This is the basic question I'm asking. Is it common and regular practice to
inform the owner of a voltage as high as 245? And to suggest that he have
factory personnel come and look at each machine and examine PS taps and such?
And if he had hired a licensed electrician would the electrician likely had
informed the owner of the voltage difference?

I have 245 volts in my garage. Everything works great.

245 volts is a perfectly normal voltage. It corresponds to 122.5 volts
AC from a regular outlet.

There is no causal relationship, as far as I can tell, between
perfectly normal voltage provided in your shop, and your CNC machine
frying after 3 more weeks.

I have not yet seen a more inane discussion thread.
