Any voltage level in a coil system that has the potential to arc to the
body, and/or requires special consideration for arcing across a non-zero
distance, I consider  high voltage.

Thus, on the 60 Hz side, 120/240 VAC is considered low voltage by the above
definition. On the coil output side--unless the power input is very low, it
is to be avoided at all costs and may be considered super high voltage.

Though  60 Hz 120/240 VAC service is considered high voltage, it is always
assumed to be deadly, especially 240 VAC service.

Finally, these are definitions from a stand point of safety. This is not to
say that I do not appreciate the exchanges endeavoring to formulate a more
formal definition based on long held conventions.

Look--if you've got a pole transformer, its output should be considered high
voltage and given maximum respect. ...We all know this, however.....

Your absolutely right. It's currently at Terry's website here:

I was paraphrasing from section 7 "High Voltage Insulation".

Have fun!
