Interchangeability


I have a 100 AMP load center with a ring. The power company rep says that they only use ringless meters. Am I toast or are they pretty much interchangeable? Is there a way the power company can install one of their ringless meters into my load center box which has a ring?

Sounds like a current transformer. Can you post a picture. I have never seen a CT in residential. The meter goes in a meter base, not the load center. Sounds like you are attempting to use an industrial panel in your home.

It's not a load center. It's a meter box. My apologies. It has a ring. Edison told me they have ringless meters.

They are not interchangeable.

A ring type meter has you install the meter socket cover .. then plug in the meter .. at that point you install a metal ring that engages the rim of the meter and a rim on the cover. Then a sealing lock is placed on the ring.

A ringless meter has you plug in the meter then install the cover. The cover holds the meter in place. This allows you to remove the cover without removing the meter if any testing or servicing is required. Then a sealing lock is placed on a protruding tab at the bottom of the cover.

How do they get a ring on a ringless cover ? The ringless cover has no 'rim' for a ring to attach .. do they just not install a ring ? I realize the meters will fit but I'm not understanding how the meter has been changed to allow it to be secured in the two different meter sockets because the covers are different. They are doing the digitals around here also .. only to all service sizes. The utility employees either have a ring less meter or ringed meter on the truck.

The meter has not changed. It has always had the outer "ring" and fits into either a ring-type socket, or the ringless ones.

As stated elsewhere in this thread, the ringless covers allow one to remove the cover without removing the meter for testing, etc.

Aren't the ringless ones single? The ones with rings are married right?
