I was pleased to see this document because it shows AV technicians how to install their systems to work properly while complying with NEC. Electronics technicians have little understanding of power wiring requirements. I have had confrontations with electronic system installers who insist that their equipment will not function if it is installed to comply with NEC! AV and telecommunications grounding must be handled carefully to avoid operational problems. For further information on telecommunications grounding details, refer to the Telecommunications Distribution Methods Manual published by BICSI. Jim Cook
