If all of the components are plugged into the inverter ...

In Reply to: RE: Ground filter with a dedicated grounding rod posted by Ric Schultz on August 16, 2022 at 15:39:31

how is the house wiring involved with the system in any shape or form?

And if that ground post is not needed and one lets the whole system float it would seem no grounding rod is needed. How is his system connected to the house at all even with the ground rod connections disconnected?

I guess I am confused by the need to ground the chassis to earth.

I am glad to see mentioned what his power draw is.

I am sure the PURITAN AC filter is good but I do not use plugs - I hardwire to copper connector blocks - over an above the cost of the filter I would have to buy a bunch of AC plus and do not care how carefully they are made and how expensive the materials used - a screwed down connection is superior to a press-fit. I will build some AC filters and place them at the amp inputs. Each device having their own filter. Most likely the Fo-Felix filter the next time a group buy is announced.

Take care, Ric

When you use an inverter for your whole stereo system.....you are not dealing with the "house wiring" whatsoever. However, it sounds best to have all your products "grounded to the earth".....and then filter the noise on the ground wires. As mentioned his wire from his grounding rod goes to the Puritan ground filter that is also attached to the Puritan line filter.....this is where all his grounds from his equipment go and OPTIONALLY you can also attach the chassis ground on the inverter.....In this senario the chassis ground on the inverter is optional.....it is just a safety ground.....you know, in case the 120V would somehow leak to the chassis and then if you touched it you would get a shock....so, if the chassis is grounded then if 120V AC were to touch the chassis then it would short big time and all fuses would blow.....protecting you from harm.

However, if you are using plugs into the inverter (and it sounds like you are not) AND the plugs are grounded to the ground post (yet to be tested)....and you DO NOT want to use a Puritan filter or Puritan ground filter.....then using the ground post on the inverter can be used for the main ground connection point..... and that is where you would run a wire from your separate ground rod.......In any case....you're stereo is completely isolated from the house ground and the house wiring.

The Puritan filter does not have to have connectors in or out. You can simply hardwire into the Puritan....very easy....anything can be done. You could hardwire directly from the inverter into the Puritan and hardwire power cords from the Puritan directly to your gear. Lots of possibilities. It really is very simple.

but it needs checking periodically to see if there is a problem with oxidation, or needs to be prepped with a deoxit solution or dielectric grease. Even then it should be rechecked. High humidity destroys. Soldering it is the only way to ensure, but you better have a way to quickly unplug everything in case of a lightning storm. I don't trust the breaker box on/off for that.

  Either one would need periodic attention.
  
  Soldering large gauge wires is not a sure thing, either.
  
  Nothing is a sure thing, is it? Keeps us on our toes!

    I've checked mine after 15 years and all is just fine, no solder degradation, no oxidized contacts, nothing. So saying this is unnecessary. If the tension within the outlet contacts has been compromised in any way I would have just replaced it. I know enough to DIY.
    
    BTW, if anyone is reading this make sure you turn off breakers on the box before you touch anything

      I was thinking of 8 and 10 gauge Mil spec stranded wire.
      
      All less than that is another story and I would not think of doing anything other than soldering.
      
      I should have been more specific.
