Wiring a capacitor to start a motor begins with the connection of the positive terminal of the motor to the resistor. Take one terminal of the resistor, and connect it to the capacitor. Read the wiring diagram on your appliance to understand the colors that the manufacturer designed for the three connections, namely, start, run and common. Locate the negative terminal of the capacitor, and attach it to a switch.Know More
The start connection commands a series of connections up to its winding. If the motor has a switch on the rotor with a pair of connections that are closed when the motor is not running, take one wire and put it on the start cap, and then connect the cap to that contact. Open and close the switch repeatedly to see if it works.
Ensure that the negative terminal is attached correctly to a switch before attempting a trial. In some capacitors, the black wire is connected to neutral while the brown wire is connected to the active, leaving the blue wire to go to one part of the run cap. The other part of the cap goes to the active and brown wire. Run the connection for a short time with one hand on the power switch and watch for smoke.Learn more about Electrical
A linear resistor is a resistor whose resistance does not change with the variation of current flowing through it. In other words, the current is always directly proportional to the voltage applied across it.Full Answer >
A fixed resistor is an electrical component with a fixed resistance that can not be changed. Resistors are used to reduce current and voltage in an electrical circuit. Common resistors feature a series of color-coded stripes to indicate resistance and tolerance.Full Answer >
Capacitors are available at Sears.com, Grainger.com and BestBuy.com, as of 2015. Sears and Grainger inventories include hundreds of components including motor start, motor run and aluminum electrolytic capacitors; Best Buy's offerings include hybrid capacitors. The websites offer customers an equipment comparison feature.Full Answer >
The black wire is used in all electric circuits and is always the "hot" or live wire. It usually runs from the switch to the electrical load.Full Answer >
