WHAT SIZE FUSE SHOULD I FIT IN MY PLUG TOP FOR SAFETY AND RELIABILITY?

Learn how to correctly choose a fuse size for a domestic 13 amp plug. Not all appliances need the standard size fuse that comes pre-installed in a 3 pin plug.
Indeed, in many situations nowadays, this is a massively oversized fuse offering only the very worst of plug top protection.
So this video is a simple step by step guide that shows how anyone can easily and confidently determine the size of fuse for just about any domestic appliance using the information to be found on almost all appliances from kettles to bedside lamps, from toasters to computers and so much more.
This is invaluable help for householders, DIY enthusiasts and electricians alike.
We will show you how to read the appliance’s rating plate correctly and then how to quickly determine the size of fuse to use from a standard selection provided.

This was very helpful.

I bought some plugs (13A) for my 42w grow lights 🙈but it kept tripping my electric, after watching this video I changed the fuse to a 3A it seems to work.

As a daughter of a technician you would think I would know better 😂

Thank you for this, sorted my washing machine, followed your calculations, oh so simple, and the fuse in there was the wrong one, too low. All sorted, done and dusted in minutes.

Exactly what I needed to hear. Thank you!!

Wow! This is very informative, thanks for sharing it with us Dave. It worth it and the best tutorial on the topic for me.

Very interesting. I have an American made dehydrator. It came with a 10 amp fuse, however when I do your calculation (400w/240v = 1.7 amp) it only requires a 3 amp fuse. I'm l missing sonething....🤔. Thank you for the video it was a great help.

😊

Where dose the 10 amp fuse come in😉
3000 devided by 230 equels 13.04?

What happened if we use wrong fuse? For example for laptop plug top only need 3A but we use 13A. What function of the fuse? To protect what?tq

[tdhpst]

Is the purpose of the fuse to protect equipment, say a heater, and the cables connected to it? So if the calculated current is small, eg. 2A, a fuse of 3A would be recommended but you could use a 13A too? As long as the cable used has a current rating of 13A+ right?

So then if the current rating was 20A for arguments sake, you couldn't use a fuse of rating below 20A and the cable used for wiring it would have to have a rating of 20A+ right??

Sorry for the long question. Thanks for the video!🙏

So please explain why as standard my atx pc power supply rated at 450 watt came with an internal quick blow glass fuse rated at 6 amp 250 volt?

[colin]

Hi, thank you for the video however this has left me with a question.
I have recently opened my windows 10 pc switching power supply and found the protection fuse.
This was the fast acting glass tube type with a 250v 6.0 amp fitted, however the power supply was rated at 450 watts,
So by your video calculation formula this should have been a 3.0 amp fuse ref 450 watts divided by 250 volts =1.8 amps
Please can you explain why this 6 amp fuse is fitted as standard by the manufacturer of the power unit?

What happens if you have an 8 watt light at 240 volts, so you'd do 8w divided by 240v giving Would you use a 1 amp fuse?

[leemallard]

i have a outdoor floodlight to put up, with out plug, so when i fit the plug, to the 100w led light at 220/240 what fuse, as i did what you explained on here, and came u with 2.4, does this mean i use a 3 amp fuse ?

[docmarzia]

I have mixer and power amplifier with both of this equipment have same AC240V 300WATT..So what size of fuse do i fitt.. Is that 300 divide 240??

[yvuicor]

Hello what will happend if I use this fuse in 12 volt system , the fuse will let the current enter to the load ( 12v load ) ? Or the 12 volt current won’t be able to enter to load ?

[fukkingusernames]

I have a single plug 3m extension lead which isn't working. I removed a 5A fuse from the plug, would you not need a 13A fuse in it? Because a lead like this could be plugged into anything.

[muzeyicharles]

Wat fuse can I use if I have a kettle with 3 plates and each plate is rated 1.2kw...this gave me a current of more than 13amp.. the standard voltage for my country is 240v...help me out....on this

[sajad]

Why did you use 240 in your calculations, I mean why don't you use 220 or lowest operating voltage? If the device be electronics I guess it can has the highest watts in lowest operating voltage.

Hello, l am noob in electrical. Lately start learning some DIY for home appliances.
If a 3amp or 5 amp plug fuse blown is it Okay replace with 13 amp fuse? How to check good or bad fuse with a multi meter.

Thank you - nice one. Piece of advice to everyone: learn Ohms Law when studying physics in school - it'll be your friend, for
