    Twist lock 3 prong

    Had to replace pump and motor for above ground pool. (Did it myself ) Former motor was powered with the twist lock. New Haywood 1HP does not come standard with twist, only 3-prong. Currently using a 12/3 25' extension cord to power the filter motor. (Only 10' away).

    My question is:. Should I find a way to use the twist plug? I noticed home depot sells an adapter from 3 prong to twist, is that safe and efficient? Or do I hire an electrician to do their thing and convert the 3prong to twist? Can I use the twist from previous motor?

    A gfci protected twist lock is preferred. But a 3 prong would work if you didn't have that extension cord in there. Look at the name plate data for the old and new motor as long as the old motor was drawing the same or more ammount of current you can take the twist ick from the old pump and swap it to the new one. It should be gfci protected tho there are a lot of above ground pump motors out there without gfci protection thanks to an old loophole in the NEC code that has since been closed.

    Is that something I would need to hire an electrician for?

    They are pretty easy to install but it depends on what you know about residential wiring.

    Re: Twist lock 3 prong

    My knowledge of wiring is quite limited. Until I am able to get someone to rewire the plug for me, which is the better solution? A three prong to twist adapter or running the extension cord?

    Thank you for you help.

    The twist lock adaptor would in my opinion be a better solution over running an extension cord to power a pool pump motor. So long as the voltage is the same.
