It's not an NEC issue, but let's say I specified an insulated bonding backbone for my telecommunications spaces. Then let's say my contractor decided to strip off the last 18" of insulation for the leg between the EMT and the ground lug to save the trouble of running an additional bonding conductor back to serve the conduit. The wire exits the conduit through a grounding bushing. So, the wire is insulated while in the conduit, but then bare and exposed for 1-3 ft. Who can weigh in on this? I swear I found somewhere a distance limitation on bare ground wire in telecom spaces and the rationale for insulating said wires, but I cannot locate this. In my mind, stripping more than the minimum necessary insulation from the wire results in it no longer being an insulated wire and it should technically be replaced.
 
Why would it need to be insulated at all if it's bonded to the conduit? Is this a TIA requirement?
 
It appears that insulated is required by TIA. The following is from the Mohawk website and is a partial synopsis of TIA 607:

BONDING AND GROUNDING COMPONENTS
Bonding Conductor for Telecommunications This conductor is used to bond the TMGB to the service equipment (power) ground which is in turn connected to the grounding electrode conductor.

There are three important design considerations to remember about bonding conductors:
  • The copper core conductor must be insulated and be at least No. 6 AWG in size
  • These conductors should not be placed in metallic conduit. If this can not be avoided, the conductors must be bonded to each end of the conduit if the run is longer than 1 m (3 ft.) in length
  • Ensure that bonding conductors are marked appropriately by using a green label.
 
Answered my own question. NECA-1 covers the excessive insulation stripping and the other part I was concerned about turned out to be a requirement for the telecom primary protector conductor to be min. 12" from DC cable, switchboard cable, and high frequency cables.
