    Light fitting no earth terminal and metal

    Hi, the new lights I have are metal and the earth connection doesn't connect to anything. I noticed the light that was there before someone had connected an earth to one of the bolts of the metal frame using a fork crimp. What would you do?

While rectifying some faults in the house I came across to the light and measure Neutral to live: 240 volts (which is fine ofc) however when measuring earth to live I'm getting 150 volts. I have checked for any touched wires with my Fluke...

    Are these earth wires connected to neutral?

    I found a picture online of a standard UK connection in a block of flats. Where I have circled blue, would those earth clamps around the orange cable somehow cut into the neutral wire to connect within the orange sleeving? Or are they just clamped to the sleeve for some arbitrary reason?

    Main earth size on TN-S

    Hi guys. I was on EICR yesterday, where i found that the main earthing conductor is with very small csa- no more than 2.5cm2. Also they run the wire directly behind the CU, where it is twisted with 10mm2 and continues to the MET inside the board. Ze at the board is 0.28 ohms and seems to be ok...
