Anyone have recommendations (tested/practical is best :-)?
The APC Protectnet PNET1 and PRM24 seem quite nice and not
too expensive --
if they work....pros? cons?
It sounds like you're either out of NEC, or, you are grounding them
to waterpipe. I believe NEC calls for grounding via earth. You
could strike some rod into the ground several feet deep, attach
to the pipe with conductive screw+locknut+washer, and a proper gauge
for distance cable. Theoretically, that should solve your problem.
What did you electricians say?
