2 conductors in the same Wago connector hole

[Daniel Howard]

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.

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!

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.

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.

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.

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 first time to heard that different brands mix together

I heard it 3 years ago.
