Electrical transformer hook up

The motor branch circuit is usually a segment of a larger electrical distribution network in an industrial plant. The motor circuit supplies the required power to the various control devices in order for them to operate. Sometimes, the voltage required to operate the motor is too high to safely operate the control circuit, particularly in regards to personnel safety. Note that the primary winding is connected to the power source.

Applying AC voltage to the primary winding of the transformer causes alternating current AC to flow in the winding. Note that the main motor circuit operates at V, while the control circuit is at V. The secondary winding is connected to the control circuit. This will convert the starter from Common Control to Separate Control.

The leads from the secondary of the transformer are connected to Terminal 1 of the remote pilot device, and terminal 96 on the Freedom Series overload relay see Figure 4 above. Another reason for the step down xfmr is not only safety of personnel and pilot lights, atypical motor starters are connected to an additional remote start EMS or BCMS relays. The smaller ice cube relays, typically switch the control circuit on and off at a lower voltage i. Controlled by a 24 vac control circuit.
