    There has been information provided that some cat 5 cables can alter their characteristics dramatically. The issue being that when there is a rise of just 4 degrees the voltage drop increases to a point that C-Bus becomes unstable.
    These cables are stranded pink cat 5 and not sold by Clipsal.
    On Changing the cable to the Clipsal Pink Cat 5 Cable the install became stable and temperature variation had little or no effect on volt drop.

    Sounds extremely bizarre.

    Maybe it was not actually Cat5 cable at all?

    Given the low data rate of cbus, it is extremely tolerant of sch things as the cable used.

    Something like that, a small temperature change having such a big effect.... sounds like a good story.

    Have you actually seen this, or just heard it on the rumour mill?

    Believe it or not I used ferrules on all of the terminations (they look like aglets for shoelaces) and all my joins were done on 2-pole commoning blocks from Krone. It seems to matter more if your connections are tight. Obviously stranged gets a little 'hairy'.

    I got up to 97 modules on the same network and I still had to run a burden. I was using the clipsal pink cable.
