Graham,

This is not supposed to be a good idea because the mains interference will generate noise in the CAT-5 cable.

 

Crossing mains @ 90degrees is okay, but long parallel runs should be kept at least a foot apart if possible.

Having said that, it will probably depend on the application as to whether or not it matters.  For PC networks obviously no noise is good noise - for IR distribution, it may not matter.

I get some noise on my phone circuits due, I _think_ to the electrician ignoring me when I told him to keep the CAT 5 away from the power runs to the bedroom.  Can't prove it of course & not enough knowlege of the stuff to know if that is actually the case, or if I've just cocked something up....

 

I'm sure Mr Doxey will be able to give u a more informed response.....

 

Tony
