In an H-O-A control of a 3-phase AC induction motor using an across-the-line motor -starter, both circuits — hand and automatic — are wired as a 2-wire control of the single motor -starter even though three wires are extended to the switching location.

The three positions of the switch provide a means of interlock between the two circuits, such that the motor is either off, controlled by manual override, or controlled by a pilot device.

Both circuits, however, cannot be energized simultaneously.

A) True
