Hi, I'm new to this forum, long time reader and any help would beappreciated.
I'm on a job where my company has the structured cabling contract.Another electrical contractor has the contract for the cable tray andsleeves in the cable tray system. They put 4 inch EMT with push-onbushings through walls about the cable tray. The specs for the jobstate "short sleeves do not have to be bonded". So therewas not a question about the push-on bushings. Now we have pulledcable on about 1/3 of the entire project (800,000+ sf job and 2million feet of cable). theelectrical contractor is now going backand drilling 1/4 inch holes and using stake-ons with 1/4-20's throughthe side walls of the conduit to bond to the cable tray. In theprocess they have drilled through some of the cables that wereinstalled already. In the comm. rooms they are using ground lugsdrilled through the side walls of the conduit. Is this a listed or anacceptable means of bonding EMT for communications or any othersystem for that matter?
