Thanks Tim.

Looks like (from what I can see of the mounting clips on the back) these
ap=
pear to mount horizontally on the DIN rail, such that cable entry is from
t=
he bottom... which kinda takes up way more space than if there were one
jus=
t like this which mounted vertically... they also do 8-way in non-DIN
mount=
ing flavour, which gives me enough ways, but doesn't do very much to aid
my=
spaghetti in the enclosure problem... unless they could perhaps be panel m=
ounted...

Hi Paul,
In industrial control panels you'd typically use something like
these:https=
://www.phoenixcontact.com/online/portal/gb?1dmy&urile=3Dwcm%3apath%3a/gben/=
web/main/products/subcategory_pages/Installation_terminal_blocks_P-15-01-06=
/ff4c4ab3-7bac-430c-bdd1-46cfa5b5f3e2
or these, which are smaller:https://www.phoenixcontact.com/online/portal/gb=
?1dmy&urile=3Dwcm%3apath%3a/gben/web/main/products/subcategory_pages/Mini_a=
nd_micro_terminal_blocks_P-15-01-10/5ebbe9ed-a249-41bd-ac1c-20313e51a149
You can get accessories which allow several blocks to be
commoned-together.=
If you were really tight for space I guess you could use a combination of =
these, and the lever WAGOs you linked to before (I've used those WAGOs in
t=
he past too :) )
Some alternatives to the Phoenix Contact blocks here too:http://cpc.farnell=
.com/webapp/wcs/stores/servlet/Search?st=3Dscrew+terminals&catalogId=3D1500=
2&categoryId=3D700000031004&langId=3D69&storeId=3D10180
and these from Weidmuller:http://uk.rs-online.com/web/c/connectors/terminal=
-blocks-din-rail-terminals/non-fused-din-rail-terminals/?searchTerm=3Dweidm=
uller+terminals
HTH,Tim.

As I go about installing CBUS modules, I'm always slightly frustrated by
th=
e untidy spaghetti of wiring that results, despite my best efforts to be
ne=
at & tidy.=20
the main problem is the number of commonned connections that need to be
mad=
e in close proximity to the module... Earths aren't so much a problem,
sinc=
e there is always an earth buss-bar in any standard electrical enclosure.
H=
owever, the Neutrals all typically need to be commonned up as well...
=20
In the past I've used chocky-blocks, but I pretty much hate those... ugly,
=
awkward to use etc... more recently I've been using WAGO terminal blocks
li=
ke these: https://encrypted-tbn2.gstatic.com/images?q=3Dtbn:ANd9GcSCbpKanS3=
Jh3CjIpCvLpkcLy5lTBf_whsi5CQW3ElVkunM6at7
=20
WAGO make a couple of varieties that are readily available here at my
local=
suppliers, but all have some drawback... the lever type as per the above l=
inked image only go up to a 5-way... that is rarely enough... - even for a
=
4-channel CBUS module there's usually 6 connections to make. WAGO do a
6-wa=
y block like this: https://encrypted-tbn0.gstatic.com/images?q=3Dtbn:ANd9Gc=
R4YO7SWhVI4O6OgpZJ_ppJk1UweNqSTqeGl2DDRSxftJJtSpkS but this one has the
dis=
advantage that they are rubbish with stranded cable.. the insertion force
r=
equired means stranded usually just crumples up in the hole without
forcing=
its way through the jaws of the clamp inside... they really only work with=
solid T&E cable, but I don't always have the option of using that
inside t=
he enclosure, as it depends on the appliance I'm wiring up to the module...
=20
And all of these still leave spaghetti as they end up hanging around loose
=
inside the enclosure with half-a-dozen patch wires snaking off to
different=
ends of the modules...
=20
There must be something better... what I'd really like is something with
as=
much capacity as you normally find on the Earth bus-bar, say 10 or 20 wire=
terminals (and the ability to daisy-chain more bars to extend that), and w=
hich can be fixed into place somewhere inside the enclosure... perhaps a
te=
rminal block that can be DIN rail mounted next to the module itself? is
the=
re such a thing?
=20
So come on folks... how you wire up mains HA modules & keep nice tidy
wirin=
g?
