Thankyou Don,
This has been very informative. I will read the HV 7200/12470Y spec
to mean that you can connect the transformer across any two phases
for a 7200 delta system or connect from any one phase to ground for
a 12470Y system.

Hi Gerry R.
The bottom line is that that transformer can only take 7200
volts. Over volting it can cause arcing in the can and that can
cause acetyline gas to form in the can, very bad, tends to blow
the lid off next time there is an arc in the can.
