fuse rating question

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! Rich

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.

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.

--- 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.

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?
