Default Are 3A plug fuses really necessary? Why not always 13A?

On an allied subject, Remember some time back an incident where a person
died due to a fuse not blowing when a mains cable was taken up by an old
style beater hover, mostly made of metal.


I really don't think the size of the fuse on the table lamp is the issue
here. It is hoover not being effectively earthed that is the immediate
problem. If it had been earthed it would not have reached a dangerous
voltage and either the 13A fuse or the flex to the table lamp would have
melted and broken the connection.


That may be so but the early and mainly metal models of Hoover only
had two round pin plugs with the plug body made of a rubber material

ISTR my mother getting a new Hoover circa 1962 and while the cleaner
was a considerably different to Grans 1930's one the rubber two pin
5amp plug was hardly any different in appearance. Had to use an
adapter to use a 13 amp socket.

A lot of early ones were used from a lamp fitting,
Hoover even supplied the bayonet connection with the rubber plug at
one time.

The early Hoovers would have been used on DC supplies as well, any one
know if any area had DC sockets with an earth?

Good point. But if the only fault current was that passing through the
victim then no fuse on the table lamp could have helped.
