    11kV Powerlines

    2 wires = 1 phase. 11kV between the wires, but 5.5kV each relative to earth. The 'neutral' is formed after the consumer's step down transformer by earthing one side of the 230V output to a rod or bare copper radials, or, in my case to the centre of the 230-0-230 volt output.

    Failed socket!

    It's most likely to be a combination of a faulty socket and a slightly out of spec. plug, especially if the plug has been trod on at some time and slightly bent. Can't say I've come across it with a fixed socket, But I've had trailing multi way extension leads where certain plugs won't work in a...

    Failed socket!

    Polarity of an AC supply?? I presume you mean which live is strapped to earth somewhere to make a neutral. Whereas it would be possible to design this into an appliance where it might matter, the chance of a vacuum cleaner incorporating such a device is vanishingly small. They're made for...

    SSE 3-Phase Upgrade Gone Wrong!

    Difference between a switch and an isolator.

    SSE 3-Phase Upgrade Gone Wrong!

    Not really an excuse, whichever is 'wrong'. It's not as if the neutral tail has a grey outer sheath.

    The big difference in the electric terminology and installation regulations and practice in each country!

    I've brought them back from Europe for about the last 30 years, but now, as a result of Covid restrictions and now an extremely aged dog, I've been unable to leave the country for the last three and a half years, and my stock has run out. I brought back three in 2019, and what I thought was the...

    The big difference in the electric terminology and installation regulations and practice in each country!

    I checked out every tape on offer at the recent Exeter Elex/Toolfair, and found just all metric one - a 5m Stanley, although another supplier sais they would be selling them in the UK 'soon'.

    The big difference in the electric terminology and installation regulations and practice in each country!

    One thing I don't understand is why it's still almost impossible to find a tape measure in the UK that doesn't have imperial measurements on it alongside the metric ones, some 50+ years after we 'went metric'. A tape measure that you can't use either way up dives me nuts.

    Whose bright idea is the red text? Not brilliant on an orange field.

    Is it safe to plug 2 extension leads into a double wall socket?

    It's a room where someone sleeps, so it's a bedroom. Minimum standards were set in the Parker Morris report in around 1963. Anything built after this should have more than one socket in a bedroom.

    Is it safe to plug 2 extension leads into a double wall socket?

    There's no further risk with plugging two extension leads into a double socket over that with just one, but the real issue of concern here is why is there only one socket in a bedroom? This suggests that the wiring may be extremely dated (from the '60s?) and lack such things as RCD protection, etc.

    What equation can be used here to find the value of the capacitor?

    Reading that question took me back about 50 years!

    External Consumer Unit

    If you're looking for quality, use Vector II from Hager. A strong, well designed enclosure, which I've fitted many dozens of, without any failures, apart from the one that was mounted on a wall that was demolished by a runaway truck.

    Fitting bolt in fitting

    Agreed, but we shouldn't have to. See second sentence of nicebutdim's post above.
