Bigger fuses are more spectacular when they go. I had the cutout fuse for the distribution transformer that feeds my house blow out one evening. Sounded like a shotgun blast, and I was having to pick up shards of ceramic from off my lawn from one end to the other.
oh I see! meaning by using 5A fuse, or 13A fuse, does not mean I am actually pumping a 13A power into my sound system? Million thanks for finally solving my doubt and your greatest help! Hehehehe.
Well done on being so calm after that capacitor blew.
Very interesting video. It would plausible that these glass fuses could give way given the fault current and thin glass enclosure.
The ceramic fuses has a small bit of ceramic filings / sand inside the help dampen the fuse blow.
Was glad to see that rapitest socket tester go, there's no substitute for proper testing and verification.
Keep those videos coming JW :)

my electrical meter stopped working on the amps side. wont measure amps anymore. but everything else continues to work. tried ohming out the fuses I get nothing. yet everything but the amps work. even the milli amps still. work. think its a fuse?
Great video, and test equipment destroyed at the end. That is the fun part of testing and experimenting. Keep up the great work.
Hi John. I am replacing a fuse in a guitar amplifier. The schematic and the pcb are both marked T500mA. The fuse I have removed says T500E. Are these essentially the same? I can't find any info online regarding the T500E fuse.
Thanks.
Yes, the important parts are the rating (500mA) and T for time delay or slow blow.
Hi, I was wondering if you could help answer my question since google doesn't have any answers for me.
My sister bought a bonnet hair dryer that came with two small glass cartridge fuses. The instructions say nothing about what they're for or what to do with them. What purpose would those fuses have for a hair appliance?
all fuses have the same purpose - they blow and disconnect the power if the current draw rises above the rated value. the small glass type fuses go in a holder installed somewhere on the device itself rather than in the plug. thats usually located next to where the power cord enters and where the power switch is, possibly a round black thing with a slot for opening using a screwdriver or sometimes a horizontal slot thats part of the same moulding as a 3 pin IEC connector. there is a chance they are fitted internally and you would have to open the unit up to replace them but in that instance it would be unusual if the thing were supplied with spares as they wouldnt be considered a user-replaceable part.
I have a fuse that blew in my refrigerator, glass 15a 250v with that ribbon middle but I cannot find a replacement anywhere, there are however that amp and voltage in ceramic microwave fuses. Is there any differences you can see in replacing the glass fuse with a ceramic fuse? it is in a circuit board on the top of the fridge. Thanks!
+Sarah El That sound at the end of the video is my worst nightmare in this situation! :)
hi John, may I have your great guidance, PLEASE.. this is Singapore and all of our wall plug are 13A (ampere). OK I have a sound system the Creative T6 Series II. and it actually came with 2 type of socket cable for us to power up the speaker system. one is 5A and one is 13A cable power plug. my question is, if I use a 13A instead of 5A power socket cable, is that mean the power will be larger? and if I use a 5A does that mean the power into my sound system is weak?
A fuse is designed to disconnect the power if the current exceeds it's rating.
It will make no difference to the amount of power the device uses.
Hi. Can you tell me the diameter of the cooper wire inside of the ceramic for 13A ?
Don't have details for 13A or ceramic fuses but for a 15A rewireable it is 0.5mm diameter wire. 10A = 0.35mm, 20A = 0.6mm
John in a pinch need ceramic fuse but none readily available, can I use glass fuse temporarily Class 1 Div 2 panel
steve gila - NO. A fuse should only be replaced by a new fuse that has the same ratings and is the same type. Although you can replace a glass type with a ceramic type if the rest of the ratings are the same. You should NEVER replace a ceramic type with a glass type.
Mark 1024MAK It’s not that bad. If there are no shorts, there should be no problem. Also, did you watch the video?
@@GRBtutorialsthat's correct, you can replace ceramic fuse to glass, if you see the video, you can get conclusion that there are the same, just the casing ceramic fuse strong then the casing glass.
hope make sense
My T10AL250V is white but on internet its a glass fuse as it gone white when blown?
White are normally ceramic fuses. Glass ones go black when blown.
@@jwflame Okey.
Cheers for this, it was hard to find online what does a ceramic 13A blown looks like. Since I don't have a multimeter, I will just buy a new fuse and hope that, that is indeed the problem.
Couldn't you test the fuse in a piece of equipment that you know is working? You could also use a torch (flashlight) and piece of wire or aluminium foil with the fuse in the circuit.
Hello John! Can i use Ceramic Fuse 10 A for 3 A plug?
If this is a UK BS1363 plug then yes - the plug itself is rated to 13A and various fuses can be fitted in them.
Hello john
Are you testing the fuses via a transformer or off the the line. I assume if your using a step down to increase the your current above that from a 13amp socket. Your testing a lower voltage and so there is less - arching as would be the case a 230. Please show us your test set up on future vids it's always interesting.

Christian Fletcher Tests via a transformer.
Hi John, are the glass fuses BS1362 please? Thanks. Very interesting.
Edward Fenech No, they are IEC127, the main difference is their rated breaking capacity which is far less than the BS1362 ceramic ones. They are normally used inside equipment.
Thanks very much for that John. I really appreciate your help. Keep up the good work mate!! :)
Would you be interested in doing some tests on some fuses as used in older consumer units in Germany and Sweden? They may well be used elsewhere. It's the DIAZED fuse system. they have an interesting design with inserts for the fuse holder which stops higher rated fuses being used on circuits than intended. the fuses themselves also have an interesting spring mechanism inside the ceramic cartridge which causes a small coloured button to be ejected from the fuse body when it blows, thus indicating a blown fuse. If you're interested I could arrange to get some to you.
Thanks for the really interesting videos
Paul Hughes Yes, always good to see how other systems and countries do things. Address and other contact details at www.flameport.com
can you use a T3.15 ah fuse for a T4 ah fuse AMP
It will fit, but if the current is between 3.15A and 4A, the 3.15A fuse won't last very long.
@@jwflame thanks
can i replace a 8A fuse for 3A fuse
Yes - but if something requires 8 amps, a 3 amp fuse will fail immediately.
+10 because of the stewie griffin t-shirt
The second glass fuse spews out something though... :D
