Wiska boxes with wagos

AFAIK the CCC of Wagos depends upon the JB. So Connexbox Wagoboxes used properly are good for 32 A. Other combinations are not necessarily certified as such.

I will ignore for now the question of mixing manufacturers, and how this affects type approval, as I think it is similar to the arrant nonsense that suggests a 16A MCB on a DIN rail knows who made the rail and box, and changes its behaviour, but does not apparently care about the number of other MCBs sweating away  beside it or the size of wire used or how well it is done up.

The question is ‘is it bad practice to let connector blocks (of any kind)  flap about on the wire ends in a box.?’

Maybe, if this is a place with a lot of vibration or sudden acceleration, where the flapping about matters because a wire may get fatigue failure or shake out. If however it is not a fun-fair ride or something, then the other big question is do the cables get pulled?. We'd hope that any flexes would come via a compression gland that held it tight, and any rigid wiring was held by clips or cleats. 

Apart from the spaghetti problem of  lots of tail end not fitting in the box, and perhaps poor airflow if the box is too full, I see no real issues, after all a similar approach seems to work for telecoms. 

It is however a bit ugly.

I have never encountered a problem in permanent buildings with choc blocks just suspended in mid air in an enclosure. 

1. The wires tend to be short.
2. The terminal is self supporting.
3. The choc blocks can have two screws per connection with the copper being passed under the two screws.
4. In machines or vehicles where vibration may be a problem, flexible wires may be best with adequate support.
5. Wagos have spring loaded terminals to keep the conductors gripped relatively firmly.
6. If dressing the wires is a problem, I use a bigger box.

Almost relevant, but fun pictures though.

Baldyhugh: 
My question was do terminations whether traditional strip connections or wagos require securing in an enclosure generally

May be my earlier response was unclear. It is not so much a matter of keeping the connectors held firmly as keeping the cables lying in an orderly fashion.

IIRC, the Wago literature explains the point.

Of course, if the load in the circuit is well below the CCC, you have nothing to worry about.

Are you using compression glands?

 My question is, do wagos need to be fastened or suppported on some way inside an adaptable box? 
 

thanks

If the cables entering the box are fixed securely externally then no.

I believe those aspects are covered in the product standards, and the manufacturer does declare the loading factors and tightening torques?

Interesting question. I wouldn't be happy at a screw terminal having to support too much weight (with the exception of a GLS fitting for which the rose and lampholder are specifically designed for the purpose) 

So, for example, I might not always worry about a terminal block being fixed within an accessory where the cables are partly supported by either grommets, glands or plaster, but I wouldn't like to put one in a vertical run, say in trunking or a round conduit box without strain relief of some sort.

The same things, especially when considering singles in conduit/trunking installations, probably ring true for screwless terminals, though …

In summary:

•  if there's no strain-relief on the cable or wire, and it might be subject to [axial] strain on the connection, you're asking for trouble regardless of whether the terminal (of any kind) is fixed itself or not
• fixing of the terminal itself is dependent on vibration environment, and is quite possibly useless in that environment without strain relief on the wiring also.

Generally agree but see above.
