RE: Re: DIN Enclosure for CBus modules

["Dean Barrett" <dean@xxxxxxxxxxxxxxxxxxxxxxxx>]

As we are past 1st January '05 - shouldnt you be getting a decent
electrician to do it all anyway ?

You should have Part P compliance, and not be breaking the law. An
electrician could only certify his own work anyway.

A suitable enclosure will have neutral and earth bars fitted to which you
can bring everything together - if you feed with a 20a remember its got to
be bigger than 1mm !!

With your installed feed you will supply the control side of the dimmer and
then loop across to the dimmer side. All neutrals and earths from outgoing
sides will go straight to blocks.

Depending how many circuits you've got, you may find it easier to get a
coil
of 1.5mm Brown 6181Y (single cable) and use this to go from each Dimmer way
1a MCB, and then the other side of the MCB will have your T&E coming
back
from the lights with neutrals and earths going straight to blocks.

I'm no electrical expert - so if the consensus is for MCB's on the load
side, i'll do it !

My only problem is no experience with MCB's/Consumer units - so if I do
get a 2nd enclosure for the CBUS stuff, it's the dos and don'ts for
getting the wiring right.

I have 2x8 Channel Dimmers and 1x12 Channel Relay. So I'm assuming my plan
is :

1. Install a 20Amp MCB in the main consumer unit (B type and 6KA rating if
possible ?)
2. Earth and Neutral to enclosure. This is the bit I'm not sure on - how
to extend these from the consumer unit correctly. I need some sort of
"block" for each one ?
3. Install MCB's for the LOAD side. So, I need 1Amp units ?

OR - I find a decent electrician !

Mine are all protected by MCBs.  Have a look at Mark's Node 0 feature,
or at www.nicklocke.co.uk/Auto.

Yet another spin on bulbs etc..... the fact tha the dimmers always do
a soft start seems to have increased the life of the bulbs in a major
way!  Been in the house since August and, so far, have not replaced a
single bulb.....

I did have a slightly different problem in that the swicth on surge of
the external security lights almost always tripped an MCB.  Following
valuable advice on here, those channels now only switch a contactor,
with the contactor doing the dirty work.
