There are no hazardous voltages with IT cabling so why on earth can t a conscientious tradesman turn his hand from heavy current to this new kind of child s play Trouble is it s not child s play and some very expensive lessons have been learned by electrical contractors unaware of the intricacies of voice and data cabling.
