Sizing of bonding conductor

[bluecollar84]

Hi where can I locate how to size properly my bonding conductor from the intersystem bonding termination to my telecommunications main grounding Busbar TMGB ? Thanks

I've never seen anything to do with telcom, especially grounding/earthing and bonding, that wasn't speced on a set of plans.

The plans show the locations of the telecommunications busbar but no sizing requirements for conductor sizing . Is it in the 2017 NEC anywhere ?

If this is an actual telcom job with a real set of plans conductor sizing along with a whole lot of other specs is on the plans somewhere.

So the NEC does not have a code on sizing of this conductor then ?

Article 800 - Communication Circuits

Specifically, 800.100(3)

No smaller than 14 AWG, no larger than 6 AWG. No specifics on how to arrive at what size to use.

You have asked the same kind of question ten different times. What kind of job are you working on?

And he said these were homework questions in another thread so he really needs to talk to his instructor.

I usually see #12 but I guess it depends on the system
