DNO joint cables then hoy them 3 ft under concrete and forget about them!!! same difference??

Good point...and I regularly bury resin joints on SWA's...they are designed for that.But I was meaning joints on final circuits within the building....which is not the same difference IMO.

have to agree to disagree! if a joint is undertaked to a high quality using maintenance free equiptmnet and correctly installed into fabric i see no problem.

every one has there OWN methods and ways to which i dont question... i just hate digging chock block out of walls covered in tape!!! thats cowboy!

where do you buy your wagos and which kit do you recommend, will be handy for a job i have coming up but have never used them before and would like to get best value for money. Will be using them for some 1.5 t&e but would like to get a good selection to keep on the van.

both hellacon and wago do small packs with a good selection in them. most of the wholesalers keep them in stock now or try this one

Same difference, .....How's that then?? Is the joint not made off correctly, ....Of course it is!!
All direct buried joints, are for want of a better description made off covered and forgotten about as such. But hopfully recorded on the area plan drawing.....

Same difference?? I think about as far apart as you could get !!!!

 

[DurhamSparky]

thats not far short of the price i paid for a FULL contractors pack from bemco!! hhehehehehe!!

unless your at newbury!

To the naysayers - do you actually know what a wago is? Have you used them? I'm telling you, if you put a thin cable into one, lets say 1.5mm twin, and try and pull them apart, I'd put money on it that the cable would snap before the wago failed.

Give them a slight twist and they come out with ease.

Well we do question other peoples methods,everyone on here including you and me....thats not to say one is better than the other,we all have our own ways.
The big problem for me with joints plastered into the wall and not in an enclosure is damp.Such joints will never be damp proof and in a damp wall may result in a potential hazard

 

[DurhamSparky]

i would never put a joint in a wall with out enclousre!! for exact reasons...!! i use enclosures all the time as rule of thumb even inspector said in a wall thats been plastered it needs a cover of some sort to counter the moisture and agressive nature of the plaster mix!

 

[DurhamSparky]

bit of a wiggle i would say!! more that what a cable could ever achieve under its own weight!

 

[rocker]

The helacons I use require some serious twisting and a lot of pulling to get out.... I can't see them coming out of anything unless you want them to.

Try this small company Wagobox Home of The Maintenance Free Junction Box very good will send you a free sample to try out in your home

My 2 cents worth...

the Inspector from Elecsa/ECA talked to me about wago connectors and he was all for them!

I'd agree

i asked the question about plastering them into a wall and his advice was YES they are designed for that and as long as they are protected in an enclosure like a chocbox or similar they can be treated in same way as crimped connections as the effect of moisture from the plaster and also the aggressive nature of the plater may cause damage to the connections!

A crimper can be considered as a compression tool, resulting in a maintenance free joint. As mentioned in 526.3
A wago cannot really be considered maintenance free as the cable can be pulled out and so are vulnerable to vibration. Proper anchoring could maybe fix this issue, but then there is the problem that can arise from excessive overload. Granted these wago's are designed to an operating temperature, but if cables do get overloaded it will be at there weak point where they will likely char and/or snap, which is most likely in the wago. I have seen this before twice already.
I think it's early days with these connections for us to be happy filling them into walls never to be seen again without an understanding of their longevity.

he also said that due to the design nature of the wago they need not be enclosed in an enclosure if say placed in a loft area or a partion wall providing they have been terminated correctly and pushed fully home with no copper on show as per manufactures instructions!

That seems like nonsense as wago say they should be in an enclosure, and more importantly, there will be no fault protection at the connections?

I've been using Wago's for years and have never had a problem
Thry don't pull out, cause hot spots,or break the cables, compered to some of the crip joints if seen over the years there a lot more reliable

They do pull out, and they do heat up. I have done, and seen this happen.

What's a crip joint?
