Makes more sense, no plug/socket will last forever with constant plugging/unplugging

120 vac is limited to 15 amps, and 20 amps with the different blade orientation.They are little screws so I doubt it. I just use the VFT method!
If 240V is bad I shudder to think how you lot cope with 120v. Give me 415v 3 phase any day
what is your 120 vac limited to ?

We only use 115v on construction site for hand tools. Using portable transformers.
Our grid power here is 1~ 230v 50Hz or 415v 50Hz ~3

Yes, I have read that here before.
So my question still stands, with the added legal verbage "On construction sites".
I think it's 16amps but dying out fast due to battery tools. Not many people bother with them any more.
Household supplies can go pretty high on 230v. Some electric showers are 40amp. House sockets are 13amp. Then you can get 16 and 32 amp sockets on 230v. Mine was a 32amp.
I say 230v but I think British electricity is still nearer 240v.

Common 240 vac outlets here are IIRC 30 and 50 amps.
I always wire 50 amp ones in my shop.
FWIW I have read that in the 1950's in Southern California, PG&E wired 3 phase into houses. Many are still set-up this way.
I have a couple of SNOW tapping machines, and they are 440vac 3 phase only, with a 1/2 hp motor and the other one is 1 hp...talk about low current draw.
My ABB plugs say made in Germany. Maybe the pins were ChinaABB are Swedish
But in all honesty it's just a bad connection. On stuff like that it's worth a periodic check.
I've got Clipsal one in my garage that has got double screws for the cable clamps, but they were not cheap. I've connected them with a ferrule or without, doesn't seem to make a difference as long as it's tight.
If you want to try some ferrules I've got stacks of bigger sizes, I'm unlikely to ever use them all, I can post you some if you want (Obviously you need the crimpers to make the joint)...
Thanks for the offer much appreciated!

In France it's common to have 3 phase to most houses.
In the UK you tend to get one street on one phase and then other streets on the other phases so if one goes down not everyone is hit.

That sounds too much like work, wrestling that anaconda in/out of the socket.
Do they have a cam handle that pulls it in and locks it ?
I did a re-design on a large 4 conductor special battery charging plug, and
it had a cam device to push it in and out of the socket.

32A and 16A 110v sockets are the standard sizes, as already mentioned fast becoming obsolete due to the performance and convenience of modern cordless tools.
They area available in everything from a small "portable" 1.2KVA transformer up to large three phase 15KVA site transformers depending on the amount of people/tools that will be using them.
The 110v tools do also have the advantage of typically being slightly more robust than the 240v ones, although the reason for their use on construction sites is safety as the transformers are centre tapped so only 55v to earth.
We also do use extra low voltage (<50v) for a lot of out door stuff, security systems, etc.
Otherwise it is 240v single phase in domestic premises typically in either 60, 80 or 100A supplies, and then three phase in commercial premises.
There are some oddball ones, e.g. 200v 400Hz - but that's very niche.
125A 240v single phase CEE sockets are available, but I don't think they are that common - they are usually three phase when you get to that sort of size IME.
With those big ones you best be sitting down when you get the quote too.

My forklift only gets charged about 6 times a year
What BS was trying to say was hard wire the charger into an isolator and not have a plug. Assuming the charger could stay in one place this would be the ideal solution.

You should keep it charged up and stick it on the charger now and again even if it doesn't need it.... Keeps the batteries healthy
Oh I do. I baby my forklift. Never let charge go below 30%. Had it for 8 years now. Never had to add water to the cells either. Only had 1000 hours when I bought it. Now on about 1200

We've had a, I think, 200A 3 phase connector. The cable was stupid, almost knocked my mate out when it flipped over due to a twist.
Above that we switched over to PowerLocks which were several hundred amps (think we had 500A/phase). Individual plugs about 2" diameter. You have to push the earth in and twist, that locks it in and unlocks neutral. Then you insert Neutral, then L1, L2 and L3 in sequence. To unplug you did the reverse to ensure the equipment was always safe.

63 amp and 125 amp in 4 or 5 pin. The 125 amp ones are a pig to plug in and out sometimes!
There's still loads out there, we install hundreds of 7 & 10kva 3 phase transformers on site every year, lots of lighting and "power drop" where a line of the 110v sockets are strung along corridors.
It's then 5 minutes later @pete and his guys come along and rip it all down again
