Yeah, you got to love lifting those stingers off csp's, relying on that switch to be in working order! I normally check voltage at the secondary bushings to confer that it is working. Especially when it is a bank!
That stinger you lift and then release to grab the next can be suspect to backfeed.
We have all different terminologies from different areas and different systems. One bushing cans I think of those Y system cans. Can ground is bonded to the coils and neutral? and one primary bushing thats it? Just trying to get apicture in my head.
Ya most of our new transformers are single bushing, with the bushing on the top. 1 side of the primary winding is connected to the bushing & the other end is connected to the inside of the tank, at the same spot on the outside is a tab to connect your lead to the system neutral. On the secondary side there is a tank strap that is connected to X2 along with a separate case ground. Our 347/600s are the same except they only have 2 bushings.
