Greetings,
As I install my new tower, I was dropping some ground rods next to the
base and acquired some #6 solid copper wire to make the connections (or so I
thought).
When I went to cut the wire I found out that it had a hard core, most
likely steel.
Sounds like copper clad steel (aka Copperweld)..
How much did you pay for the wire (per pound) compared to the price of
copper? (about $2/lb today) That will give you a hint, 100ft is about 8
pounds, so you'd expect it to be at least $16. Home Depot is selling 50
ft of AWG 6 for $37 (which is pretty expensive) or 500 ft for $237 ($6/lb)
I'm not sure this is plated as the outer copper ring is a substantial
portion of the cross section.
40% copperclad steel would have a moderately layer of copper AWG 6 is
0.162" in diameter and 1 ohm/1000 ft.
AWG 10 solid wire is 1 ohm/1000 ft and is 0.1" in diameter
So the cross sectional area of the copper for 40% CCS should be about
the same as for AWG 10 - it works out to cladding thickness of about 17
mils (out of 162 mil diameter) - so that's pretty thin..
Is that what it looks like?
As I'm not familiar with the applicatio of this type of wire I wonder if
it is acceptable for the grounding connection between the tower and the
ground rod?
Thoughts or comments please.
Thank you.
