If all that is true then why are the neutral and ground wire connected together at both ends.
Not supposed to be connected at both ends. The neutral is only to be bonded to earth potential at the hydro services 1st distribution panel.
At the equipment used and the main box. My nephew who has a degree in Electrical engineering and installs solar systems was up here and was rewiring my house. We both laughed about the phony ground wire that seems to do nothing but sell wire.
Send the kid back to school.
In Oregon the power companies have to run a ground between every pole and ground it to the earth. They complain a lot about the waste of wire.
They are complaining about cost between, "It works" vs. "doing it right".
I know a lot you experts have bought the ground wire thing hook line an sinker but stop and think about what it actually does. The older electrical things only had two wires and they ran very good. But if you plugged them in backwards the outside of the metal case became hot. The 3 prong plug made this imposable to do this if the house was wired correctly. PS a neutral wire is not needed on 220 equipment only on 110 because you have to use one hot and a ground to get 110.
One line and neutral, not one line and ground. Running load current through ground/earth is looking for trouble as previously explained.
If you don't believe this then take light hook up one wire to center and the other wire around the outside and push it into the ground, the light will work quite well.
Low current load. Try it with 30 amps and start touching between the ground rod and true earth.
This won't work on your car because the battery is the power source and needs to make a complete circuit back to negative post. Walt
Electrons flow from the negative post to positive post. The chassis return system on vehicles causes much confusion when somebody trys to think an AC building service the same way.
Why pray tell do we run two insulated lines, an insulated neutral and a bare ground to the stove and clothes dryer.
I can wire your entire house with porcelain fence knobs and barbed wire. Everything will "work" but is it "right".

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
