Existing meter base amp rating.

[nizak]

Is there a way to determine what the maximum ampere rating of an existing meter socket would be if there’s no printed info inside?

Existing load center was a split bus panel so I really can’t go by an old main breaker size to help determine what it is amp wise.

Wire is #2 Cu.

Calculated load of the residence is 84 A.

I would like to install a 125A main breaker load center.

Changing out the existing service would be a large undertaking.

Meter base and riser are embedded in split shale stone and removing it would severely damage the stone work.

Also LB through and into the basement has been built over top of with a deck that would have to be cut open to access.

Thanks

You might be able to eyeball the size if you cannot open the cover and look for a label. Around here we typcially see the old round 60 amp, square 100 amp, and rectangular 200 amp meter enclosures. The 100's are small and square, the 200's are typcially taller to provide the proper wire bending space.

Can you post a couple pics of it?

Its rectangular but not the physical size I would know as a 200 amp overhead socket.

Thinking back, the old split bus panels seemed to be rated at 125A and most often on a “square” 100 amp socket.

And usually wired with #2 or #3 Cu.
