Are you really allowed to use those twist on joint cover things on the US?

Steve.

You mean the red things?  Yes, we call them wire nuts and they are allowed IN A BOX

What is used in Europe?

[Taylor Hall]

Most of what I saw in France were these:



With a good inch or so of bare wire sticking out either end. Shocked me good a couple times because I never saw one with some kind of cover/box on them. After grabbing one accidentally while doing a cable run in an adjacent cable tray I went and got a small mirror I could use to look around before rooting about in cramped ceiling spaces.

I'm afraid that entire mill is a violation of every safety code known to man.

They don't make 'em like the used to. Sometimes, that's a good thing.

I can't speak for Europe, I'm in England!

We use junction boxes:

Very true, but in the factory, it seemed the more we we idiot proofed things, the better people became at being idiots!

Don't have the link but if you like that press check out the "Chinese manpower punch press" on Youtube-very impressive indeed!

Wire nuts work very well-when used properly.  Obviously there are too many violations in that pic to even know where to start though I suspect the wire nuts are used to allow quick repairs when the wire wears out!

Sorry about that.  From over here it was hard to see where you were standing. (Grin)  I looked up the junction box and found this.

Seems like  a good way to do things.  In the US we use boxes made from either plastic or metal and the wires come in and are clamped.  Once inside it is OK to fasten them together with wire nuts.  The boxes must have a cover, or be closed with a device such as a switch and cover,or a light fixture.

Rules are similar but not the same for industry.  (The boxes have to be made from tougher stuff, but wire nuts are still used.  Many people chose not to use them inside machines that vibrate.

The four way box I posted a picture of is a bit old fashioned now.  It allows the live, neutral and earth to pass through and provides connection for a switch and ceiling mounted light fitting:



Now it is done with the terminals in the ceiling fitting itself:



Wired like this:

Most people in England don't consider themselves part of Europe, even though we are... And here on the Isle of Wight, we don't consider ourselves to be part of England!

I like the terminal blocks, very logical and impossible to over-stuff when used correctly.

That sure is expecting a lot
