I have been given the base upon which a fairly modern kettle stood, with it s cable and 13A plug. It has a protruding round shrouded socket in the cen tre, which is to convey power up to its kettle. Tests with a meter show th at the base should work, if a working kettle with a compatible hole in its base were put on it.
If the socket is of a standard size, so that most centre-fed kettles of tha t size will work with it, I am minded to keep the fitting; otherwise, I wil l dispose of the base or find some other non-electrical use for it.
So: are the centre connections on such bases standardized (and, if known, w hat is the standard called? URL?)?
