Running 12AC over cat6 cable for Skybell HD doorbell

[JK200SX]

I need to power up a Skybell HD doorbell over Cat6 cable. The cable length is approx 12m, and the transformer used will be

I will use all the 8 conductors, ie make 2 pairs each containing 4 conductors. Will this be ok? In terms of conductors, should I join all the solid coloured ones together as 1 pair, and all the striped as another? or should I just make all the blue/brown pairs 1 conductor and the green/orange another?

Thanks.

No problem.

I'd just put 2 pairs together for each leg, i.e. as you mentioned "blue/brown pairs 1 conductor and the green/orange another".

I don't see a problem with it either. Is the Cat6 already in situ? Otherwise I'm sure that there would be cheaper/more appropriate cable to use.

Bell wire or light speaker cable is most suitable.

Agreed.. if the Cat6 is already there and you're not likely to want to use it for something else down the track... by all means, it will work fine.

I used some old Cat3 2-pair for the same purpose years ago.

One single pair is all that is required to power the Intercom.
