I've heard that the "loophole" that's allowed Alarm, Data, & other LV types to get away with coming in after-the-fact (inspections) to do their work is being closed with the 2002 NEC. Is this true??
Sure would be nice. We do our best to comply with the codes, and make a safe installation, only to have these guys come in and blow a hole the size of a small dog through a firewall to install their tiny cables after we're done. (These fellas were pretty sloppy, ehh?) Scott (Electure)
wiring is all the same to the general public, so these sorts give us all a bad name. I thought art 800 builds on the first 3 chaps. of the NEC, it does not exclude it as far as i have read ( but i read slow)
About time for that loop hole to be closed. Too many inspectors tell me that security, telco,and TV are not my area to inspect. Can see junk like this in just about every commercial building around here. much worse if there has been tenant changes.
