    Circuits earthed on metal box/conduit: Does it need a rewire?

    I'm getting an old fuse board upgraded in an office block. The electrician has just told me that most of the circuits don't have earth cables coming directly from the fuse box. I've taken a photo of one of the light switches. (attached to post) 1. It has the earth attached to the metal switch...

    TN-C-S supply, shocks from earthed sink, latest test from landlord 200Mohm resistance between E/N

    TN-C-S supply, shocks/tingles from earthed sink. Latest NICEIC test (2017) from landlord shows 200Mohm resistance between E and N As above, do I have a floating neutral, is this causing a leak from N, via bonding on sink to true earth (solid kitchen floor)?

    Is this earthed

    Not used a meter before so following videos that can't talk back isn't helping me. Trying to test basic stuff I put on v resistance and 1 to plug live other on the case of the fish light and get a reading same on negative but nothing on earth..... Did a test live plug to the driver's live wire...

    Shocks from new washing machine. (Un earthed)

    Hi. Did a call out just this morning as customer was getting shocks from Kitchen sink. On arrival I could see the sink was earthed and had good continuity back to the main bond. The client told me that it was when he was using the washing machine underneath that he had the shock when he...

    Advice needed about earthed boiler

    Good morning all, We need a little bit of advice; we are looking to buy a property, and during one of the visits, the owner told us that he earthed his boiler himself as it was not done. He claims to have studied electronics engineering and other related things, but my partner is a bit dubious...

    CU replacement with earthed conduit and singles

    Just carried out an EICR on a flat that was wired in the 70s - with singles run in earthed conduit to each point and the trunking providing the earth at each socket/light point. Ground floor flat, so needs RCD protection on sockets at least and seems due a CU change, but I have no experience...

    UK Metal bathroom cabinet with inbuilt shaver socket not earthed

    I'm a pretty competent DIYer and always try to follow the relevant IEE/IET regs. Recently I ordered an LED bathroom cabinet from Amazon to replace an existing broken LED cabinet (the mirror was broken). The new cabinet is made out of aluminium, has LED bulbs in the glass on the front and a...

    Backbox not earthed?

    Had a look behind a 5 gang switch in my kitchen and noticed all the earth wires go into a connection block with no connection to the (metal) backbox. Also no earth to the metal front plate (which I understand is considered best practice rather than a requirement). Should that connector block...

    Went to a job today and noticed a length of metal conduit going across a pathway. The metal conduit is not earthed.

    I just wondered what people’s thoughts were as to weather it should be earthed being an extraneous conductive part? It’s fixed to the concrete floor and if there was a break down in insulation there could be a potential difference. If you do bond it could it be introducing a risk? 1598092922...

    Why does a bathroom rad have to be earthed to its feed?

    I'm currently in my MIL's house and saw she has an earth connection bolted to the underneath fin of the radiator in the bathroom which goes to the copper feed pipe. Why does this need to be done? I'm probably being stupid but i can't figure out what it's actually doing since the rad is metal...

    UK Earthing a vintage brass lamp to the lamp base

    I have a couple of old metal/brass lamps to which adding an earthed lampholder would be tricky (either the entry for 3 wires is VERY small or the lamp holder is integral to the lamp and is original). All of these lamps have a screw within the base which appear to be for an earth wire - is this...

    Does this metal post need to be earthed or bonded or neither?

    I have 5 x 6m metal posts sticking out of the ground used for 200w floodlights to light up a manege. This is a domestic stables. The posts test as 35ohms to earth. The installation is TNCS and has 30mA RCD protection on all circuits. The floodlight will be earthed and in doing so the post will...

    Lighting circuits are not earthed

    hi all, yesterday I went to carry out an EICR on a 1 Bedroom Flat. The lighting circuits are not earthed,the installation is about 40 years old. The only thing I can do is C2 would you agree? It has RCD protection. It has some class 1 fittings.

    SWA outer armour not earthed at either end.

    A friend at work asked me to take a look at the electrics in his shed, RCD would occasionally trip out, turned out to be a very loose neutral going in to the RCD. One thing I did notice though was that the 10MM2 SWA entered through the back entry point of both the shed & house CU and neither...

    Not properly grounded/earthed

    Hi All I know next to nothing about electricity and wanted to ask for some advice. Apologies for any cross-posting. I moved into a rented house in Spain a few months ago. Turned out it wasn't grounded. Providing a ground turned out to be a little complicated as the property is build on top of...

    Hi I have a question i cant seem to get an answer too. If you have a portable generator and you plug for instance a fridge or any appliance directly into it, how is the neutral/earthing provided?? I know already that normally you can connect the neutral and earth from an existing...
