    Howdy all,
    I am trying to wire an 120volt 20 amp electric motor to a timer and the timer will be 0-60 seconds ( when I find the right one ! panel mount hopefully) I need to be able to hit an momentary on switch and get the motor running for 0-60 seconds and have the motor turn off at the end of the preset time. and the timer reset for the next activation. I would like this to all be a 120 volt circuit. any and all help is greatly appreciated!
    R.K.

    Googling 'time delay relay' brings up lots of hits.

    20A? You'll either have to find a timed relay that's capable of switching 20A or any other timed relay and a contactor.

    I assume this is a 1ph induction motor? If so that is fairly large for 1ph 120v (3HP).
    I would suggest that you use a Special Purpose contactor as these are meant for high cycle times, HVAC systems etc.
    Apart from that a timer and momentary P.B.
