Interesting and fascinating.
Back in the '70s, at Plessey Beeston, the Lab Benches were fed from individual Isolating Transformers. The Benches were fitted with 5A and 15A Sockets to stop people pinching anything useful. There were a number of Emergency 'Stop' Buttons on each Bench. I don't know where the Earth Pins were connected to or whether the Supply was really 120-0-120.
We just plugged everything in - Gear we were developing and Test Gear - as normal.
Never had any problems.
