Sorry Dave, but Phil is right on this one. The fact that it's an
isolating transformer doesn't matter, it's the fact that it's in an
"earthed" metal enclosure (or it should be) and both plug and socket are
wired incorrectly.

I'm talking about many years ago. There was plenty of gear around with
metal parts - even cases - and no earth.

If a case is properly earthed the worst case fault will simply blow a
fuse. Assuming the cabling feeding the device is heavy enough. And you
couldn't even guarantee that once.
