Cat5e cable should be run through the installation in electrical conduit, either metal, non-metallic, rigid or intermediate, wherever possible. Should conduit not be available or impractical, cabling running through frames or beams must be a minimum of 25mm/1inch from the nearest edge of that structure. If the frame or beam is metallic, then the cable should be protected by a bush or grommet. When routing cables around the installation, care must be taken to prevent kinking and trapping. Any cable ties used must not be tightened any more than is necessary to hold the cable in place. Always re-check the colour code of the Cat5e cable connections to ensure they are correct.
