What is the difference between a 15A 125V and a 15A 32V fuse?

Microwave broke the other day. I was headed out to the pawn shop to buy
another. Money is tight. The I remembered to open it up to see if there was
a fuse. Yep, the fuse went. It was 15A 125V. Now, I suspect that it will
blow a replacement, but of course I want to check before I buy another oven.
I have several 15A 32V and several 15A No V listed. I also have 20A 32V, and
30A 32V.

Is there any way I can check it out without needlessly buying a new fuse? If
it does work, I will of course buy the proper fuse before putting her
together again. But can I test her using 32V 15A, 20A, or 30A?

The current ( 15 A in your case) is the maximum current the fuse will
normally carry before it opens up. You usually select that based on the
wire size or current the device the fuse is used in.

The voltage ( which should be 125 V in your case) is the maximum voltage the
fuse should be used at. If you put in the 32 V fuse , it is possiable that
the fuse could blow if the 15 amps is exceeded but instead of opening the
circuit, it will arc over and be about the same as if it never opened up.
Do not use any of the 32 V fuses. You can always put in a higher voltage
rated fues in. That is if you find a 250 volt fuse rated at 15 amps you can
us it at any voltage less than 250 volts. If you put in a 10 amp fuse , it
will probably blow and if you put in a 20 or 30 amp fuse, it may not blow or
if it does there may be major damage or a fire.

so you are saying what I suspected. That I need to spend the big bucks on a
fuse to see if it will work.

You should be able to get a fuse for pennies. If you know where to shop,
and how to look pathetic, somebody might even _give_ you one. ;-)

Good Luck!

32V fuses can't stop 110V, and may explode when pushed to try.

a new fuse will be less expensive than replacing/refilling your fire
extinguisher.

maybe in the good old days, but this here is corporate america. Death to the
local shop, who's owner you knew by name. I had to buy a pack of 3 for 4 $
and have not tried it yet.

Jasen ment that you may have to use the extinguisher to put out the fire the
wrong fuse may cause.

Also it may not need it but every so many years the extinguisher should be
checked and recharged. Not sure what the law or regulations are on this,
but do know that where I work they are inspected every month ( have to do
that myself on some of them) and every so often they are taken out and
replaced with fresh recharged units.

Check what's downstream from the fuse. More than likely a rectifier
in the power supply. If you find a bad one, replace it and try
again.


** BAD ADVICE !!

Microwave ovens are killers.

NEVER suggest that a novice meddle with one.

How do you think that novices get to be experts?

By listening to your whining advice about what they should and
shouldn't do?

I don't think so, ya goddam pussy.

Just think, would us humans have actually walked on our moon if
you'd have been in charge of the mission?

No. Probably because Mum would have told you that it was _much_ too
dangerous and _no one_ should try it, and you never really got to
cut the cord.

If the fuse is gone, then to find out whether it's the fuse's fault
or not, _passively_ probe what's downstream from the fuse. If you
find something that's obviously bad, replace it, fit a new fuse and
fire it up. If it blows the fuse again, then there's more to it
than a novice can be expected to contend with and the effort should
be relegated to more competent hands. Or, as seems to be the trend
lately, throw it away and get a new one.

In any case, bugger you, you ignorant piece of shit.

In your case, it seems, by listening to Mum and taking no risks
whatever, which certainly doesn't qualify you as an expert on
anything but sucking tit.

Yawnnnn...

Got some evidence?

If not, you need to shut up unless you're prepared to go technical.

Pretty scary, huh?

Since you don't know what you're talking about, in the first place,
your advice to anyone who asks for technical help is, always,
"Forget it, it's too dangerous".

Is seems to me that that's the battle cry of the legion of cowards,
of which you seem to be a founding member.

If I subscribed to your prattle, I would be.

However, since your rhetoric has proven its underlying logic to be
fault-ridden and your stance to be less than that of, let's say, a
dog bitch looking for a meal, it's not likely that you'll be taken
seriously.

Cowboy.

Actually, no.

I just thought I'd interject something you'd be familiar with in
order to keep the thread going.

How clever of you to be able to edit a dotsig...

Just think, if you can somehow pull it off, all of everyone else's
pithy sayings will be attributed to you, even if you can't fathom
their meanings.

ok, so now my microwave works, as I already posted.

I have been using it with the cover off. I just noticed 4 1/4 holes on the
top of the heating cavity. They are not arraigned symmetrically. This was
made overseas, but they are between 6 and 7 mm in size. So, when I cook
something, I am pushing microwaves into my atmosphere. How far can they
travel? And can I out run them?
