[Shop-talk] Wiring a UK appliance in the US?

FWIW, I found a manual on-line that specifies 50 Hz, and also the
ground-neutral-live configuration.

I'm probably worrying about nothing (I know very little about cooktops); but
my understanding is that an induction stove provides power at a frequency
just above the audible range (around 25 kHz).  Since I have seen other
equipment (in the distant past) that only allows a limited voltage between
ground and neutral; I wonder if it's possible this cooktop would not like
seeing, in effect, 120 vac between ground and neutral.

(In that long-ago case, the manufacturer also didn't specify that neutral
had to be bonded to ground; I found out the hard way from being on a
customer's site trying to explain why we were having a 200% failure rate.
The eventual answer from the manufacturer was that their power supply could
not tolerate more than 10 volts between ground and neutral.  After that, we
always supplied isolation transformers to make it so.)
