    Cheap AFDD implementation in flats.

    So, a flat 6 floors and above needs an AFDD on each socket circuit. At up to £150 each it is going to be an expensive undertaking if there are a number of socket circuits. But! ... A 40A AFDD can be fitted in the CU. It can supply the socket circuits which will have their own DIN rail mounted...

    Ring vs Radial : Identification.

    So three radials (or more?) can come off one OCPD 's terminal in the CU. That has been determined on this thread. My Question. A radial can be spurred off a radial, but can a radial be spurred off radial spur?

    The loonies are here in force again. Amusing indeed.

    RCBO energy consumption

    I mention all the devices in the house and inside the CU.

    RCBO energy consumption

    On a ring final circuit the cable current rating cannot be less than 2/3 (67%) of the MCB/RCBO rating. So, keeping this ratio, scaling up, a 40A RCBO/MCB, needs a cable current rating of 26.8A min, so 4mm cable is suitable as it is rated safely at 32A current capacity. So, installing a 4mm...

    RCBO energy consumption

    52p per ann. to run a neon light, which will be approaching a £1 now energy has risen. Have three and £3 per ann. With all the rest of the standing losses in the hosue and in the CU you can pay for a night out. Add all this up over a whole nation and maybe a fossil fuel power station feeds it.

    RCBO energy consumption

    Excellent vid. Even Big Clive commented in comments section. They pointed to another vid at Lewden testing AFDDs. AFDDs combine four fault protectors in one unit. The longevity of AFDDs maybe in question they have complex electric boards inside, unles you pay a fortune for the top quality makes...

    RCBO energy consumption

    You have poor comprehension for sure. No car crash. Get it sorted. At least try and get the prime points(s) as a starter.

    RCBO energy consumption

    You have poor comprehension. Read what I wrote again. It was clear enough.

    RCBO energy consumption

    I did conclude that. I also did post the same John Ward vid. ;) Great vid by John Ward. Big Clive tears a Hager down that had fried. Worth looking at.

    AFDD in 18th 2nd Amendment

    AFDD in 18th 2nd Amendment

    I do not have an end game. I was just doing an exercise of a low cost circuit for a flat using AFDDs - which three guys do not understand, saying it does not conform to the 18th and amendments. Sad reading from three so-called professionals. People might actually believe what you three write.

    AFDD in 18th 2nd Amendment

    Again.. The thread went onto an exercise of a bare minimum circuit satisfying a flat using AFDDs. It was me in post #135.

    It is you who developed an attitude, is making an issue of it. You run with it Mate. Still waiting. You know all the answers, tell us.
