So I had been planning all along to use the 240v outlet at my dryer to power my electric setup. Two 5500w 240v elements controlled by a PWM. The PWM wants a 12vdc input so it can send a signal to the SSR.
Well... I pulled the 4-prong dryer outlet apart today and realize that it had 10/2 wire run to it, so there is only hot, hot and ground. Besides wondering what is going on with the fourth prong on my dryer, since it is obviously going nowhere, i now have no power source for my PWM circuit.
My question then is, do i have to run 10/3 so i can run this circuit (it is powered by a 115v walwart) or is there some mystical way of doing it with a 10/2 240v feed? Or possible alternative that doesn't cost $100 (10/3 = expensive).
Thanks
