3 Reset and Test uttons Device Test (electronic functions) Contact Test Looping ption for with windows In applications involving the use of or G wire, usually motors of HP or less, the wires maybe looped and passed through the windows repeatedly before connecting to the contactor. y looping the motor leads through the windows in the overload a second time, the overload will read twice the current actually going to the motor. Hence the overload can protect a motor needing half the FL capability of the overload. n overload with a currentof0to0 amperes can be used for a motor FL between to 0 amperes. Similarly, motors that require only one-third, one-fourth, or one-fifth the overload s FL capability can use the same size starter by looping three, four, or five times. The following table demonstrates how the looping process reduces the current setting of the overload by the number of times the wires pass through the windows of the overload.
