I suppose if you got them in a good mood you could convince everyone that the indoor transformer lid was a specially-placed "work platform" for the switches?

WebS -- Was the indoor transformer rated 220 to 110/220 for convenience outlets and maybe lighting? It looks sorta' single phase.

Yes. The indoor xfer was for 240/120 single phase general lighting and appliance loads.

It's kinda spooky working around that thing. It's oil filled. Quiet as a mouse. Weird!

Come to think of it, the bigun is quiet too.

Good Morning Dave:
Concerning the small transformer, where are its primary connections located? Also, where is the OCPD for it? Is it typical of transformers of this vintage to have secondary connections which appear to consist of short conductor "stubs" coming through porcelain bushings?

This is a fascinating thread you have going here. I enjoy a great many of the threads here at ECN, but particularly this one of late. [Linked Image]

Thanks for your comments!
The line side is the fused disc. on the bottom right. The other three are fused load side disc.

"short conductor "stubs" coming through porcelain bushings?"

Yes they are!
