The repair shop regs, at least here in Scandinavia are clear. Each
bench must be supplied by an isolation transformer and have a leakage
current trip.

How can a "leakage current trip" function in conjunction with an
isolation transformer? Doesn't the presence of the isolation transfer
prevent the "leakage current trip" from ever operating, under what
conditions would it operate?

I am afraid I don't know John. I am not an electrician. But I do
know there is a trip above each of the five benches (I can provide
a pic if this is of use) and a huge 10KVA isolation transformer in
one corner. The workshop has a gov't safety inspection certificate.
