Historical British Educational Film. Mummy and Daughter Change a Fuse Wire.

Zoomup
A delightful old film. How times have changed.

    Alasdair Anderson:

    My one complaint with the film is that rather than forming the copper strands into a hook shape, I was taught to make a complete ring and twist with the wire to stop it coming loose (wrap round a small screwdriver shaft and give the screwdriver one rotation) which is much more secure - but not needed with modern plugs.




    Very neatly done with those shepherd's crooks! I think that I have done it both ways.


     



    I think there was a convention regarding the direction of the "wrap"  - the first one (the source side of the fuse) was made in a clockwise direction, so tightening the screw tightened the loop - the other end was made anticlockwise - so tightening the screw didn't stretch the wire, reduce the cross sectional area and thus reduce the rating


    Slight miscommunication here!


    I was referring to the very neat wiring of a plug at 9:06 rather than the fuse. By both ways, I meant that some days I have made shepherd's crooks, and on other days little eyes. But I see what you mean about wrapping fuse-holder screws both ways in order to avoid pulling the wire.


    To be honest, I am not sure that Father taught me that, but we were certainly taught to put on a plug or change a fuse (wire) by primary school age.


    It saddens me that these life skills have become more or less redundant.
