changing pool pump cord

[CarlD]

OTOH, in-ground pumps usually don't come with the cord and it has to be installed. Mine did and it DEFINITELY has the twist-lock--because it is a 220 volt pump!

If your pump is 110, and your outlet is 220, you can't do this. But, if your pump can also be wired for 220, (it's in the manual) you would do much better to replace the cord with a twist-lock assuming the outlet turns out to be 220. If you have the choice on your pump's motor, 220 runs cooler and more efficiently and your bill will be lower while your pump motor runs for more years.

But be careful: There are a number of different 220 twist-lock plugs depending on the amperage draw (and, also remember that 20amps at 110 translates to 10amps at 220. Why? Watts = Volts x Amps and that's always and forever. Double the volts and to get the same wattage you halve the amperage. Your pump will draw the same wattage no matter what because the watt is a unit of work.) So....the wattage of the twist lock determines its configuration.

And, of course, the configuration of a 110 twist-lock is different from 220s!
