WebSep 4, 2024 · It disconnects the ground potential on the primary from the 0V on the secondary and lets the 0V float so you must touch both secondary wires to get shocked. If you just touch one secondary wire, the potential at that wire becomes equal to your potential and the potential difference on the other terminal floats higher or lower maintaining the …
