come across it?
David.
I used to see it a couple or three times a year back when I repaired
group gear, often on HT fuses in valve amplifiers, and back when 20mm
fuses started to become common in equipment, but not common in toolboxes.

I think David was specifically talking about the BS1362 fuses found in
BS1363 plugs. The special (and varied) fuses in the HT amp.s and similar
are less likely to match anything to hand (i. e. another appliance's
plug).

Incidentally, I was at a presentation about Barbados the other day, and
was told that it's not possible to hire a car in Barbados due to the
previous amount of traffic accidents involving hire cars. They drive on
the left, and the majority of tourists are American and can't get used
to driving on that side. I myself prefer to drive down the middle
You remind me of a comment made by Raymond Baxter on Top Gear, back when
it was a motoring programme: he described some car as being "for the
middle-of-the-road driver", without realising what he'd said. (No, it
wasn't a Chieftain tank.)

The great advantage of radial circuits is that idiots find it a
little more difficult to bridge out the breaker in the panel,
unlike the silly fuse fitted in BS1363 plugs (which for some
silly reason is the same shape and diameter as many screws, bolts
and any other round bar) -
Well the BS1362 fuse certainly isn't the same shape as any screw, since
screws taper to a point, nor is it the shape of any bolt, unless you cut
the head off the bolt. As for round bar, well it would have to be the same
diameter and length, how many people have bits of round bar just exactly
the right size hanging around the house? not many.
For the last 20 years I have PAT tested every mains electrical item
submitted to a charity auction that is held twice a year in the village
where I live. In that time I met a fair few horrors: flexes so damaged
that the bare live wire shows through, a standard lamp (with a brass
fitting) wired up with two-core bell-wire, flexes extended using a bit of
choc-block wrapped in insulating tape, broken plugs, mis-wired plugs,
plugs with the cord-grip either missing or incorrectly used etc. But I've
only ever had one example of a plug with anything other than a BS1362 fuse
in it, and that had a few turns of 5A fuse-wire wrapped round the prongs
of the fuse-holder. So I don't buy this idea that people are putting
screws, bolts or bits of metal rod into plugs in any significant numbers
at all. Its *so* much easier to nick a fuse from another appliance than to
start looking for bits of metal that will fit!
How about 13A plug fuses for low wattage appliances such as radios and
lamps? Or wouldn't you regard that as a fault? (I wouldn't, as I regard the
purpose of a plug fuse to blow in the event of a dead short in the flex.)

As indeed it is. If the device (like a radio) needs fuse protection within
itself, it should have its own fuse. Exactly as it would have when fed
from an unfused plug.
I suspect if starting with a clean sheet now far more sophisticated
circuit breakers etc are affordable, things might be different.

Its enough to get the item a "fail", though my solution is to change the
fuse, not withdraw the item from sale as I do with the real horrors. The
longer that time passes since the law that required new items to have
factory-fitted plugs the fewer examples of this I see.

Can't be arsed to read the regs of a forgien country, we have enough
of our own. You are over there and presumably know them so how many
breakers would be required for 38 double sockets in the US?

Indeed I was. My comments were in the context of Jerry's assertion that
screws, bolts, metal rod etc. are commonly found instead of fuses in BS1361
plugs. As you say equipment fuses are far more varied in terms of size,
rating and rupture characteristic. They also tend to be a lot more expensive
than the readily available BS1362 fuse.
BTW did anyone here ever come across the alternative design for a UK fused
plug? I only met one once, it had round pins and looked fairly similar to
the old 15A plug, but the live pin *was* the fuse. The fuse had a threaded
stud on one end and simply screwed into the face of the plug to form the
live pin. I guess it was a different designer's take on the same design
brief that lead to the BS1361 plug. At least if we had gone with that
design it would have been much harder to bypass the fuse!
David.

Because it adds an extra mechanical joint to the that is not
