from switches and sockets. Often damaging wires. In two
cases
that I've seen, they shorted a hot wire to ground so their fix
was to go to the circuit box and swap neutral and ground.
Nice surprise when I had to fix the water heater.
I don't think UL has anything to say about both lines being
switched by a common switch. I think they only talk about
an independent switch on neutral as being a problem.
UL is only interested in safety of the operator and not
the repairman. As long as it doesn't make the chassis hot
or start a fire, you can get UL on something that blows
up the electronics of a unit every time you turn it on.
