There can NOT be a grounding wire or rod outside, it is impossible. If there were, since the neutrals and grounds are both bonded together in the panel box and therefore leave the panel box bonded together there could be no way to ever separated those paths on the outside? Impossible.There may be a grounding wire and grounding rod (or tied into rebar when foundation was laid) at the meter outside. That was my point. The large aluminum conductor is the common Neutral conductor
Well I never knew this site to be highly censored but I guess that is just the way things go now a days.It seems, at this point, that on-line advice can not help answer questions that a qualified electrician should answer on-site. The concerns here should be addressed with a licensed electrician.
Whats up? EMFs harm everyBODY. I am maybe more sensitive than you are. I am willing to do something to reduce the harm. That is why I have no smartphone, no microwave, no wifi, etc. Who do you think would spend money for an emf filter but one who knew they were being harmed by them?So the question brewing in my head:
1HW...no microwave, no smartphone, EMF filter.......What's up??
The neutral doesn't go back any farther than the center tap of the transformer and grounding is just for safety. Nothing in the house requires a ground to operate except for ground fault devices. My panel with bonded neutral and ground is grounded to a copper water pipe but the neutral at the meter box outside is grounded to a ground rod. The neutral current flows to the transformer and not into the ground (unless there is a ground fault).There can NOT be a grounding wire or rod outside, it is impossible. If there were, since the neutrals and grounds are both bonded together in the panel box and therefore leave the panel box bonded together there could be no way to ever separated those paths on the outside? Impossible.
So either the neutrals and grounds are both grounded outside (I have read that many years ago all neutrals were "sent back" to the elec utility through the ground but I dont think that happens any longer (but hey what do I know.... not much) OR they both travel back on the neutral wire (grounds and neutrals).
Either way it seems very strange and "not right" but heck what do I know (not much it seems).
Ok but if they are both bonded together than they can not go to separate places.The neutral doesn't go back any farther than the center tap of the transformer and grounding is just for safety.
The emf filter people may be pulling your leg as all main panels in the US have neutrals bonded to ground if they meet code.
Here's a link that may help you;
This statement bothers me. If the emf filter people don't understand basic electricity how can they clean it? The only current that flows in branch circuit neutrals is from the devices plugged into the receptacles. If the emf filter causes current flow it is merely from the electricity it consumes as with all other devices. Electricity is not recirculated through house wiring, bonding at the panel has no effect on neutral currents. I would like to see a schematic of an emf filter, I am suspecting they are snake oil.He said they use the neutral to return the electricity after it has been "cleaned" back into the house.
Yes Afjes I agree and understand what you are saying. With your analogy one can see that if the electricity, after being "cleaned", was not returned somehow back into the house the entire 240 V would be "used up" and sent into the sewer (in your analogy).To put it simply think of the flow of electricity going thru your house like the plumbing in your house.
Current comes in from the utility pole on the hot and returns on the neutral out to the utility pole.
Compare it to water coming into your house in the water line and going back out in your sewer line.
Slownsteady, that certainly would make more sence and infact when I first read about the filter I presumed that was how it was installed (until I found out differently). BUT the company states that all devices (like HVAC) that is attached to both the A / B legs as well as any circuit on the A or on the B legs will be "cleaned". But I cannot see how that could work.The part that puzzles me is that the device is only on one circuit (branch). How does that filter electricity on the other branches? Wouldn't it need to be upstream of the main breaker?
