    what is my swa core size

    Before you get too excited you are going to have to calculate R1 + R2 for your circuit and add it to Zs and see what you come up with. There is more to cable size than the nominal current capacity of the stuff.. john..

    Rural bi-phase power, rotary phase converter

    I built a rotary pahse converter once, and it worked very very well to be honest. I would be here all night writing out the details, BUT you need to know two things.. 1, you have capacitors "in circuit" as it were all the time, this is what generates the "third phase" if you like, and 2, you...

    Here is how i do it without messing about with charts or culculators or any of that nonsense.. Firstly, yes, i know that they brought in an amendment that supposedly allows for the volt drop under fault conditions but i could alter my method to allow for that if i wanted. Anyway, we know that...

    Is someone stealing my electricity?

    Why would the OP care a crap about price?? It is not them needing a supply and they are under no obligation to supply the others. They should just dissconnect all supplies apart from their own and let the others arrange their OWN supplies. Why would they care a crap what this costs?? john..

    Is someone stealing my electricity?

    Ok, You are paying for ALL electricity used in the entire building. YOUR flat, YOUR eletricity. If it were ME, i would simply disconnect the other two meters, your power will still be on, and let the others have to arange their own supply. Not for you to worry about. Imagine if say, my house...

    RIP Mam ............

    I think Charles will be wonderful. See, one thing i think that practically destroyed the monarchy, was this "one does not get involved in politics" nonsense. What are they there for then?? Somehow, i think Charles migt just be a little more "hands on" shall we say.. john..

    How are we all coping?

    Yes, but it is all ********.. Apparently the power companies have all been making RECORD profits.. Funny how EDF have only raised power prices a little bit in france, but hugely here.. It is all just profiteering and the only way to put a stop to it is to FORCE the government to do so. The only...

    RCBO advice

    Yes, it is correct what you say, AND, as you say., if you could show that what you did was an improvement [or even just as good], then yes, as you say, you would be fine.. I would not like to put it to the test though!! john..

    RCBO advice

    All very interesting stuff, a lot of it largely crap. In the foreword to the regulations [i cannot remember the wording] it says something about following them can be relied on to demonstrate compliance with the HSE laws.. In other words, never forget, that one day, you may be called upon to...

    Dual RCD

    How do you work that out?? If you took your car to a garage and they said you needed new brake pads, [but you did not like the price] they would not fit wooden ones just to keep you happy. They would just refuse to do the work. john..

    1976 v today

    All utter bollocks, total nonsense promoted by those that would seek to promote the climate change "industry" As for comparisons with 1976 [which i remember rather well] that is a joke.. We had one and a half hot days. There is a special name for that; SUMMER. Back in 1976 it went on for...
