Guys,
I am ASSUMING that these are like the dead front transformers we use in the East. Load break elbows on the high side, closable secondary side. NO LIVE PARTS are EVER exposed.

Trumpy, usually we don't use any circuit breakers at all on the high side, just oil encased fuses, and they are also not exposed, of course.

The only requirements are fire resistant clothing. Using gloves, sleeves, and a 6 - 10' shotgun stick.
