You must mean "Americunt", but anyway, that's right - the Type G plug.
That means your wire are rated about the same as ours even though your
buddy insists that they are running much less amps. So, again, with your
help, your buddy looks like a complete and total dipshit. However, in his
defense I will add that your whole system is bullshit as one can't take
one appliance and plug it in anywhere in the house as you have different
sockets for different rooms.
No we don't.
Then explain this.
All plugs with the exception of some plug top power supply units are
fused. This is in addition to the fuses or circuit breakers in consumer
Prior to the introduction of the 13 amp plug the BS546 2 A, 5 A and 15 A
plugs were used. With this system the only fuses were in the consumer
unit. 15 A sockets were generally given a dedicated 15 A circuit. 5 A
sockets might be on a 15 A circuit with multiple sockets or on a
dedicated 5 A circuit. 2 A sockets were generally connected to the
lighting circuit which was fused at 5 A. Adaptors were available from 15
A down to 5 A and from 5 A down to 2 A so in practice it was quite
possible for an appliance with the smallest size of flex to be protected
only by a 15 A fuse.
When the practice of using 30 A ring circuits was introduced (to save
copper whilst also allowing more flexibility) it was considered unsafe
to allow appliance flexes to be connected to such a high rated circuit
with no further protection. Due to this the plug/socket combination had
to provide the fuse. It was decided to place the fuse in the plug and in
order to make sure people only used fused plugs to connect to the new
circuits a new plug type was required: the BS 1363 13 A plug.
Putting the fuse in the plug also allows a range of ratings to be fitted
providing superior protection for smaller flexes. This is especially
useful for long small flexes or for extension leads that are not rated
at the full 13A. Fuses for fittings to BS 1363 must conform to BS 1362.
This specification describes a sand-filled ceramic bodied fuse, 1" (25.4
mm) in length and 1/4" (6.35 mm) in diameter.
* 3 A fuses (colour-coded red) are intended mainly for small load
(750 W max.) appliances such as radios and desk lamps.
* 5 A fuses (black, but so are other less common ratings) are for
medium load (1250 W max.) appliances such as desktop computers and TV sets.
* 13 A fuses (colour-coded brown) are for heavy load (3250 W max.)
appliances such as irons and electrical heaters.
* Ratings of 1, 2, 7 and 10 amperes are available and are all
coloured black, but are rare (1 A is extremely rare).
The fuses are mechanically compatible, but inserting a fuse too weak for
the appliance will likely cause the fuse to blow prematurely while using
too strong a fuse will degrade safety as the fuse will blow less quickly
or in extreme cases not at all in the event of a fault. Having said
that, most other systems do not bother with using smaller fuses to
protect the smaller flex sizes and it doesn't seem to be a problem in
Rewirable BS 1363 plugs are always sold fitted with a fuse, usually 13
A. This fuse must be changed if fitting the plug to an appliance which
requires a fuse with a smaller rating. Plugs with smaller fuse sizes
already fitted are sold but are not as common. As a result, before
factory-fitted plugs became the norm it was common to have a lot of
spare 13 A fuses around that had been removed from newly purchased plugs.
