In the 2008 NEC book, Article 800.93(A) states that com cables entering building must be grounded or interrupted by an insulating joint.  I install CCTV systems and usually install between 8-40 cams per job.  Can anyone advise as to how I would ground those cables (and where to get the grounding blocks for a large # of cams) or where to find an "insulating Joint"?  I can find grounding blocks for type F connectors and single blocks for BNC, but not any multi cable blocks for BNC connectors.
Thanks
Dave
