EIC wago wiring help!

[adslev]

Need help from any sparks familiar with wago wiring, started testing today in a new build hospital, all wiring is wago systems with home run boxes etc... Never came across this system and currently doing my dead tests ( r1 + r2 ins res ) however it seems to be a very time consuming task, has anyone any tips advice on how to go about this as the other testers on site don't seem to familiar with it either!

Nobody? Ok il try an give use all a bit more info! Basically from the dis board there is is what I can only describe as a 3" copex which contains six circuits on the different phases, this then plugs into the pre wired board with pins, at the other end of the copex there is a splitter which then wago's can plug into, the whole installation is modular with all cables being pre terminated so its just a big jig saw, I don't like the idea of unplugging all the ends as this could take forever but at the moment its the only possible option I can think of, I'm sure there's an easier way which is why I'm here! So please don't be shy with your suggestions!
Ps not a bit of conduit or trunking on site just basket and modular wiring, so far I think its a bit of a joke but its only day one and I'm only contracted to the testing, I'm sure the wiring itself would be quite speedy and straight forward

Totally surprised that this type of wiring method has been used in a hospital setting!! I think there are going to be lots of problems in the future, and i'm convinced it will at sometime be replaced with more traditional wiring methods.

Sorry adslev, can't help you, never worked on such wiring systems. The mind just boggles at how long these plug-in pins etc, are going to last in maintaining strong connectivity, especially when/if circuits get near to their current carrying capacities. And if your finding it difficult to test at this stage, what's it going to be like later on for the hospital maintenance staff??

The system are ordered in kits ( bespoke for each installation esentialy plug and play ----------------time is money!

Let's hope this hospital is unlike all the other hospitals then, because as sure as eggs is eggs, ....They will want to change, add, delete various circuits, etc, etc!!!

Are we talking GST8/16 plug & sockets type things???? i.e. http://www.tls-ltd.co.uk/wieland.html

If so they are fairly well built, should last, modular wiring from my experiences and the systems I have used are very easy to mod.

I have worked on hospitals recently where they are doing as you say, all modular wiring BUT it was all pre tested, was just a case of connecting it all.

That is one of the selling points of the modular system, flexibility.

We installed an Apex system in an office in Leeds and after initial doubts, I must say I was well impressed by the quality and strength of the termination plug/socket arrangements.

The real advantage came after the initial fit-out when the tennants erected partition walls and altered layouts etc.

Like it or not, this system, along with off-site modular installations is going to be big over the next decade or so.

wouldnt each lead need to be tested might be best if you made test leads up ie cut plug of one end connect into choc block and do your dead test from this point seems the best way to me

 

[Engineer54]

As i have never worked with these systems let alone even seen one installed or being installed i'll bow to those that have!!... But i think i'll still reserve my doubts until such time as i have seen such an installation...lol!!!!

 

[adslev]

Of course changes and alterations are rife throughout the installation, wards being completely wired and then designers wanting to change entire wards to administration offices, its the publics money that's being spent so why not waste it, still getting my head round this system, its not as bad as I first thought although 4 high integrity earths supporting 9 circuits does seem a bit strange!

 

[Engineer54]

Adslev,

Can you explain a bit further on your comment about the earthing arrangement please??

'' although 4 high integrity earths supporting 9 circuits does seem a bit strange!''

 

[adslev]

I'm trying to find out some more information on the net, from the db nine circuits leave and go to a home run box, 1L1-3L3, there are nine separate neutraland live conductors and only four earths, then at the home run box the earths all linked out and support all 9 circuits, its winsta modular wiring systems but even their own website sheds any light on why this method is used

used apex at large hospital , loads faults ,,,has good points and bad,,,

 

[adslev]

The biggest problem I'm having at the moment is the sparks who have wired the place seem to have just plugged into the handiest circuit, so its very time consuming sorting it all out when everything has been cable tied to the basket, however had the place been wired correctly it would have made for a very speedy install

What type of faults did you find?

We did a large office block in Leeds and the Apex system was impressive, testing was very easy, using Apex plugs connected to a breakout box for R1+R2 and Zs readings.
