MK certainly used to make them, but I'm not sure if they do anymore. The part number is 639 WHI but the only supplier listing I found was listed as discountinued https://www.rapidonline.com/mk-639whi-round-pin-mains-plug-2a-fused-white-23-0331.
Assuming you mean plugs, all of MKs fused BS546 plugs took BS646 fuses.
Don't clock points use standard BS646 fuses?
One could do that. To what extent it would be a 'bodge' to connect the large cable directly to the plug presumably depends upon how easily it can actually be done (regardless of what the manufacturer may say about the plug's 'cable capacity'). If it could be done fairly easily (and satisfactorily) I'm not sure in what sense it would be a 'bodge'.
Fair enough - as I said, I don't think I've ever seen a fused 2A plug. However, I wonder where the fuse goes, with those screws where they are, I presume it must have going lengthwise 'up the middle'?
Yes, sorry, I obviously meant plugs - and yes, you're probably right about the BS646 fuses.
I've certainly managed to get 2.5mm² flex into a BS1363 plug in my time, but it was all very tight, so I would suspect that 4mm² might be very difficult, if possible at all.
Certainly not easy and one has to be very choosey on model. RS did a Marbo lookalike, the original Marbo required a slight opening of the cable slot in the cover and longer clamp screws. Very early on I picked up some unbranded nylon plugs which required minor surgery to one of the internal guides.
I doubt that, without some surgery, it could be plugged into a standard BS1363 socket, but I imagine there would be probably be plenty of room for 4mm cable in one of these! ...
I've only ever seen fused BS546 plugs (of any rating) in catalogues and on supplier websites. I recall they were always bloody expensive.
That all sounds very reasonable.
There must be lots of cables and adapters out there that on the one hand have legtimate uses, but on the other hand are potentially dangerous if misused. Most test gear uses 4mm shrouded connectors, many test equipment vendors supply cables and/or adapters which will adapt from a 13a socket to 4mm connectors as a standard item. Many more cables with 4mm connectors on one end and all manner of connectors of the other must get custom-made as part of building test setups. Lots of equipment uses generic multi-pin connectors, if two different manufacturers happen to pick the same connector but use a different pinout then the possibilites for dangerous combinations are endless.
Quite so - that's what I find myself saying/asking about so many things that get discussed here and similar places.
the degree of risk obviously does depend upon that - but when something is manufactured and sold, there is usually no control over (and often no knowledge of) "the situations in which it may be used".
Which is why I'm conflicted too often, yes I have an adapter cable; 2A plug to blue 32A socket, 0.5 or 0.75mm² 3c flex about 3m long which I assembled for a specific job and used a number of times once per year. Do I have any form of widow maker? yes of course. Do I have big plugs on small cables? you bet, including a 63A plug on a C13 and a 128/3 male to 16/1 female etc but all kept strictly under my control.
So it does. However, although a similar arrangement might conceivable just about be possible in the one that plugwash linked to, it stilllooks to me as if it would be a bit of a struggle with those screws where they are ...
