CONTROL WIRING QUESTIONS AND
ANSWERS RATED A+
What is the primary function of electrical control wiring?
✔✔The primary function of electrical control wiring is to transmit signals that control devices
and systems, ensuring proper operation and automation.
How do control circuits differ from power circuits?
✔✔Control circuits manage the operation of devices, while power circuits deliver the electricity
needed to run those devices.
What role do relays play in electrical control wiring?
✔✔Relays act as switches that can control high-power circuits using low-power signals,
allowing for safer and more efficient control.
Why is it important to use color-coded wires in control wiring?
✔✔Color-coded wires help identify function and purpose, reducing the risk of mistakes during
installation and maintenance.

, What does a contactor do in an electrical control system?
✔✔A contactor is an electrically controlled switch that manages the flow of electrical power to a
load, such as motors or lighting.
What is a control panel, and why is it crucial?
✔✔A control panel houses the components needed to manage electrical systems, providing a
centralized location for monitoring and control.
How can you ensure safety when working with electrical control wiring?
✔✔Always turn off the power at the circuit breaker, use insulated tools, and wear personal
protective equipment to minimize electrical hazards.
What does it mean if a circuit is described as “normally open”?
✔✔A normally open circuit means that the switch remains off until activated, allowing current to
flow only when the switch is closed.
Why is grounding important in electrical control systems?
✔✔Grounding protects both equipment and personnel from electrical faults by providing a safe
path for excess current to flow away.
