Are they necessary when connecting the ground wires together? I can see why for CCC. Thank you for your help.

I would say yes only because it helps keep the joint from corrosion.

I never saw the point in twisting bare copper together and then putting a wetherproof wirenut on the end

If you understand why it is necessary for CCC then you should see why for the egc. Loosing a ground is more dangerous then loosing the CCC. Safety here not functionality-- the egc is very important to be kept in tact.

:-?


I must ask, if the connections require the protection i.e. underground etc.
why wouldn't you treat the ground wires the same as the CCC's

why can you run a bare copper wire to the ground rod?

Because one does not have to worry about the resistance buildup due to corrosion within the splice, as the GEC is not permitted to be spliced, unless it is of an irreversible type.

what resistance buildup this is not a current carrying conductor? why would just the splice corrode?

So you can use rmc in the ground correct? You can use the conduit as a grd. correct? So should you coat the whole pipe in silicone? I'm not tryin to be a smart a#%. I'm just trying to understand. What about a grd clamp direct buried? Should that connection be dipped in silicone?

You lost me....what does the absence of current have to do with corrosion?

Unless some prevention was used, why would the splice not corrode?

Is that measured in hours, days, weeks, months or possibly longer? ;)
