Consider this before posting: Does every new topic have to turn into a rant about your favourite bugbear? Whether it is capitalism, socialism, planned obsolescence, Microsoft, Apple, or the guy at the bus stop with the odd body odour?
Power Point and Leakage Tester - NB 240AV Australian plug version. Every workshop should have one. There are also smaller ones which like mac2geezer says are just a plug with some lights on the back.
I also run my workshop through an RCD - residual current device - in case any of the gear I am working on has faults. They measure the power throughput on the active line and compare it with the neutral. If there is any difference - meaning some power is going out to the workshop and not returning, for example, through you to ground - it shuts down the power in milliseconds. This can save your life. Newer houses and commercial premises may have one fitted at the switchboard.
