Can any one identify this please?

As per title does any one know the model etc of this, i think it's Wylex.

Yes it is a double pole switch with (I guess) a fuse under the white plate.

Probably called a switchfuse these days. Almost certainly Wylex. But they dont make then like that any more.
This is todays version

It looks like its fitted upside down..And I spy possible heat damage on the cable at top right. The colour of the inner sleeve should be brown, but the sleeve is discoloured so it now looks black. Sign of a bad connection just there.


CAREFUL. That is live. It is also ALL live when the switch is turned off!!!

Yes i noticed it was installed upside down

Whats the best way to fit a new one without getting a shock?

Isolate the supply, however hard that is, it's better than being dead.

If you need to ask that question, with respect, the only way for you is to have a competent electrician carry out the work.

I'm not sure about "they dont make then like that any more". Maybe it is not absolutely identical, but the inside of one of those 'todays version' KMF switchfuses you have illustrated is remarkably similar to the OP's photo ....

... and, for what it's worth, I'm far from convinced that the OP's is Wylex (although I'm not sure who makes these 'KMF' jobs).

Kind Regards, John

Fair enough. Is that from an Australian web site?

No, it's from my (UK) cellar - but I put it in 'Australian mode' so as to allow a direct comparison with the OP's photo (which also might have been taken in Australia!).

Thanks for the replies guys, i'll dig me fluke out and isolate the wires.

You can see more of the damage on this one here..

How? They're the tails from that 100A fuse aren't they?

You could argue, that amd3 covers switchfuses as well, the "consumer units and associated switchgear" in my eyes (my boss concurs) covers switchfuses.

We only fit metal ones now, it's a right PITA, the plastic KMFs take up SO MUCH less room

Could be..how do you know which side is the feed in?
The bell-end who fitted it did it like that because that's where the tails are. If the feed in is from the other side to normal, then the fuse holder will be live even with the switch in the off position.
Very careful work with the Fluke, with a special revision of safe isolation procedures beforehand!

I think many people probably would agree with you and your boss - but where does one stop, and how sensible is it? ....

... is there, for example, really much material difference between a 60A or 80A switch-fuse and an 50A shower or cooker isolator/switch (or do you perhaps think that they get caught by Amd3 as well?!)
