SACA C-202 ELECTRIC MOTOR
CONTROL SYSTEMS 2026 QUESTIONS
AND ANSWERS | A+ GRADED | WITH
EXPERT SOLUTIONS
Grounding - correct answer-To provide a low-resistance path for
fault current, ensuring safety and protecting equipment.
Common standards associated with electrical control - correct
answer-NEMA, IEC, and NEC standards.
Ten basic rules of electrical safety - correct answer-Includes de-
energizing circuits, using PPE, verifying lockout/tagout, testing
before touch, and using insulated tools, among others.
Lockout/tagout system order - correct answer-Notify, shut down,
isolate energy, apply LOTO device, release stored energy, and
verify zero energy.

Three-phase power operation - correct answer-Three AC voltages
120° out of phase provide continuous power with higher
efficiency.
Function of neutral in electrical power - correct answer-Serves as
a return path for current in unbalanced systems and maintains
voltage stability.
Using a digital multimeter - correct answer-Set the function (volts,
ohms, etc.), connect leads properly, and read measurements.
Grounded and ungrounded systems - correct answer-Grounded
systems have one conductor connected to ground for safety;
ungrounded systems do not, which can delay fault detection.
Overcurrent protection devices - correct answer-Fuses melt under
excess current; breakers trip; overloads respond to sustained
heat or current.
Three-phase motor operation - correct answer-Uses rotating
magnetic fields from three-phase power to turn the rotor.
