Okaaaaay.
13A. You can have one single or double socket on a spur; anything else must be through a 13A fuse (or to be pedantic a 16A MCB but they aren't readily available in faceplate style so need an enclosure etc).One spur really isn't adequate for 3 heavy load appliances.

That's pushing your luck here.
A Type-B 32A CPD needs 5*In or 170A for instant trip, whereas a BS1362
13A needs around 7*In or 91A for "pretty quick trip". Quality & most likely age is a factor - a fuse dissipates about 8W at 13A. You'll be delighted to know dodgy BS1361 fuses exist: no sand, they don't 'arf go bang.An MK double socket is rated to 19.5A continuously. It is indeed worth running a new spur from wherever to at least another double socket.
There is a small chance the "32A ring" might actually be 32A radial in
4mm. For some houses it can be much simpler than forming a ring in 2.5mm, so do not be surprised. There is a length limit because 4mm CPC in just 1.5mm (lawd knows why, could easily have made it 2.5mm but there we go). Almost makes you want to use 6mm, but getting twin of that into a double socket in 35mm backbox just isn't going to be funny.If you want to use one-multiple 3-3.3kW appliances on an extension lead, use H07RNF in 1.5mm. That has 16A continuous rating, is pretty tough and the 1.5mm vs 1.25mm offers a bit of leeway re local heating. Some dryers have heater covers that get scalding hot on the back if the cable is nearby.
Moulded plugs on some appliances are just junk these days. I have a suspicion some makers are using different insulation (90oC rated) or assuming short duty cycle (kettle) to get away with ever thinner appliance leads. The result is whilst cable heating is obvious the plugs can run almost hot which doesn't help backbox wiring. My AEG runs about 3.2kW and after 2hrs the 1.25mm flex is like spaghetti, the plug roasting. No doubt the fuse tabs aren't great - put a proper plug on it and the temperature drop is very considerable. Putting two such plugs in an extension would probably get quite nasty - some cheap extensions have very thin busbar inside.
We should have done a miniature-body hybrid of BS4343 (round-pin) 16A radials by now for high current appliances, and likewise cookers which I can't help but think would benefit from a 32A plug-n-go. No doubt the AD BR P Stakeholder Crowd will buy a shedload of clipsal series 56 and create some statistics in order to mandate their usage.
It's on the WD-40 website. Others include:
# Squirrels pinching your nuts? A squirt of WD-40 on your bird table stand will help prevent them from pinching food left for feathered friends. # If your favourite 12" has a light scratch, a quick wipe with WD-40 will help prevent the record from skipping. # Caught with a stuck-fast zip? A squirt of WD-40 will help get you out of jam.
I really don't want to think about squirrels pinching my nuts, my favourite 12", and a stuck-fast zip at the same time though.

It shouldn't be, if the spur is 2.5mm. The radial should be wired in the same size conductor throughout.
No. :-)

That one was on a BBC Radio programme I caught last week:
I assumed that was a joke!
There are some possible horrible bodges to make it work, but in sensible land a new 2nd power feed is needed.
Re 2.5mm2 spurs, the cable's rated at 28A clipped direct, and note this is a continuous rating, exceeding this short term is normal practice seen on numerous 2.5mm2 rings.

WMD45 hasn't had the same success ;-)
So, a product thats been around since 1953 and is now a household name, selling $300 million worth a year to 148 countries - is simply down to marketing?
Fuck me I'd love to know the name of that ad agency. Nothing to do with that fact that it actually works then?
Actually many sparks do run 1G & 2G in 2.5mm off a 4mm 32A radial, the reason being the 13A fuse in each BS1363(A) plug protects the cable.
The problem is the kitchen fitter comes along and adds another 1G or
2G socket, thereby ruining things. One reason why 4mm 32A, length aside, is not a bad idea in a utility or kitchen as it is kitchen fitter proof.Yes... makes it way easier to plug in a *welder*... :-) ... then again where's the fun without cut-down nails for fuses. Ok, I admit you can't miniaturise BS4343 32A very much so the idea is a total non- starter.
there are better products with little market penetration
good marketing is a lot more than using an ad agency
NT
there are way bigger products and market sectors than wd40 that are little more than marketing
NT
There are better specialist products certainly - better lubricants, cleaners, penetrating oils etc - however part of the attraction of WD40 is that it does lots of jobs well enough. People pay for convenience, and a "one can does loads of things" product is very convenient.
think I'd sooner use oil plus paraffin, does a better job
NT
Hmm, length-wise or width-wise ?
As a unit of measurement, it'lll not catch on that quickly ;)
Paul.
and can I buy that in a little squirty tin almost anywhere?
Even Halfords sell penetrating oil that works better than WD40.
Except that's why radials are required to have the same conductor size throughout, so the entire circuit is capable of carrying the rated current.
Nononono, you wire in two x 13A input leads to the welder and run it off two different sockets :-)
Owain
Cosmetics and religion for two.
Owain
Of course, but you are missing my point. WD40 is not a single purpose penetrating oil, but it will have some effect if used as such. Its not a specialist product at all - its a jack of all trades. One tin does lots of jobs well enough for people to buy it.
