Main problem when voice or data cables are run too close to 240v A.C (In Oz) or above(415v) is EMI -Electromagnetic Interference -If separation issues are ignored ,equipment may work quite well and even test OK while there is no load on the power cable.But turn on a welder,Bench saw etc and watch as the PC's attached to the outlets at end of these cables start to crash,digital system xtn phones start having heart attacks and watch the tech who ran the cables without separation, start headbutting the concrete floor.He has just cost himself heaps of time and more importantly, dollars ,having to re-run all the cables,which of course are now too short and will all have to be totally replaced.
MAINTAIN YOUR SEPARATION AND MAINTAIN YOUR SANITY!!
