From what i have seen there is no obvious metal conduit, so it seems its either the ventilation system that is fed by the same ring and goes...

    Isolation of lighting circuits?

    Me again, with another question which I fear will become more common as Smart Home technology becomes more popular. Lighting isolation: is it a requirement to have a switch which breaks the live circuit close to the light? Background: I've got some smart bulbs which I can turn 'on' and 'off'...

    Kitchen Socket Circuits??

    Thoughts please... probably heard it all before ;-) At some point I will be having a new kitchen fitted and I am going to be carrying out all the electrical works and any advice on the modern wiring methods of today would be appreciated. I'm used to the old wiring methods, where it was about...

    3 gang, Two-way Light Switch has two circuits

    Ey up, Did a quote for re-wiring a kitchen. That was straightforward enough but the client wanted replacement dimmer switches fitting to an existing 3 gang, light switch.

    Lighting Circuits......

    Without going into calculations, at what length of the main run from the D.B. on a lighting circuit do you get a gut feeling that it needs to be upgraded from 1.5 to 2.5 cable more referring to singles than T & E. 6/10A type C mcb LED lighting low design current so more of a V.D max loop etc.

    How to calculate the tabulated current (It) for circuits with multiple Reference Methods (A and B)?

    I am trying to select a suitable conductor size from Fig 4D1A of the BS 7671 Book, and am encountering a problem because the circuit does not conform to one Reference Method. The circuit conductors leave the distribution board in wall mounted steel trunking, then run through some steel conduit...

    Multiple circuits in breaker approach

    Doing an eicr on a landlord board, in a small 1940s block of bedsits, found a type 2, 30amp socket ring breaker with 5 x 2.5mm cables in it. I assume that 2 of the wires came from an empty adjacent 30 amp heater ring breaker that had been damaged (screwdriver busbar metal board bang) and the 5th...
