Ideal Twister Wire Connectors

[m4tty]

Hi,

Was at elex today and was given a few boxes of Ideal Twister Wire Connectors. The guy done a demo and put three 1.0mm cables into the connector and twisted. Then tried to pull the three cables out and they werent moving. You could move the cables anyway to pack them into a chocbox. The guy said 4 would easily fit in the small chocbox. They look really good and are mainly sold in America.

The design is the same as the old porcelin screwits.

Anyone used these before or use them?

Any comments?

Cheersut the kettle on

M4tty,

Would not use them mate sorry!

Seen to many loose screwits in my time.

Now Wago types on the other hand...

Can make it a sod to disconnect, and just like any twisted cable, they are prone to breaking.

m4tty,

You would not believe some of the nasty situations i've seen from the use these and other types of screwits.... Yanks love them, ...No-One else does!!

Those new Screwits have a spring in them right?? Cores can and do get caught up in those springs and you cant release them. Also, as others have stated twist a little more than is needed and single core type wires break in the screwit. This can cause high resistance and thus heating in the joint. There bad news all round, leave them for the Yanks!!! ...lol

They were banned for many types of connection means, in the UK over 30 years ago.. The last thing we want to see, is for there re-appearance.

Screwits just started to go out of fashion as I started in the trade, came across some on a job today.....housed in an Old Holborn baccy tin!!

Useless piece of information now.....Screwit was the name of the manufacturing company, the 2 types/sizes of 'Screwit' were known as Midgets and Normals...useless information ends! ut the kettle on

Cheers for the replies guys. They've been shelved. Not going to use them think I'll stick to lever wagos. Cheers

Good plan shelving them m4tty, I never liked scewits or wirenuts as our American friends called them. Good thread though, even just to make us aware that they are trying to bring them back in.

Cheers Steve

Haha!! Yes, i remember those old Baccy tins. ....A thousand and one uses they had too, including junction boxes. Seen them used as a sealed joint for a cable going out to the garden shed, filled with bitumen!! ...Now that's what you call ''IP68'' lol!!!

They have been listed in the CPC catalogue for a couple of years

Do you have some evidence of this? AFAIK they just went out of fashion when we started using solid core cable. If they bear a suitable BS number or CE mark they should be ok to use.

Then if you wish to use them, ....by all means you go ahead and use them no-one is saying that you can't!!! As i've said i've seen some real bad consequences due to the use of these dammed things, from both old and new spring types. They not only look bad in an installation, they were and are Bad!!!

The use of screw-its were classified as ''Bad practice'' long before the advent of single core cables, they were banned from use on most, if not all, half decent electrical contracts. Very similar situation with the use of conduits short inspection elbow, ...you won't see any of them on any half decent electrical contracts either..... Oh, and they have a BS type approval too!!!

Most household electrical fires were squarely blamed on screwit joints. The Yanks have been using single or solid core cables from the year dot, and to this day, they too have a disproportionate amount of household fires, that can be accountable to the use of wing-nut (screwit type connectors) joints!!!
