The RCD I mentioned as being pointless and offered no protection. I was referring to the secondary output, the floating supply to the workbench test socket.
The RCD would still protect the primary of the transformer and wiring, however its only earth leakage that is protected,as the only earthed object would be the transformer frame and core, this would normally be earthed any way, and as you would not come into contact with any of the primary wiring,to trip the RCD due to earth unbalance,I dont see any point in using this device.
You either use an RCD to feed your test socket,or feed from isolating transformer, not both.
I would prefer a transformer,which does give some current limiting,should a fault occur.
