All,
I truly am wondering if there are 2 different pieces of equipment, or if either term can be accurately used to describe what we commonly refer to as a "disconnect".
pauluk,
In the US an "Isolating Switch" refers to a switch that is not used to interrupt load current, but to provide a means to isolate the power from the load after it has been disconnected by other means.
(Sounds like a good definition for a safety switch to me?)
