The difference between 220 and 115?

105!

Thanks everyone for coming. cschmelz will be here all week with another show at 9:00pm

Go with 220V when possible. The same HP motor will require twice as much current (amps) at 110V compared to 220V. As was stated previously, you will need a significantly larger wire size at 110V for this reason.

Also, the start up current of a motor can be 6 to 12 times the amount of the running current (FLA). With 220V you are drawing less current and spreading it over the 2 halves of your electrical panel, which I believe is less likely to cause lights to dim, etc.

Unfortunately every 2 speed 220V pump moves too much water for my application. Looks like a Whisperflo 1 HP uprated 115V pump for me. Wish I could have done it but the 220V 1 HP pump moves 90 gpm (115V 70gpm) which is overkill for my 16,000 gallon pool.

Thanks,
Joe
