    Lost neutral on PME consequences

    Interesting, my village has a transformer mounted on 2 poles, its very easy to get to as its on a public footpath, this seems to have a rod much like the ones at the bottom of the services poles, the dog keeps the resistance down by keeping it watered ? There is another very small...

    Lost neutral on PME consequences

    The black cable running out of the joint on the left of the image is the feed to the new suppy head, I am not sure what the black cable in the middle is, it looks like it runs under the joint, but I would have thought any cables would have to come out of the ends, I think when i looked...

    24v supply in boat

    So the DC negative can still be bonded to the hull, but the hull cannot be used as a return path like it is in a car

    Electricity supply to garage in block

    I mate of mine has a similar scenario, he wanted power in his garage which was part of a small block and 100m away from his house, The run would have had to go across his garden fence and 2 others. The others seemed happy enough with it at first but soon started to change their minds. In...

    Plug & Play hot tub installation

    This is a bit strong and it is not that clear cut there are so many factors to take into account, you can't just say every single outbuilding needs to be TT (what if that outbuilding is a granny annexe constructed in exactly the same way as the house ? , if PME is ok for the house why not the...

    Lost neutral on PME consequences

    So historically true TN-S with the old bitumen type cable was most common, then PME came along and now most of the UK is PME and alot new installations So what changed? , I guess the DNOs figured they could save some money in losing an extra conductor, As mentioned before in the thread...

    Supply a third fuse board for garden bar

    63ma do you mean 30ma I guess it depends on the installation method of the cable as to how much current can be drawn, The garage C/U is protected by a 32a mcb so the max current which can be drawn for an extended period of time is 32a regardless of what size cable you use to supply the bar...

    EV charging in a dwelling

    I wonder if a pedestal-type charger could be installed by the roadside, with some security to not allow others to use I guess, Of course they would have to own the land or have permission from the landowner not only for where the pedestal will be but also the buried cable root, EVs seem to...

    Lost neutral on PME consequences

    So my village has 5 PME electrodes at the bottom of the service poles. If I assume each one has a resistance of 30ohms (which is probably optimistic) the parallels resistance of all of them is 6.7ohm. If there was a PEN fault between the first pole with a rod and the transformer using the...

    Lost neutral on PME consequences

    I guess it shows they don't test them, as the joint is already filled with resin and they cant access it or disconnect the cable joining it to the PEN once the earth is filled back in, same for the pig tails i suspect
