Operation overview
Your Socket & See tester has a special polarity test function.
It is a little known fact that a system can be reverse wired with Live (Phase) to
earth/neutral and earth/neutral to Live (Phase) The sockets will all work and
conventional loop testers will show and test that everything is correct despite
this very dangerous wiring condition.
Although extremely rare, this miswire condition can exist so if your test shows
this fault do not proceed - if in any doubt advise your customer to contact their
supply company immediately.
