    testing for earth

    Hi everyone, I got this device to test sockets. https://www.amazon.co.uk/gp/product/B002QW3SL8/ I'm nearly sure that when I tested a double socket in the kitchen a few days ago, it said "no earth". I tested the same sockets this morning and now it's saying "correct". Is this possible? Could...

    Main protective earth bonding conductors

    We are now told no bonding is required if the Water enters via plastic insert, same with the Gas.. So why are we bonding the Lighting protection conductor to the Main earth terminal bringing an extraneous conductive inside the building,when we are actually trying to prevent this happening.

    UK Continuity Between Line and Earth

    Just tested the end to end resistance on a ring main at a socket outlet. Readings are spot on however when changing the crocodile clips I notice that I have around 600ohms of resistance between the Line and Earth conductors. The system is TT. What could be the cause of this?
