Perhaps not 1amp but 3amp is common. But heck were back to
Plowman believing that he can run his 3Kw(+) electric cooker off
such leads as commonly fitted to table lamps...

Assuming that the BS1363 plug is actually fitted with a fuse and
not a twist of wire, a lump of metal bar or the shank of a screw
or bolt... As I keep saying, and Plowman keeps refusing to
address, the sort of bodge (by a end-user who might not
understand the risks), that is not possible -or at least a dammed
sight more difficult to do- with radial circuits were the lead is
protected at the panel rather than plug.

Err, what frecking cheek, Plowman is the one who keeps quoting
the theory, living in that perfect world were idiots are banned.
As for "Diversity" that in it's self is a bodge, it actually
acknowledges that a ring can be overloaded and thus one has to
guess to circuit loading the real world might bring and then if
needs be increase the number of ring circuits.
:
: Final ring circuits are for domestic premises only. For
workshops or

radials. As you'd
Wrong, ring circuits are acceptable in offices and workshops but
the regs limit the total number of outlets on each ring.
: do for fixed heating in a domestic scenario.
:
Not just for heating, the 17th edition [1] has likely increased
the use of radials being used for freezers, fridges and other
circuits/loads were it is unwise to allow unmonitored
disconnections due to the RCD being tripped due to faults
elsewhere or even 'non faults'... But then, unlike Plowman, I
have always been in favour of supplying such appliances via
dedicated radials, ho-hum, could the worm be turning, could
people like Plowman be eating their own archived words come the
18th edition?!

wiring regs
