    On the fiddle ______________

    The return 'fake neutral' is 16mm same as the live conductors, the consumer unit is fed by a 16mm 3core SWA.

    On the fiddle ______________

    Yes maybe it does register usage so they can just toggle between 'free' and 'paid for' not to arise any suspicion, and/or if any one comes to check everything seems to operate correctly.

    On the fiddle ______________

    Diagram looks right to me, I'm not sure if the meter was 'registering usage' it merely sprang to life. The conclusion I came to is that the meter must need a neutral terminated 'to it' to operate and read correctly.

    On the fiddle ______________

    https://ibb.co/qRhctQk Came across this setup today, upon further investigation i noticed the distributors neutral terminal completly slackened off in the meter (looked intentional) is this to prevent any possible current from returning via the meter? With the 1g switch (just above DB) turned...

    --------Downlighter fault!!---------

    I drew the diagram out for this so I could understand it easier and yes its definitely likely as the neutrals on the fittings aren't hard fixed and are magically looped somewhere under the cover of the fitting, just trying to think of the best way to test this theory? Disconnect all fittings...

    --------Downlighter fault!!---------

    I will try to explain this as best as I can, Wired 18 downlights in two rows of 9, The downlights were wired in 3core and earth cable so two switch wires could be used to switch the downlights however the customer wished. It was opted for the lights to be switched in banks of two on alternating...

    Coding question

    I will try to explain this as best I can, Did and EICR this afternoon, multi story apartment block DB's in flats are effectively submains from switch room in basement, Fed with 3 core SWA, 2 cores supply peak side and the 3rd core supplies off peak side. Problem is, is that the neutral is shared...

    Open Ring

    Sorry my fault, not the code but actually what item on the inspection schedule.

    Open Ring

    When a open r1 conductor is observed on end to end measurements what is a suitable observation to note on the inspection schedule? Would Co- ordination between conductor and overload device be included because the CCC has now been affected. Thanks

    Ok so 60A semi enclosed fuse at 800A gives me a dis time of 0.2 Square root of (800² x 0.2) 95 3.7 So a 6mm ally earthing conductor should be acceptable?

    Those graphs make my eyes goes fuzzy ?

    Adiabatic

    Sorry it's a building with a block of flats the flats are fed from meters located in a communal hall with each flat fed from the bemco, I've never really understood why a shorter disconnection time requires a smaller earthing conductor, as It stands with a 5 second disconnection time min earth...
