Many power-consuming devices such as single-phase motors are designed for dual-voltage operation. Figure 1 shows a solenoid valve with four different colored wires coming from its wire housing. Figure ...

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

Inevitably, industrial facilities are going to have 460VAC, 3-phase motor loads. And, of course, since voltage drop is considered mainly a performance issue, maximum voltage drop rules on a circuit ...
