My understanding is that only ONE burden is to be present in a CBUS
Installation...You are allowed to have approx 3 devices with clocks
enabled......

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
the
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
with
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
to
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,
but
it wouldn't surprise me if there was (as you say, for £100 of
course!),
however, like I already mentioned, any common terminating method is
acceptable as long as the termination is good.
