2 conductors in the same Wago connector hole

Daniel Howard · May 15, 2018

I've just watched a video on youtube about installing a bathroom extractor fan off of the light switch.

In it the guy says how much easier this is when you use Wago connector blocks rather than a ceiling rose (about 7 and a half minutes in). He's using Wago 3-way lever connector 222 blocks, but of course 3 of the blocks need 4 connections, so he's shoved 2 conductors into the same hole.

Is this safe / ok? I guess 5-way connectors wouldn't fit in the box, and (as far as I can tell) they don't sell 4-way connectors.

Any advice much appreciated.

Depend on what hole you are talking about.

what's a vlogger?
a vlwangooer?
a wangovler?
a wagovler?
a wago lover?
that's me!

and whatever hole Pete, one at a time is the way to go, mate!

HA HA it certainly did. RIP Bob Grant.

In my early experiences with Wagos, I did try the two conductors in one hole (no smutty remarks please), non twisted

and one or other conductor would withdraw prematurely

. I then became more experienced and found twisting two conductors together gave some satisfaction.

Finally, as I grew in experience I realised one could have more fun when using Wago XL boxes, and you could have multiple pleasures.

Heard some bad things about the quality of these connectors, with some failures.
Are they the older lever type 222 ? Apparently the copyright expired on the design so there are loads of copies now, of varying quality.

I'm using the new compact lever type 221 and they are brilliant.
I use this place as the cheapest I have found so far.

these are the 221 style.

Sorry chap, but I can't believe any spark would try and put 2 conductors into one wago hole. It is designed for one conductor and the amount of pressure exerted on the conductor will have gone through many tests so that it could be deemed safe. To put 2 conductors is just crazy and would completely null the validity of all testing wago has done.
I don't think your 'pull' test quite ranks with the £50,000 wago spent on their tests.
Trying to stay polite (through gritted teeth)!

Happyhippydad your comments are duly noted and also informative. In these times of covering ones back we can lose site of a little common sense. I certify/test my work and would not put others at risk. I do try things out.....just try it out and see...does it work, is it a secure connection or not? As for nulling Wago testing, I disagree. After using push fit connectors for over 7 years now you get to learn any limitations from using different brands/products you use. The problem now is because they are so quick to use users might overlook to check they are secure.

Now I think we need the ‘Dirty boy’ button if not just for most of @SWD s remarks!

All jokes aside, I have to agree with HHD and disagree with your good self. In my early use of Wagos, specifically lighting etc for bathroom refurbs, I did try a couple of occasions of putting two conductors into one lever clamp of a 222. It wasn't successful in my opinion. I progressed to twisting together of said conductors (typically cpc's), which I was fairly confident about.

However since the introduction of the Wago XL, there is no need to take any risks, minimal as they are. There is also the point if you having to 'double up' on connections, then a standard Wago box is too small for the amount of cables.

Try the Wago XL, you'll never look back

That is exactly why scientific processes exist, because there are limitations of learning by gaining experience over a period of time. Not every problem becomes clear in time, to use a really extreme example the building regs were watered down over long periods of people trying things in small steps, eventually we were faced with that terrible incident last year in the tower block. Basically they skipped the scientific testing process because common sense told them what they were doing was similar and it looked ok in the end.
Not saying to conductors in one hole will cause a fire like that, but it's little decisions that can build up.

Most I think all.

Not using these connections and watching the video if 1.0mm was used rather than 1.5mm it would have fitted better you could see that what do the manufacturers say regarding two in one hole.
