    Is your switch rated for motor starting? On start up motors can draw a lot of current, a lot more than their nameplate rating. That is why sometimes lights dim when motors come on. One way around it is to run your motors at higher voltage if you can wire them that way. Double the voltage is half the amperage for the same power.

    I just put up an article about a motor starter circuit I made on this site. I was worried the contacts I used weren't going to do the job but so far so good. I used a 30 amp contactor on a 7 amp motor. But on start up that motor could draw 40 or more amps.
