posted some pics of my install here, if anyone is intrested

Looks great.
I for one would be interested in seeing others C-Bus installations, both private and commercial. Maybe some links to some images??

Question About PCI

Hello

Just a question to why you still have the burden clip in and haven't programmed a unit to take over this role?

Otherwise it great to see other installer jobs

Will look at posting some of ours

 

I don't know how regulations stand in Iceland with regard to segregation of ELV and LV wiring but Iam still somewhat concerned with how close the C-bus wiring and mains are to each other.
May I suggest putting C-bus in a trunking within the Distribution board

 

in the shot with the cni, analog output and power supply, there is a gray block that looks like you have the c-bus cables plugged into - what is that

Great to see examples of other installers work, nice one Arnis!

I'm not sure that this would pass inspection in Australia though - I suspect that ACA would require more seperation between the mains and Cat 5 with the cables having to be securely fixed. The second picture shows standard gray (not 240V rated) cat 5 being used.

Here's one I did earlier before it went up on the wall, it looks a lot simpler than Arnis's as I have all the MCB's and RCD's in a seperate cabinet. I have always mounted them seperatly what do others do?

 

Yes Islotation is an issue and the reality of wiring up C-bus switchboards is that it is a challenge to meet the wiring and ACA requirements. However with the exception of the gray Cat 5 used this was not too bad - remember that wiring codes differ around the world and what is ok in some countries is not in others.

 

Is the Clipsal pink CAT5 cable not rated at 240V?

My regs knowledge is from the UK, and the rule there is basically that all wiring in an enclosure has to be rated for at the higest voltage within the enclosure, and thus as long as the CAT5 is 240V rated or greater it can be treated no differently (in routing terms) than wires carrying mains...?

 

c-bus wiring

Hi guys and thanks for all the replays.

This is infact my install in my own house, so I am not a installer in that sense, but am doing my own work my self.

I regards to the cbus cable in the main switchbord i just use the Pink cable, but it?s is difficult to have it compleatly seperate from the mains wires, beacuse the lack of space, but as it?s mains rated I was thinking it was ok.

as for the smaller box with the CNI + analog module, this is where I have all the cbus cable runs meet, I use standard CAT5e for runs to switches and sensors, the main reason is that In Iceland i have to have all cbus stuff shiped to me from the UK or Australia, and I did not want to pay the shippin fees for a whole box of cable, and figured I would be ok if I used the gray outside the switchbord.

also in the samller box I need to tidy up the cables better, when I find the time

also somone asked what the gray unit was that all the cbus cables wear connected into was, It is an old "passive hub" from an old IBM cabling system
basicly connects every pin togeather and thus works well in connecteding all cbus runs.

 

In your picture above I see a an issue I see with Cbus gear that has the new screw terminals. In Terminal 3 and 4 of TOP dimmer and terminals 1 and 2 on the second Dimmer. There are only 2 screws in these terminal blocks. I have noticed that unless you are quite carefull the terminal block (the green part) moves. You have to be carefull not to over tighten. When I first saw this happen on an installation I was worried that the solder joints on the dimmer might have cracked.

CIS guys... is this issue causing any dimmers to be returned or is it just the green plastic piece moving ??

Out of all the Clipsal DIN enclosures I have to say that the THIS ip rated enclosure is the best. It has 3 neutral Bars to isolate the neutrals for 3 circuits for 3 dimmers. Has a big Earth. And lots of room top and bottom. Clear doors (to see the lights !), dust/moisture resistant
All other clipsal boards are deficient in these areas as they are switch boards and not CBUS equipment mounting boards. THe only only disadvantage of this board is it is surface mounted and can not be recessed into the wall.
CIS please bring out a Cbus Friendly Board.

Sprung!

Well spotted Charlie! We did notice this before we finished off and rectified it by putting in new units and being careful when doing up the screws. But the photo was too good to erase - I got the light just right, no glare, no shadows. This was the first (and so far the last) time we had experienced this problem with the terminals (the units and channels still work ok!) and we put it down to badly set tourque setting on the power driver

 

cbus network wiring

From the paperwork I have read on the cbus network it seems you have two utp cables going to each switch, to loop the switches together. Is that correct ?

I like the idea of Arnis' a passive hub . Please confirm if I used this methiod, the rj45 connectors would be wired identically, I would have just one utp cable going to each switch , and you would attached the same coloured pairs to the +ve and to the -ve for all switches
