RE: DIN Enclosure for CBus modules

["James Mitchelmore" <james@xxxxxxxxxxxxxxx>]

I find it quite ridiculous, given the cost of the cbus dimmers, to have
to then hang an mcb of every channel.  Surely they should be robust
enough to suffer a bulb blowing (which as frank says, an mcb aint going
to be quick enough to protect anyway).  As for being able to isolate
individual circuits, no disrespect, but on the odd occasion that you
need to fiddle with a completed installation, just throw the breaker to
the whole bloody lot.

Nothing against the whole ethos of cbus, but when you=92re paying 350gbp +
vat for 4x2a dimmer, you=92d expect it to be little more grown up when it
comes to installation.

Anyway, just my 2d=92s worth on return from the pub so I=92ll leave it at
that.

BTW I=92m fully wired with anytronics 4x5a DMX racks and very happy at a
fraction of the cbus cost (and no extra mcbs!).

That=92s all

It is the recommended practice by Clipsal UK to have MCBs on the output
channels as well as inputs. We have just installed 2 x 8-channel C-Bus
dimmers and a 12-channel relay unit in our new office cabin with all
output channels protected by MCBs. It may or may not be too slow to
react
to a fault on the load but the ability to isolate individual output
channels at a flick of a switch, in my opinion, is worth the relatively
modest outlay.
