When this was installed in 1937, they used 1 1/2" nips to connect from one box to another, back then they din't use bonding locknuts or bushings, so the entire system is all loose bonding, dependant on pipe and locknuts, i think we do a better job of bonding in todays installations.

Great photo. I like the old meters and switchgear.
As per chatroom discussion 9th of April I hope you get the mystery 7 Amps sorted out, but I think you have it already under control Les.

Les,
What are the white cylinders at the top of the pic?

Alan, you see an insulated pipe, probably a drain line, with the insulation interrupted by a hanger.

I was thinking a steam pipe.

I think that shows the difference between where Reno and I live.

New England vs the desert.

I really enjoy looking at pix of old installations such as this. Things have come a long ways, with modern inventions such as wire gutters and circuit breakers .

I have a panel in my collection, very much like the first four shown on that long wall. The panel is typically sealed by the POCO, and inside there is a single 30 amp main fuse, an EXO switch, and also a small knife switch inside the box - I presume to shunt the meter out of the circuit for testing or replacement. The customer's fuses (all two of them) are in a little "appendage" on the bottom of the panel with a little door that swings up.

It would be interesting to know what is in the main disconnect switch .
