Paul, Frank,

Thanks for those responses =96 it was one of those C-BUS issues that I
hadn=
=92t
quite wrapped my head around, and as I=92m possibly just going to install
t=
he
cables at the moment, quite an important one.

Can only speak for CBUS, not any other system...

Cable topology with CBUS is completely free, - you can star wire, bus wire,
or a mixture of both. So it's completely up to you if you want (or don't
want) to put 2 wires to a CBUS unit. Switches have screw terminals that
*can* take 2 CAT5 cables into them, but I prefer to run a single cable to
switch positions, home run back to Node 0 and common them there. CBUS
modules (i.e. dimmers, relays, etc.) mostly use RJ45 sockets, and pretty
much all (in my experience) have 2 RJ45 sockets to facilitate continuing
th=
e
network on to the next unit.

You *can* common the cables at Node 0 pretty much any way you choose, any
convenient terminal block and so on. I believe the best method is to common
up a block of RJ45 sockets on a patch panel, then terminate CBUS cables
wit=
h
an RJ45 plug and use that as a very tidy and convenient connection point.
(DON'T get these ports mixed up with your Ethernet ones though!)

How many burdens you need depends on your CBUS network design. Suffice it
t=
o
say that you need at least 1. I rather suspect that an "average"
UK size
house probably won't need more than 1 however...

I'm not aware of any particular special Clipsal terminal block for CBUS,
bu=
t
it wouldn't surprise me if there was (as you say, for =A3100 of course!),
however, like I already mentioned, any common terminating method is
acceptable as long as the termination is good.
