Numerous Lights from one switch

Hi All I was wondering if using the attached diagram would this be a good design for switching on numerous number of lights in one switch. I assume it is in some form of daisy chain. Its the one that I have rung?.Jimmy

  • AJJewsbury:
    The word is "effective" and not "efficient" as I am sure that you, Andy, appreciate. A judge would ask himself or herself, "what is the ordinary meaning of the word?"

    Indeed - but given the context it's written in, it seems it needs to be effective in conserving fuel and power - not just effective in being switch-on-and-off-able. M'lud.

    Yes that`s the kind of thing I`d buy into


  • I`d never thought of a 6 limit either by lamp or by point.

    Back in the days of filament lamps (Remember them?) We used to allow 100W per point or per lamp unless we were reasonably sure that another wattage most likely applied.

    I also used a (mental) limit of 2/3 absolute max of fuse/breaker rating per circuit as my own "good practice" and considered that the odd 150W lamp would be used if only as a temp (Temps have a habit of becomming semi-permanent)
  • Some years ago I was working on a certain Opera House in London. The consultants had asked for all the corridor, stairs and toilet lights to be operated by one switch at the final exit door for the staff. I can't remember how many circuits of lights this required but I remember that they were being fed from 29 different Distribution Boards.

    The final design used Normally Closed contactors which confused the electricians as the circuit had to be energised to switch the lights off but at least this was fail safe and also meant that there was no chance of a contactor buzzing during a performance.
