Question about pole-mounted transformers

[rob8210]

Hey Charlie and Labor,

I didn’t pay any attention to the second picture. Now that I do , I see that gang switch you mentioned Charlie. I also noticed that bank feeds a 4 wire service. It also looks like those cans have 2 primary and 2 secondary bushings. I don’t know the primary voltage but in my little world that bank would be feeding a 347/600v wye service. Now that would explain why the one primary bushing from each can would be tied together and should be grounded, it’s hard to tell in the pictures. All our transformers come with a single primary bushing now.
