Special polarity test function
It is a little known fact that a system can be reverse wired with Line (Phase) to earth/
neutral and earth/neutral to Line (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 incorrect wiring 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.
