What size fuse??

welsh_bloke

Been having a bit of a sort out and found my old freeview recorder. It is however minus it's plug!
I want to give this to my boys to use at home in their bedroom.
I've put a plug on it which is fitted with a 3 amp fuse.
Is that the correct size fuse for the item??
Cheers in advance!

Figment

3 amp is correct.

Is there a label that shows the power consumption that you can post?

I'd assume 3A is ok from my own recorders tho

Edit - beaten to it...

I can never understand fuses, if you go out to buy a plug you can almost guarantee that it's going to be fitted with a 13amp fuse. But this is way to big for most things.

If it's still working and the fuse doesn't keep blowing then yes

A 3 Amp fuse will protect up to 750Watts in round numbers. A freeview box will be much less than this. but a 3 Amp fuze is the minimum size for UK plugs so it will be fine.

FYI:
Realistically speaking you only need larger size fuses when the device draws a lot of current. A quick rule of thumb is 4 amps per kilowatt (kW), Kettles and Electric fires can be up to 3 kW so need a 13 Amp fuse.

The funny bit is that things with hefty electric motors (vacuum cleaners, washing machines etc) although rated at much less than 3 kW do have a momentary high inrush current when they are first switched on and will pop a smaller fuse. These should be fitted with 13 amp fuses.

Thanks all for the replies. Thought 3 amp was the correct size but wanted to double check!

The label states:-
220-240V AC~50Hz. Max.20W

In which case your device will take around 100mA.

Watts = Volts x Amps

20= 220 x Amps

So; 20/220 = Amperage (0.09 amps)

A 3 amp fuse is OK. :-)
