Good Morning. I recently installed a US Tower HDX589. I also installed a number of 3/4" 10ft ground rods. Then cad-welded #2 stranded copper wire to the rods. I am now trying to determine the best w
Came off of a central point of the ground system then ran 3" copper ribbon (From Georgia Copper) to a cross bar on the tower base then used two copper palates to sandwich the assembly ...a picture is
NEVER let copper come in contact with galvanized metal. Always use a transition metal. A past WILL NOT SUFFICE. 73 Jim W7RY _______________________________________________ ___________________________
How about using the aluminum lugs? Would that be ok between the copper wire and galvanized tower metal? Eric K2CB NEVER let copper come in contact with galvanized metal. Always use a transition meta
Ok, then what is the best method to connect a #2 stranded copper wire to a galvanized steel tower? Eric K2CB Nope, aluminium and copper hates each other... Actually, aluminium is in relatively good r
Good practice is to sandwich a strip of stainless steel between the galvanized tower leg and the copper. I applied a coating of Penetrox to the stainless steel. I bought my stainless steel on line. M
And what NEC code are you reading that allows stranded copper for grounds? How about the grounding kits that are readily available to make ground connectioins to the tower leg. Rohn part number BGK o
No one says that you can't use stranded wire for grounds. The reason not to use stranded is because when you get corrosion at the connections it is difficult if not impossible to properly clean the s
First let me say that I bought my HDX-555 used from an estate so I don't know if it was original equipment or not but my "T" base had threaded lugs on two of the arms. The third looks like it had one
NFPA 780 for lightning allows stranded. So does NEC, if the bonding conductor is of sufficient size. (note that Art 820 (cable TV) Antenna "grounding" is AWG14 or bigger, but Art 250 "bonding" of gro
