The use of isolating transformer to feed workbench,if the bench has multiple outlets THIS IS FORBIDDEN.
All supplies of electricity must be earthed IEE regs.
An isolation transformer is to feed the equipment under test/repair, and not connected to any other device or socket.
Any floating supply can have dangerous voltages on the poles,due to a number or reasons,hence the requirement to earth one of the poles.
Therefore the max voltage to earth would not be greater than the supply.
If an isolating transformer is used in the proper manner, then it will increase safety when working on the appliance under repair.
Another reason is that the transformer will limit any fault current,and in my opinion,this is the most valid reason for the tranny.
