[stiffbuy1]

hi, i have a experience filteration mains lead, does anyone know the correct fuse to put in the mains plug as i bought it second hand and there was no fuse inside the plug , thank you for any information

Any fuse as long as it's the same rating as the old one.

In spite of Russ Andrews' suggestions a fuse is simply a piece of wire inside a sand filled tube. They all sound the same

13 amp is the most common in the U.K. but that's enough for a kettle or electric fire. Few Hi-Fi items even exceed 3 or 5 amps, except powerful amps, or those that surge on switch on.

If you are feeding a CD player or turntable, for example, then 3 amps is plenty.

RA fit 13 amp fuses to all their leads (I know I just brought another one) and I have used them on many different audio/video components with no problems.

Yes indeed, and I myself always use the lowest value fuse for the job but with these 'speciallist' mains leads normal logic doesn't always apply does it? As I said, the original lead was fitted with a 13A fuse. When they use especially thick cable (In the case of RA Kimber weave, 3x normal twisted together!) - they deliberately fit 13A fuses when lower would usually suffice, (don't shoot me, I'm only the messenger but the theory I think they put forward is that a lower fuse somehow negates the (already questionable) benefits of the thicker than necessary cable - Normal logic tells us of course that under non fault conditions, a lower rated fuse can only be a disadvantage to sound quality if it blows!)

So a 13A was probably originally fitted (for a 'reason') but 3A or 5A is all you need. As a poster recently pointed out though, with these detachable leads, the fuse is there to protect the lead not the connected device, which usually has its own protection.

...by the manufacturer according to the spec. of one listed on e-bay.

That's not to say that lower fuse ratings cannot be used (see the following posts)

Me too! I only wanted to highlight the rating issue for any other readers as so few folks seem to understand fuses these days. I must try a lower rated fuse to see if my wires sound "strangled"!

I'm sure there are benefits to system you use in the UK. I quite like the on/off switches on sockets. But faffing about with fuses in plugs is not convenient at all. All our electrical system have a 16 amp limit, so no need for fused plugs.

I believe the fuse in the plug is about protecting the mains cable itself, as the equipment to which it's attached should have its own fuse protection.
