Paul,
I have seen round pin type plugs,
used in some really old places, that I
have rewired, but I have never bothered
to check the British Standard on them.
And I am quite sure that they would have
been BS type, as all of the fittings and
plugs were made of bakelite, a popular
material, in fittings imported from
England, around the 1920's-30's.
We also used to import TRS(Tough Rubber
Sheathed) cable from a factory, in
Manchester, we are now taking this stuff out in huge amounts, as it is starting
to break down, it has been known to burn
houses down, as it is still protected
by porcelain semi-enclosed fuses, which
normally do not blow, until it is too late.
But, with regard to the BS 1363, fused
plugs, this is a really good system,
especially nowadays, where appliances
depend on the Rupturing Capacity of the
protection at the switch board, what-ever
this may be, to protect an appliance,
which, normally is full of semi-conductors,
not good, fused plugs should be used more
widely!.
