Pull string... (actually he used green THWN) When he left, I re-did it correctlyDid he use mono filament?
Your obligation ends with the installation of an intersystem bonding Termination.
Since this is designed for installation in a conduit run you only need to use a male thread adapter on your PVC conduit end to keep the protection of your Grounding Electrode Conductor (GEC) continuous. Install this in the run of PVC conduit which protects your EGC and the center screw will bond the GEC to the 6 grounding terminals. Insert the bonding conductors that you disconnected into the ports and tighten the green screw to spec taken from the installation instructions.

Green is not a code compliant color for a Grounding Electrode Conductor because the US NEC forbids the use of the color green for anything other than Equipment Grounding Conductors. You can use any color except white, grey, or green. The customary practice is to use a bare conductor. Most inspectors will not bother you about this but using green for the GEC is a violation of
250.119 Identification of Equipment Grounding Conductors.
Unless required elsewhere in this Code, equipment grounding
conductors shall be permitted to be bare, covered, or insulated.
Individually covered or insulated equipment grounding
conductors shall have a continuous outer finish that is either
green or green with one or more yellow stripes except as
permitted in this section. Conductors with insulation or individual
covering that is green, green with one or more yellow
stripes, or otherwise identified as permitted by this section shall
not be used for ungrounded or grounded circuit conductors.

Lol of course green is okay for a GEC.
A GEC is not one of those prohibited conductors.
That changed in the 2005 cycle, up till then the wording did pretty much forbid it for the GEC
Thank you. It's about flippin time! I never got called on it but I was on crews were the foreman was ordered to change it. What a bloomin waste of time.
Well not so fast, the thing is the telco/cable/coms utility had clamped their little ground's all over the old service equipment that we removed, so in their opinion (and the inspectors) we touched it we removed it, we deal with it.
I just did not know it was a NEC code requirement for someone to do so.
The ground straps could not re-attach the same way, so we just left them hanging in the wind, my bad.
The inspectors feel that even if there is not service a hazard exists due to the parallel path of existing coax and the neutral to the pole, and I wont say completely understand why its an issue if there is no active phone or cable service.
Not to mention the main issue was communications utility has a ground rod on the other side of the building we ignored (and the inspector happens to park there) . As Ben pointed out article 250 dot something requires all electrodes present to be bonded together so we had to run a #6 to that.
My PM was trying to call the coms utilities (Verizon Charter et al) and you simply cannot get anywhere fast without an 'account', and one of the stores was vacant so there is no account so we just had to do it to get er done.
All the best

I'm well aware of that.
Think you can convince a few inspectors? I've had some that insist I must mark a (non bare or non green) GEC with green coloring. I've told them NEC has no color requirement for GEC's but they were not interested in hearing it.

I kind of agree it is acceptable, but not required.

That's what supervisors are for. Don't be afraid to climb the food chain.

I'll have to check that out. I know I've been asked to mark GEC's with green after 2005 NEC.

If they just suspend service via software means vs physically disconnecting the cable, you still have same paths on cable or it's shield
Which is how such services are typically interrupted for non payment, cancellation, etc. They just block your address on the system, which with the way things are so interconnected these days it is usually called an IP address assigned to your receiving equipment that gets blocked

In fact it is highly recommended. Everytime I see a rabbit I think aww por thing, so cute but so tasty to so many thingsThat's what supervisors are for. Don't be afraid to climb the food chain.

I think that until or around '05 you had to use green for an equipment ground but nothing said you couldn't use it for a hot.
Grounding requirements for various communications systems are contained in Chapter 8 of the NEC. Maybe not something the electricians often deal with, but if the inspector want it done "to Code" they can point to Chapter 8. Maybe time to call in the low voltage guys and let them deal with it.

No, prior to the 2005 there was no rule that prohibited using a green insulated conductor as an ungrounded conductor. The 2005 was the first time the following language appeared in the code.
While many read the requirements to identify the EGC with the color green as a prohibition on using the green color for ungrounded conductors, the code did not actually say that.
