Old generac generator. 2 - 110v receptacles and 1 - 220 volt receptacle. I
wanted to back feed though a dryer plug (house main off of course) to save
running cords all over the house and be able to run the well pump(220)
without rewiring it. I figured I could run one hot side of 220 to one side
of dryer, the other hot to the other side of dryer and the neutral to the
center of the dryer plug. I get 220v across the 2 hots and 110v between each
hot and neutral. However the results baffle me. Some of my house recept now
show over 150v and others less than 80. Is there some phase problem with
using the same neutral for all the 110 recepts?
Don't. You proposal is highly unsafe. Run the extension cords. That
will be much safer. If you need to run your pump, totally disconnect
it from the mains wiring, and connect it to the 220V receptacle on the
