Post Subject: Drain/Bleeder GroundPosted by Paul S on: 1/13/2021
Good for you, Jarek! As for the very specialized (and not always needed...) "bleeder" ground, it has been my experience that it has worked best when it is a "stand alone" copper rod driven at some distance from the service ground. I run a 12 AWG magnet wire from the system, through the wall, to a rod driven near the house foundation, outside, over 60' from the house/UFER ground. I realize this is not always easy or even possible to do in certain cases, notably apartments; but this has been my experience. Of course it is possible to measure noise on the "house ground" with the system running, and in rare cases noise is low enough that it's a non-issue. In your case, it seems unlikely - intellectually - that the house/system ground will be quiet with the PP installed and running; but if it is indeed quiet with the PP then you can consider yourself lucky.
Best regards,
