I'm fixing up my dust collection ducting, using 6" (150 mm) PVC Sewer pipe and fittings. Into almost every joint I have screwed a high copper alloy screw, and I have wrapped these screws with some stranded 14 Ga extension cord wire (bared at the copper screw terminal).
My objective is to lower the static electricity charge inside the pipe and outside the pipe.
Is the copper wire OK at that light gauge, or do I need solid 12-3 for more robustness.
Thanks
