Because the motor control circuit is a power-limited circuit (_______________ ______________(_____________- ____________ system), the NE Code does not specifically forbid the NC overload-relay control contacts from being wired in series with the motor-starter solenoid coil on its grounded return side.
Most new 3-pole electromagnetic motor-starter solenoid are wired at the point of _______________________________________ with the NC closed contacts of the overload relay in series with the solenoid coil on its common or return side.
Instead, the NE CodeĀ® specifies the motor control circuit must be so wired or arranged that ________________________________ grounding of any control-circuit conductor will not start the motor automatically nor will itor bypass any manual shutdown devices or any automatic safety shutdown devices in the control circuit.
