Star Grounding and the Home

local codes need to be checked, see what the tlelecoms are doing. Then there are some books on the subject and a few military studies. I like a star on both ends.

Watch out for grounds on water pipes. They can be a serious problem if you make a mistake.

1: Maybe i have misunderstod, but here in Denmark we can have 2 ground rods. One for the house installation and one for the hifi (if made correctly)

2: Noise ALWAYS travels the shortest way to the rod, then it can spread to the rod with lowest resistance and it also spreads to the rest of the system on its way to the rod if the grounding in your hifi system is not made correct. (noise is not so easy to get rid of)

3: If you connect your isolated ground wire to your house rod, then you can be sure that noice from house appliances get to your hifi system.

4: Make a seperate rod for your hifi and a isolated wire to the rod. Then take a ferrit core an clip on the wire the first place it is connected to another groundwire. The hifi rod can actually recive noice from other houses in the area if your rod have the lowest resistance in that area.

You can overdo the ferric core (too much) becaurse: the bigger ferrit core, the bigger impact on the total resistance. Just try out how manny ferrit cores you want on the isolated ground rod wire and listen. When the music starts to sound borring, take some off again. You can do this on the hot wire too. In my experience it is not nessesary on the neutral wire. Unless you live in a industrial area, but even then....

Do this first and you have a solid "platform" for the ground rod in your hifi rig to "build further on" (sorry for my english)

In the mid west and Sierra's where there a lot of lightning strikes you can have 20 ground rods hooked to lightning rods they just all have to be bonded together, same for your stereo system.

This is on the principal of marine grounding. We called it a star marine ground but it is pure marine tech.. Try fixing noise issues on a houseboat plugged into a dock AC supply..It's ALL marine ground (star). The boat is fiberglass, but you still have to share a common ground with an onboard generator, appliances and DC water pump motors.

Everything has to run it's own ground wire and it cannot be broken or spliced unless it's in an explosion proof box. You can use a common block but it needs to be bonded also to the hull if it metal.  In brackish water (the ocean is a hugh battery) You need something for the electrolysis to EAT other than the metal on the boat. Grounding bars!! AWAY from your onboard star points. ALL threads have to use Never-sieze.

I worked on sea going rescue Tugs and fishing boats every now and then for Cat.. They can't break and they can't catch on fire.. What puke buckets.. Working in rolling seas in a foot of bilgewater and friggin' rats askin for something to eat. YUP I miss that job.

I hate seals too, they are mean.. Look at the cute seal, sea going squirrels if you ask me.. Fisherman hate um..

In the US you can have as many ground rods as you want. The trick is that they must be electrically bonded together.  The issue is life-safety and that the +- 120 VAC is referenced to it.  If you have a different ground, it's no longer the zero point, and when a short occurs you are no longer guaranteed it will be at 0.

What about devices like the Puritan Audio Labs grounding Master?

You drive a second grounding rod in the ground and run a wire from that rod to the Puritan Audio Labs grounding Master and from the grounding Master to the ground on their conditioner. Are there any issues with this?

Thanks
