    Just remember the plug only does one fault at a time. If it reports a no earth fault, check again and see if it's reporting live and neutral reversed, as I mine did this year.

    Hawkeye????.............. the post is a year old!

    But surely a polarity tester IS to check for live and neutral reversed?

    All I was trying to convey is that if the tester reports one fault, which is then fixed, don't assume everyting is OK. I plugged in to a mains supply in a French barn this year. The tester reported no earth. I found and fixed that. When the earth fault was fixed the tester then reported live and neutral reversed so I plugged my changeover lead in. My 3-light tester won't show a polarity reverse until there is a working earth.

    A year old? Yes but I didn't find and solve the problems until this year.

    II found exactly that problem.  don't assume that it is okay,  although many would not know how to check the eart and rectify it. This plug will not work correctly without a clean earth.

    Read up on how to check the earth and what to do if you havent one.
