BS1362 fuses are used in professional dimmers imported from the UK.

** Hey - rice muncher.

Hello, wheat muncher!

I am in Sydney, Australia.
BS1362 fuses are used in professional dimmers imported from the UK.

How do you tell they were really BS1362 without any printing on the
fuse? So its look is unique among all fuses?

** Learn to fucking read - you stinking Chink moron.

" Funny, I have any number of fuses in my bins with "BS 1362" printed on
them. "

They look much like this - fuckwit.

How dangerous is it to replace a 500mA fast-brown fuse with a 500mA
slow-brown one?

could be as dangerous as using a nail instead,

Nice post a couple levels up.
Thanks!

Meters like the Flukes are "Category" rated - 1, 2, 3. When working on
high capacity services, like 1000A 480V, you really want a cat 1
meter. You won't wind up wearing it as in your previous post. The
problem is not just the meter. Arc in meter causes vaporized meter
leads that turns into an arc between busbars - very dangerous.

I learned about 'flashover' only very recently.
Once you know about it, it's obvious.

In addition to the nominal voltage you have the hazard of transients
that could start an arc which will then sustain at the nominal
voltage. In the US, OSHA may also take strong exception to using a
meter without the right cat rating.

One of the hazards in high capacity services is available fault
current, which can be 200,000A. Fuses have a rating for available
fault current. The fix is to use "current limiting" fuses. For high
currents they have a clearing time of under 1/4 cycle. You handle a
200,000A available location by the fuse clearing before the current
increases to anything near that value. The earlier Fluke fuse is
certainly current limiting. The fuse opens before the meter leads turn
to plasma.

So *that's* the '40,000 A' number in the 11A fuse ratings.
I always wondered about those stunningly huge numbers.

The fuse in the later link is a mere 250V - not likely a cat 1 meter.

I pointed to that fuse to show that Fluke were not
undercharging for replacement parts.
That fuse is in a 'hobby / light industrial' instrument.

But a glass 250V GMA fuse in a meter may exceed the fault current
rating for the fuse. One of the fuses in my Fluke is 0.44A and is
almost certainly current limiting.

That's the same package as the 11 A fuse I originally mentioned.

Ironically, I popped it measuring automotive electrical stuff.
(Note to self: Don't leave meters on the bench with the probes
connected to measure current!)

Lesson learned.

Ignore Phil. He's mentally ill, and off his medication most of the

I really mis-interpreted his sentence. Apology is necessary!

The physics books I read did NOT talk about this danger. So were all the
physics teachers that taught me. Maybe I fell asleep when they talked
about this. In short, the "art" of choosing the right multimeter for the
right job was not covered by the physics course material of my school time.

It's really lucky that I was never hurt so far when playg with hobby
circuits...

don't feel so bad, it used to be an accepted practice to use your index
finger and thumb as a go-no-go voltage test.. I know some one that has
one of the first NEC or what ever they called it back then, books, with
that statement in it.
