My response among many, I am sure. The transformer is probably insulated
for about 5kV, with the centertap of the secondary connected to the case.
Ground one terminal, making sure the case isn't grounded, and now you've
got the core floating at 4 kV above ground. The 110V winding is probably
only insulated for 2kV. ZAP
