SACA C-202 Electric Motor Control Systems ACTUAL
EXAM (2025) 100%VERIFIED | QUESTIONS AND
ANSWERS | GRADED A+.
Grounding - (ANSWER)To provide a low-resistance path for fault current,
ensuring safety and protecting equipment.
Common standards associated with electrical control - (ANSWER)NEMA, IEC, and
NEC standards.
Ten basic rules of electrical safety - (ANSWER)Includes de-energizing circuits,
using PPE, verifying lockout/tagout, testing before touch, and using insulated
tools, among others.
Lockout/tagout system order - (ANSWER)Notify, shut down, isolate energy, apply
LOTO device, release stored energy, and verify zero energy.
Three-phase power operation - (ANSWER)Three AC voltages 120° out of phase
provide continuous power with higher efficiency.
Function of neutral in electrical power - (ANSWER)Serves as a return path for
current in unbalanced systems and maintains voltage stability.
Using a digital multimeter - (ANSWER)Set the function (volts, ohms, etc.), connect
leads properly, and read measurements.
, Grounded and ungrounded systems - (ANSWER)Grounded systems have one
conductor connected to ground for safety; ungrounded systems do not, which can
delay fault detection.
Overcurrent protection devices - (ANSWER)Fuses melt under excess current;
breakers trip; overloads respond to sustained heat or current.
Three-phase motor operation - (ANSWER)Uses rotating magnetic fields from
three-phase power to turn the rotor.
Interpreting motor's nameplate data - (ANSWER)Includes voltage, current, RPM,
phase, service factor, and efficiency.
Connecting dual-voltage three-phase motor - (ANSWER)Use parallel connection
for low voltage (e.g., 230V) and series for high voltage (e.g., 460V).
Functions of motor control - (ANSWER)Starting, stopping, reversing, speed
control, and overload protection.
Motor control relay circuit interpretation - (ANSWER)Understand how control
relays activate coils and change contact states to control the motor.
Operation of different types of motor starters - (ANSWER)Manual, magnetic, and
solid-state starters vary by control type and application.
