    I need to control a 240volt 15amp circuit and a 120V 20 amp circuit with one switch. I plan to get a 20amp (definite purpose?? ) 2 pole 120volt coil normallyl open circuit. The ABB product has 450ohm coil resistance, so I calculated about .3amp for the coil. I will run the 120volt circuit...

    This hottub has a 240V 4 wire 15amp circuit, and a 120volt 20amp circuit. The wiring had been installed all directly on the floor in a spot where water was dripping on it. It also had improper circuit breakers that would have only knocked out one of the phases of the 240V. We put the wires in...

Pole contactors with a double pole, everything seems to test fine but the fan and compressor don't come on. When we manually override the contactor it...

    I have a 240v50amp circuit (2h/g) and I want to control the line current to the outlet via a timer. Simple enough to do with a contactor and a 120v timer. The complicated part is that I actually want to control the line current to two different outlets and if I could design my own contactor...

    I have a heat pump that I am having a significant issue with. When it is very hot outside (~85 Deg F or above), the unit runs fine and cools well. However, when it cools off slightly, the A/C will not run even though the stat is still calling for cooling. What happens when it is cooler is...

    I need help converting from the Ge 97f9898 to the AmRad Turbo 200. There are 6 wires coming off the ge and the AmRad schematic says and shows there should be 4 wires coming off of it (the Turbo 200) not 6. Not sure what to do here. Any help would be appreciated.
