True, but then the final protection would trip...

You weren't around in the days of those radial circuits? It was
common to

I was actualy...

see both 5 and 15 amp plugs on the same circuit.


But that is not what you originally implied, someone trying to run a 3kw
heater off a 5amp supply.

No - I said using a 5 amp plug. Didn't say anything about the supply,
which were usually a 15 amp radial.

What is the difference between someone running
a 5amp load off a 15amp radial circuit and someone leaving a 13amp fuse
in a BS 1363 type plug, or worse still, using that bolt to bridge out
were the fuse goes and thus protecting something at 30amp rather than
the correct 5amp ?...

The fuse in the plug top is to protect the appliance - not the circuit. If
you overload the appliance - or in this case extension lead - it will be
obvious by the smoke. Overloading a circuit with concealed cables is a
different matter
