Control circuits can be connected directly to the line leads (as shown in the diagram), or can be isolated from the power circuit with a transformer. Lower voltages, such as 120 or 240 V, are used if ...

You will encounter two types of ladder diagrams: the 2-wire control circuit and the 3-wire control circuit. The 2-wire control circuit is shown in Fig. 2. This circuit is used to start a motor for ...

See “Standard Motor Control Circuit Primer” in the June issue of EC&M on page 18 for a more thorough discussion of the types of reduced voltage starters. Reversing starters are designed to reverse ...
