Can isolation transformer improve mains outlet safty

摘要

I would like to connect a General Purpose (mains) Outlet for use at the bench in a workshop, as safely as possible. I have available a mains rated 240VAC-240VAC transformer with both the primary and secondary rated at 8A. This could presumably support mains loads up to about 2KW as an "isolation transformer". I also have a commercial Earth Leakage Detector RCD double outlet which "trips out" for loads greater than 10A or current imbalance/Earth leakage greater than 10mA.
