2 conductors in the same Wago connector hole

It always worked for him!

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.

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.

Additional punctuation recommended!

I thought it was money related, not common sense.
I am all for scientific QA testing, especially ones that mimic real life scenarios and beyond eg the fine examples of real world urban MPG figures given for vans/cars tested on a circular track in low humidity or in a laboratory!! I thought the review of building regs in the last number of years was watered down to reduce paperwork, freeing up public access to kitchen electrics or..... was it just politics?

No fuse for the fan! Xpelair's data sheet for the DX100T is less than helpful, since it only shows a wiring diagram for a DX100, but it does show a fuse after the isolator, although it doesn't give a rating for said fuse.
Hopefully, the instruction sheet in the box with the fan is a bit more useful.

Here's a copy - it will be a 3A fuse

Which is the ONLY way an isolator for a timer fan should be wired. Triple pole isolators are only suitable for use adjacent to in line fans in lofts, etc., in addition to the isolator in the bathroom or immediately outside of it.

I don't quite follow?

 

[DPG]

Not sure I do either.

 

[brianmoooore]

Because using a FCU before the fan/light circuit provides the 3A fuse required by the fan manufacturer's instructions. The TP isolator does not provide a fuse.
Also helps prevent idiots turning off the fan permanently, since no fan, then no light either.

Isn't the 3 pole isolator in the 3 core from the light to the fan for isolation for maintenance purposes, switching it off wont effect the light, or is that wrong? See where you are coming from now, better to fit an unswitched spur to avoid an idiot switching it OFF, crikey I'm confused now.

Edit: Last post should have said "switched FCU"

Then a FCU installed thus, might fall foul of building regs, for a windowless room?

You can get a fused TPN isolator (live fused), if you're determined to follow MI's.

No, your right Pete you only want to isolate the fan.

 

[telectrix]

if it's a Bath rugby fan, it needs to be isolated. .

I doubt prof stephen hawking pondered this before his death. So the forum will decide....
Is it permissable to mix and match different makes of push fit connectors
Ie wago and them other ones by ideal as shown below and put them in the same wago box or other similar mf enclosure..
Even if not against the regs...is it a mortal sin?

I heard it 3 years ago.

I like giving old threads a 'like'..........along with a 'deleted member' ?

 

[chris parrot]

I certainly would never do that. It doesn't take many brain cells to imagine that there is a high chance of a poor quality connection doing this, especially with solid core conductors as the dipstick in the video has done.

On a side note, anybody using wire strippers isn't a proper sparks

Agree with the first bit but I have used wire strippers for 50 years, quicker , easier and do not nick the internal insulation or the conductor so be silly not to use them.
