Electrical Level 3 Motor Controls Exam
2025 Edition. Questions & Correct
Answers. Graded A
Describe retroreflective scan - ANS The target to be detected passes
between the sensor and reflector, interrupting the light beam
Dropout voltage - ANS Coil voltage that is reached when the armature
return spring overpowers the magnetic field of the coil and the contacts of
the device change position
If the heater in an IEC bimetallic overload relay fails - ANSYou must replace
the heater and relay (all)
Installations of start/stop buttons in multiple locations - ANSNo matter how
many stations the start pushbuttons must all be connected in parallel and
all stop buttons in series.
Jogging is also referred as - ANSinching
Most transient suppression modules consist of an RC circuit that is
designed to suppress coil voltage transients to approximately what % of
peak supply voltage? - ANS200%
NEC Article 430part VII - ANSUsed to start and stop motors. ??
