I find some sleeved pin plugs are not good at carrying a heavy current long term due to economies of metal in the sleeve section of the pins.
My portable welder that runs with a non blowing fuse (brass) in the plug will melt some such plugs in about 10 minutes where others are fine, but then it does draw up to 25A. Sockets of good quality stand this current in my experience.

If you're taking 25A from the mains then you really shouldn't be using a 13A plug. I'm sure you know that.

Well aware Jeffrey, but there are not many places that have 32A sockets available!
Its never been a problem, I just make sure that the kettle goes on for a brew either before or after but not during. We did have problems with some German made dishwashers that were a little over 13A on UK 240v mains, they used to age fail cheap 13A fuses and needed good sockets and plugs. The ones that were really bad were the kitchen fitters "special wiring" jobs, two or three 4 way extension leads daisy chained together behind the plinth with everything plugged in to them, fan oven, gas hob, dishwasher, disposer, washing machine, hot tap, etc. Normally with a 6mm bolt for a fuse in the first plug top. Horrible. My old engineer friend had some 13A sockets in his workshop with a phase on each pin........................ To get back on topic, reading the literature there seems to be multiple standards for charging sockets already, what happened to standardisation? Surely this is going to be a big problem to EV owners until one standard reigns supreme over all the others?

My 3kW KB fan heater heats up the twin 13A sockets I fitted around the museum. http://www.kbmuseum.org.uk/kb_appliances.htm
So no, modern sockets do not take happily to the full 13 A load. I kept the plug with the non shielded pins on it deliberately, but believe it is the sockets themselves which get hot. Mike

We love standards. Let's have plenty of them
It's possibly fair enough to have different standards for normal (up to 7kW) and fast charging where the current is much higher. Some EVs have more than 1 connector for precisely this reason. Some charging points have more than 1 connector too. Now that EVs are becoming mainstream the charging situation needs a lot of sorting. More EVs means more incentive to fit public charging points. In urban areas with terraced house without driveways there are schems to fit lampposts with charging points. Still at an early stage. All a bit chicken and egg. There are now EVs with plausible ranges in the mainstream market. Notably the Kia e-Niro which has been getting outstanding reviews. That car will meet the motoring needs of many people, to the point where they are in very short supply. I'm noticing a lot more EVs around London. Mainly Nissan leaf, Renault Zoe and BMW i3. And more Teslas for the rich. https://ev-database.uk/car/1125/Kia-e-Niro-64-kWh https://www.carbuyer.co.uk/reviews/kia/e-niro/ev/review

Use a bayonet plug into a light socked,. just as my mum did back in the old days with her wireless,.
For charging a car put a hairpin in the fuse box. ……..bet this gets deleted.

I think there is still a fair bit of metal inside those sleeves! After all, it is only 2.5mm² wires feeding the socket in the first place if it's a spur! More likely to be the fuse clips and the fuse itself plus the springy contacts that grip the pins inside the socket aren't particularly beefy. I wonder how they compare with the 16A sockets used on the continent?

Out of interest, I posted a link to this thread on the uk d-i-y newsgroup where some folk with serious knowledge of electrical work post - including my own electrician. Not everybody on there is an expert, of course, but you might find other points of view of interest.
If you don't have or use a newsreader, there are various way of viewing the group but this is probably the simplest: https://groups.google.com/forum/#!topic/...zOgp8XC1Rc |
