The thing is, most equipment supplied with 'kettle leads' have a 13A fuse in the lead. It's the same for computer equipment. I've noticed recent purchases (Chinese/Taiwan manufacture) have a 10 amp fuse in the plug. |

 They are widely available (at a lot less than £90). |

I don't remember coming across that value - thanks.

My understanding is: A true C13/C14 cable is only rated for 10 amps and I'm sure the cables I got with most of my hifi had 10 amp fuses in them. On the other hand a real 'kettle plug' - i.e. used for an actual kettle - is slightly different and rated for 13 amp |

![]()  Just opened a brand new Marantz SA-11S3 and as expected a small fuse as shown with BS approval. I think this disproves that "all" new equipment is shipped with 13A fuses and that it would be reckless to change it to a 13A one ? Dave |

The mains plug fuses are ALL 13 amp Maybe this doesn't mean what I thought ?? |

It's possible that you may have misinterpreted it (or I have, it wouldn't be the first time) because I took it to mean that all of those £90.00 mains fuses were rated at 13A, thus making them unsuitable for most hi-fi applications according to the method I've been taught to work out suggested fuse ratings, which is set out here along with some example appliances. |

Yes, my thoughts "and" that people thought the fuse was to protect the cable and 13A was OK and now standard ? But Martin also said in a PM that "most" IEC leads were now 13A.
I just had to wait for a brand new box not made in China to check, and it was 5A.
I think there has been some generalisation and sheer bad practice ?

What is more they use non-standard wires. Of course you can change the fuse but RA for example puts a sticker on the plug stating opening it invalidates the warranty (unless they changed that more recently) LOL. |

Some clarification is required. I had a quick look at a sample of power cables provided with equipment in two large boxes at work. Most of them had 13A fuses, some had 5A and one had a 3A fuse. We have none with a 10A fuse. So my 'most' being 13A was statistically correct.
Secondly, the fuse is there to protect the cable. Most specialist cables like the MCRU ones are high current and easily capable of sinking 13A, and therefore blowing the fuse before melting. So a 13A fuse is entirely appropriate. Remember, the fuse is not protecting the equipment. It should have its own internal provision.

The SR black fuses which are what started this latest round of shenanigans are sold in 3 different formats.
One is 13A and fits a UK plug top. That is the only rating they supply in this fuse type.
Its 25.4mm long (1 inch) and 6.35mm diameter (1/4") or thereabouts and only fits a UK plug top.
The other fuses SR make in the blacks are 20mm long for inside equipment and 32mm long usually for inside USA equipment.
The above fuses are sold in slow blow and fast blow in many different ratings (500 Ma, 1 amp, 2 amp, 3.15 amp etc etc etc)

They're meant to fail to protect cables and equipment. Do they have any certification showing that they meet the criteria that they're claimed to meet? Do they have any regulation compliance markings? The Bussmanns pictured earlier in the thread have testing certification. |

This thread is about whether audiophile fuses work in terms of sound quality. While I agree that safety should not be compromised, I don't want it to be hijacked into a long and tortuous debate about the safety of fuses and equipment. I'll allow David to answer the question asked and then you can make up your own minds about whether you want to go down this route or not.

Any chance of an answer to this one from 16 Jan 2017 at 21:16 while we're at it? It's on page 5 of this thread Could you explain what you mean by those comments as I don't get it at all ... Martin, are all of your posh fuses inaccessible or could you check yours for kite marks etc. and lay this one to rest for us? |
