Meter socket alteration

I'm looking at a job that currently has a bank of horizontal meter sockets that are ganged together.

The only knockout location in any of them is on the bottom. No top openings.The original install was designed for all feeds to leave the sockets and run underground to their perspective load centers throughout the strip mall.

Is it allowable to punch the top of the socket and use a sealing washer on the compression connector?

Iam looking at feeding two new tenants in the mall.

There are 6 sockets , 4 in use and the two spares are in the middle of the group and coming off the bottom isn't an option.

Thanks
Both new feeds can be surface mounted to the building exterior .
 
Depends on the enclosure. I have used both kinds where you can knockout the top and the ones you can only use with a threaded hub screwed to the top

Does the interior components leave you room to do what you propose?

I'd use a myers hub, regardless of listing issues - rubber washers that come with RT fittings will deteriorate, some within only a year or two and they will leak worse than if you had used a set screw fitting.
 
I will need to get the utility provider to cut their seal so I can see what the line side arrangement is in the socket.

Since I will be "crossing" that in order to get to the load side lugs on the bottom of the socket I made need a specific location to enter. Possibly more towards the front than centered or to the back.

I would get the blessing of the POCO. I did what you propose once and the utility nixed it.

For changing from 100 to 125 amp breaker and conductors?

IMO this not even worthwhile making such a change from user perspective unless maybe it is some definite fixed load and you do need the extra little bit of capacity. For a dwelling or other typical light commercial service - if you truly need upgrading from 100 amps you probably just as well go for 200 amps.

I think maybe you are thinking of that other thread? POCO didn't like me putting a Myers on the top of the meter socket and bringing load side conductors out.
