Don't let me ruin your day, but at the bottom line you own only that which you hold title (not deed) to. Your money, your land, your home- everything belongs to the Federal Government except your vehicles, road trailers, boats, and mobile homes :eek: Unless you're a Naive American that is, in which case you or your Tribe does own the land until the Fed's decide to beak the treaty again :mad:

Just stop paying your taxes and you'll find out who owns your home and property. :eek:

Hi Semi-Retired.  I have a cold water pipe that carries all the house current that should return on the neutral.  My buddy is a master electrician and measured a high current on the ground.  He put his current clamp meter on the water pipe and saw 3.14 Amps.  We then proceeded to push more current to the neutral by adding more load via space heaters to one side of the service.  The current climbed to over 13 Amps!  He told me to call my utility.  They came out, tested at the demarc and said the service was fine and any problem must me mine.

My question is what is the load test that most utilities do to verify a good connection?  The said they did a load test however if they didn't stress the neutral, they would never see this.

My service voltage is perfectly balanced, after loading up one side to get the 13 amps on the ground we saw a drop of 4 volts on the loaded side.

Best I can figure, my neighbours have great connections between their water pipe and the utility neutral and I have no issues, however I am a HAM operator and my noise that is pretty much broad band is a 60 Hz hum all the way up all bands.

Thanks for your posting, it gives me hope someone out there understands my challenges.  I attached a picture of the amp meter for your viewing enjoyment.
