How to Wire a Pressure Control Using a Moto Rand Capacitor

Pressure control, or pressure switches, are switches found on water pumps for individual home water well systems. The pressure control monitors the system's water pressure and activates the pump when pressure is needed. The pressure control is activated and run by a run capacitor, which is a motor capacitor. The Rand Moto capacitor is a brand of motor capacitor. If the pressure control on the water pump goes out, it can be replaced with a Moto Rand run capacitor.
