Piano Electric Power Switch Shock Hazard
By David Evans

[ Ref. Nigel Perry in 110704 MMDigest --

Nigel's 'hot' motor casing problem could be solved by a 1:1 isolating
transformer.  The motor casing could then be earthed without it getting
hot, as the winding connections would then both be floating.

Regards,
David Evans
