Wiska CU re-locator?

pc1966 · Jun 17, 2022

When deleting TLC adverts I stumbled across this new product:

Looks a good idea, but if DIN terminals then are the G/Y ones all linked via the rail? Electrically good, but a problem for testing.

TL;DR Anyone seen the CU relocator in the flesh?

Interesting. I might have a look at one of those.

I've fairly recently got a 3D printer and have been experimenting with designing DIN rail mounts and 221 holders, printed in ABS.
(I'm in process of designing mounts for the larger 6mm version)
I want to incorporate some holes for zip ties top and bottom.

So far only used in my own house!

Looks pretty useful.
You would probably need 2 of them for most consumer units, as it looks like it takes around 9 or 10 twin and earth.
I'm afraid I haven't got any first hand experience to offer though.

Don't think I've every seen an earth din connector that wasn't connected to the rail, even before Wago appeared.
Previously done with a screw, not just contact.

I am impressed!

It's about time some body tackled the
Frustration on moving a boards, I had to
Alter one last year. Could not get a din rail any where.

That is what led me to start 3d printing. Screwfix sell the din rail in 1m lengths for £2.50

if the earthing is a problem for testing, switch the din rail for a plastic one.

I’ve used one of these on a job recently. They are pretty good and leave a neat finish. However, they have some restrictions. As someone has pointed out it only allows for 10 T&E connections. In most cases, if you have 2 ring circuits, that’s 4 of the connections gone. There is also a restriction in cable size and found it couldn’t be used for a 10mm shower supply.

I did find you can move things around and used Wago connectors for some circuits which you can still tuck in the box.

To answer your question though, nothing is linked. Just in one side and out the other.

Wiska are doing one as well prebuilt with din bar and box. It seems fixed, i.e. not interchangeable so only useful in specific low population CU changes.

Nick Bundy did a video on it a while back -

(about 4:20 for the bit) - and had to cannibalise two because he needed to move one of the larger contacts.

Does show that there is no din rail connection when he has one out though.

He also did one with the standard din rail 2 years ago -

Looks like it would be a good option to move an old Wylex wooden board, but with any modern board there will likely be too many circuits - I wonder if there is a technical reason for them not doing a larger one, or maybe if demand is there they will bring out in time. Ideally they'd sell a variety of widths and then the connectors separately.

The last time I moved a Wylex fuse board a short distance I used Wagoboxes (labelled), within a suitably sized adaptable box, which seemed to work fairly well if a bit overkill...

I must admit I prefer to use and the overall look of the traditional din rail connectors

You need a lot of DIN rails to pay for a printer!

More seriously, are they and more or less crap than paper printers (where they never work when you need them as paper jams or ink out or just bitching about some error that was not there last time, etc)?

I actually got setup for less than the price of 3 of those wiska kits! I was very lucky though - after much patience on ebay I landed a £500 printer with over 10 x 100m rolls of ABS filament 2nd hand for just over £150. The filament alone would have exceeded that cost.
They are a lot less crap and much better engineered than paper printers. Printing ABS on a heated bed has a slight learning curve but in general if the first layer sticks the rest will be fine. Printing PLA (lower melting point, would melt in a dishwasher) is a lot easier as it's 'sticky'.
Getting the bed level is the main thing. Overall it wasn't as hard as I was expecting it to be. Patience is needed as 3d printing isn't quick - each wago holder takes 40 minutes!

(I did read something once about every public library in Scotland having a 3d printer- don't know if it's still the case!)

Isnt the problem with that though the cpc's are connected to the din rail, meaning you make effectively an earth bar, which means like your r2 and r1+r2 readings will be all out? I know you can use the none cpc versions to avoid this but something to be aware of..
