140. If the motor shown in the illustration will not start when the «off-run» switch is placed in the run position, which of the listed components should be checked FIRST
A tripped overload relay interrupts the control circuit and is the initial step when a motor fails to start. The overload relay's normally closed contacts prevent contactor energization; therefore, checking for a tripped condition and resetting the relay is the logical first action.
