Light sockets

Something that has puzzled me for years.


Bayonet cap and Edison screw light bulbs can be removed without tools thus exposing potentially live terminals and presenting a distinct shock hazard.  made worse by the fact that you often need to stand on a chair to remove the bulb.   There are millions of these installed yet the regs seem quite happy with the situation.

  • To be fair you can drive a 1920s car on the road here, and maybe changing pre-synchromesh gears is a bit fiddlier, but the operation of the basic 4 cylinders gas clutch and brakes and all that  are much the same. 

    I do not think there was a Mr Bayonet - the connector is based on the quick coupling on the end of the British Army Rifle used to attach a pointy thing so that when you had run out of bullets you still had a weapon for close combat. Bayonet connectors turn up in other disciplines too, like compressed air.


    So who writes the lampholder standards ?

    well

    UK lampholder standard   Committee CPL/34/2
    Screw lampholder standard  Committee CPL/34/2


    You may think that is expensive for 80 pages of which most is the same as the last edition...

    more on that committee


    I suspect you exceeded your remit with the PAT fails - normally parts meeting another accepted standard are considered out of scope of test.


    ( I just need a standard for a pair of upturned forks on a piece of floorboard that can be livened up by push button to cook sausages etc so I can make my scouts 'danger of electricity' demo fully PAT compliant.. ?  Pickled Gherkins go well too, you get a sort of internal thunderstorm with a bright orange tint that I assume is at least in part from the sodium D lines around 589nm from the salt in the pickling solution.)


    Regards Mike.
