Can anybody tell me if these are used anywhere else, such as in Arizona? I know of a couple of recent explosions when plugging in a meter locally.

Thanks,

This is a reminder to check the meter socket CAREFULLY. We had some designed for a corner grounded delta system that were installed on a regular 208/120 Y system.

Needless to say: when the power company swiched on the power it went BANG!

And anyone looking at it LATER could say- "Of course, one of the line side lugs is connected to the can"

But it was not noticed by a good electrician, a good inspector, or a good lineman. Everything was tight and secure-

So as the man says: "Be careful out there!"

The meter socket is often considered the simplest part of the installation, 3-4 wires in and 3-4 wires out- what could be easier?

The notation of which meter sockets are involved remindes of of two things: 1

Also, any info of some used anywhere in the Southwest.
