Fuse rating

What fuse do i use in my hair dryer

[logman]

A 13 amp is recomended for my claiol, 1200 watt

[stanleyman]

A 10 or 13 amp should be fine for most makes.

Didn't know you used a hair dryer logman!

[logman]

Shhhh...Works on rabbits too

[stanleyman]

Rabbits? Around our way we use a shotgun.

HEY EVERYBODY, LOGMAN USES A HAIRDRYER.

[logman]

Thanks for letting the cat out of the bag, thats another fine mess you've got me into stanley!

Hows the squirrel relocation going ? that really had me falling about the place !

Use OHMs law V/I =R.

Or in basic terms the voltage divided by the amps equals the resistance.

ie 240 (Volts) divded by 3 (Amps) equals a resistance of 80 Ohms. So look on your hairdrier what the OHM rating is then divide 240 by this b=number it then will give you an Amp rating. Use the fuse which is nearest or just above this figure.

It's extremely unlikely to find the resistance marked on a hairdryer these days jlbharper. They are all marked by the wattage at a nominal 230 volts so the amperage is a lot easy to work out by dividing the wattage by 230 volts.

An 1800 watt appliance is 1800/230 = 7.82 amps. A 10 amp fuse would probably be ok here but a 13 amp will ensure that it does not run warm and shorten its life.
