I want to test switch mode PSU'S and want the frames to be safe to the touch.NO nasty shocks!
1) My question; should I only ground the primary input and NOT the secondary of the ISO TFR? I supply input power to the switch mode via the secondary without earth connected?.
2) Second question; When I use the isolation transformer to test ANY device such as a microwave, I plug the microwave into the secondary receptacle of the iso tfr ( not grounded) would that make it relatively safe to work on that device or any other machine such as a DVD player etc?
Do the connections on the ISO TFR look correct and fuse on the Input earth side?
