ground wire

[champy]

Is thwn ok to run to ground rods i do not see where thwn can be indirect contact with the earth soil.

 

[FionaZuppa]

hmmm, for what purpose are you doing this? ground rods sounds like bonding, which is usually #8 or bigger bare copper.

is this your 1st use of wire?

my inclination is to say no under NEC, but maybe yes if its the right color and used as a tracer wire not connected??

The insulation type is basically not relevant as a GEC can be bare. What is relevant is whether you are talking about a copper or aluminum conductor. Aluminum conductors cannot be in contact with bare earth and IIRC must be terminated like 18" above ground.

what color do you think it should be?

 

[jumper]

what color do you think it should be?

Anything but white or grey.

if its used for bonding grid, for say near pools, it cannot be insulated. only the egc will come to pump insulated.

what color do you think it should be?

as a tracer? red for electric, blue for water, yellow for gas.

No, he meant the complete GEC color

Conductors used for direct-burial shall be of a type identified for the use. Whatever that means. So, I would say that THWN looks good to me.

can i bury a 2 CCC cable marked for direct burial along with a #6 bare copper out to a sub panel 100ft away, and, use that bare copper for EGC?

This thread is not about an EGC.

exactly the statement i was waiting for, i just had to lead some
right, so it doesnt really matter

250.62 #8 copper #6 aluminum min

if it is very wet salty soil, like ocean front property, i would perhaps choose direct burial rated. southwire makes #8 copper tracer in 30v and 600v, way cheaper than other direct burial rated wire.

insulated or bare. any insulation of any type does help protect against corrosion. so THHN THWN is ok. i guess the color should be green?

And none of that has anything to do with the OP's question so if you want to talk about something else start a new thread.

And back to the GEC discussion at hand, what makes you think it should be green?

it does have everything to do with OP's Q. did you read the Q ? THWN is a protector, good enough for 250, etc.

because world standards use green or yellow striped green for earthed/ground.

why use red?

 

[roger]

why use red?

Because the NEC allows us to.

No it doesn't, you need to read the definition of Equipment Grounding Conductor verses Grounding Electrode Conductor.

doesnt 250.62 say "grounding electrode conductor" ? or is it written in chinese and my translation is off?

 

[roger]

doesnt 250.26 say "grounding electrode conductor" ? or is it written in chinese and my translation is off?

250.26 has nothing to do with the conductor the OP is asking about.

With that said, we're not going to play your games, we are talking about the GEC and if you want talk about something else, I'll say it again, start another thread.

Yes, but you edited after my post, you originally stated 250.26.

Fantastic- now where does it say anything about the color of any insulation?
