That's what you mean by "buck boost transformer"? I've not heard the term used other than for switched-mode supplies.As in post #2 !
Two nations divided by a common language!
Actually all my training was in in my place of birth. UK!Two nations divided by a common language!
One is most likely to relate a particular definition based on their particular work environment, custom of use and experience, for me, it was known as a common term in powering various industrial electrical/electronic devices .Where did we get the term “buck”? Is it a male rabbit or deer, or a dollar, or bucking the trend, or bucking like a mule? (though that seems more apt to describe a fly back converter)
I feel like this is bad advice. A neutral should never be bonded to ground except at the primary service panel that connects to the outside power service. If you're using an isolating transformer, then one side of the secondary should be tied to the neutral on the primary side (in order to allow GFCI/AFCI breakers to detect leakage current). If your service has a neutral conductor, and if you're using a buck/boost transformer, the series buck/boost add/subtract should be on the line side, leaving the neutral connected straight through from the line side to the load side. At no point in this arrangement should any neutral conductor or any transformer tap be connected to ground. If the transformer has a chassis ground connector, that is the only thing that should be connected to ground. (Except the ground pin of this arrangement's output socket; of course that should also be connected to the input ground conductor, just as a pass-through.)You will also need to re-reference the earth ground conductor to one side of the secondary to replicate the grounded neutral.
You can make either secondary terminal a neutral.
You will then have two conductors at this terminal, one a neutral conductor, the other the ground.
It is explained in NFPA79 and shown diagrammatically.I feel like this is bad advice. A neutral should never be bonded to ground except at the primary service panel that connects to the outside power service
