    Why a separate earth for caravans

    I am an apprentice and was just wondering the reason why you have to put a separate earth into a caravan? My friend has asked me to do a hobble and bring a supply to his caravan from his board. I do need to earth the caravan separately right?

    Is this a genuine earth rod?

    Is this earth electrode a genuine, made-for-the-job earth rod, or is it something improvised? With the 2 nuts clamping the earthing conductor, it's different to anything I've seen before, though I don't come across TT installations often. As you can see, it's very corroded, and returns a Ze of...

    monitoring of earth cable

    We are planning to run a earth cable for a distance of 500m. Is there a way to monitor the cable if it was to be stolen? We need a type of alarm or warning device to tell us if the cable is missing. Thanks

    Main earth after cut-out replacement

    Hi all, After months of waiting, the fused neutral cut-out at my parents house has been replaced but I am concerned about the main earth. I believe it to be a TN-S as the main earth is attached to the back of the main incoming cable. In December, I got the CU replaced and isolator fitted and...

    Adding an earth rod IN ADDITION to a TN system

    I have just watched one of John Ward's interesting videos - It all makes sense apart from one of the final points involving adding an earth rod to an existing TN system. Not making a TT, but using the rod in addition to the TN system. This part is at 20 minutes and 8 seconds if you want to...

    Earth cable in kitchen - purpose?

    Hi, I had the house re-wired in 2018. I have taken the kitchen out and have found a new earth cable was installed but is not connected to anything. What purpose would this have? Is it for earthing the plumbing? Thanks, Hadley

    Would it be ok to replace an earth nut on a ceiling light with a cable / cable and loop?

    I am replacing my ceiling rose with a metal 4 spot light bar, the cables are to short to be able to secure them unless I release the block from the light it’s self. I can then wire it with ease but can’t get the block back into the fixed earth nut. Would it be ok to replace this nut with a...

    Is it safe to wire separate plugs to two devices previously wired to the same plug?

    I have an old hifi system that has a record player stacked on top of an amplifier. Weirdly, both are wired to the same plug. I don't know whether they came like this or whether somebody did it post purchase for some reason (I inherited it from my grandma). I want to pass the record player on so...

    Bypass PIR Motion Sensor for Earth in Clean Manner

    I’ve got a basic PIR motion sensor that I’m wiring into my garage just before the ceiling light. I’ve fitted it all fine and it works, however the light fitting requires an earth but the sensor doesn’t have a space for it in its terminal blocks. This is no problem and I’ve just joined the...

    3rd Floor Flat Lost Main Earth

    Hi All 3rd floor flat has incoming supply via Conduit which was being used as the earth. Conduit at some stage has failed leaving the property with no suitable earth. Would it be necessary to run a new sub mains and renew the supply also or is it within the regulations to run a separate...

    Maybe use copper Earth tape?

    I'm installing a new supply to a ceremoniously dumped welfare cabin. I can't see any legitimate reason not to apply section 717, welfare units are specifically mentioned and the thing is a mobile/transportable unit. In turn this dictates that it shouldn't be connected to a TN earth as to my...

    What is this small voltage between spa water and natural earth ground?

    I've noticed a strange voltage reading between the water in my spa and natural earth ground. The reading varies between .35VAC and .7VAC. My wife noticed a small shock from the water after inserting her finger in the spa while standing outside the spa. I tested the GFCI and it is working...

    Did it really need an earth?

    I was away at the weekend & the electrician came round to fix something. While there he decided to condemn an outdoor electrical light as he said it didn't have an earth. My wife didn't know better so she agreed to pay him. It is a lamp post 8ft tall made entirely of aluminium with a single...

    extension leads - earth leakage

    Hi all, I can't understand why but I always get a small (minimum 0.06mA) earth leakage reading on extension leads (even without surge protection). Is this normal? If it is, please could someone explain how earth leakage occurs on a simple extension lead? Thanks

    Earth Bonding - LPG Pipe That Does Not Go Underground

    Hi, Our cooker is LPG, fitted on the inside of an outside wall if that makes sense. The gas pipe runs internally then through the wall to the regulator and changeover unit mounted outside, around 4' off the ground. The pipe doesn't go underground at any point. My understanding is that it...
