Re: Cabling Question

Hi Simon + Tony

                        I was under the impression that cables should not be run in parallel .I recall reading something refering to electrical cables crossing telephone cables should cross at 90 degrees. In the ideal situation it would be nice to keep them seperated but you would be pretty unlucky if you did have problems if they are only in close proximity dropping down to the switch.

Cables running parallel to each other shouldn't induce voltage - induction
happens when wires cross.  Shouldn't be a problem for basic switching but
induced noise can cause problems with IR circuits.  Try and keep any mains
and LV cables at least 50mm apart.
