After reading the thread "230 V from 3 phase , I notice we have some very bright elect engineers. ( I to have a degree in engineering from the school of hard knocks. In fact I have a PHD. piled higher and deeper).
Now for my question. I have only 2 hot wires buried to a 220V submersible pump in my field. I like to replace the pump to a 120V pump which I have. Can I hook one line and push a rod in the ground for a netural to get 120V? Also push another rod in the ground for a ground wire? I'll have 120V but will I kill my self ? I did not make the installation, if I did it would have been 3 wires and a ground.
Second question on another project. I built a drive way between the breaker box and my welder. Therefore, I layed underground plactic pipe about 20 ft. to run no. 6 Romax to my welders 50amp plug. I was a happy man until I read "Pocket Ref" by Thomas J. Glover on page 116 under electrical in big bold letters" NEVER PUT ROMAX OR BX INSIDE CONDUIT" My question is why?
