    Boy I better stop now while I am behind. As I said I am not thinking straight.

    Somehow I would think my Birthday would be better but found out today that my company is dissolving and I am out of a job.

      A 240 volt motor does not need or require a grounded circuit conductor. All they require is L1, L2, and G.

        That just suks. When I was at MCI/Worldcom one of my very good friends got laid off sitting in a hospital bed a few hours after a Heart Bypass surgery.

          Sorry about the bad news but you have a good attitude - that should help you pull through.

            Happy Birthday!
            Bad luck about the job. Hope you can sort it all out soon. Good luck

              Thanks for the Birthday cheer and vote of confidence guys. I am sure I will find something to fill my time and may even get paid for it.

                First time I 'retired' for ten years (stopped punchin a time clock) I was 28 years old and been bizy ever since. There is no end of positive things to do in the world for the good of you and others.... and yes, sometimes we even get paid in $$$$ for it. Do what you love and you'll never have to feel like you're working again.

                  You need an inverter that can produce at least 6000 watts surge, to start the motor.
                  It can be 120 or 240V. If you use 120V, you need a BIG transformer to step it up to 240V and may as well have bought a 240v inverter.

                  Real Power consumed. My inverter's power readout shows that my 1/2 hp pump, consumes 1,000 watts with 160' of head. There are motor losses, power factor losses, and specs that lie.

                    Is there a way to reduce the starting surge yet get the pump primed? I figure maybe some type of "soft" start technology for water pumps. That also will reduce any water hammer a sudden flow of fluid causes.
