SECTION ONE: QUESTIONS 1 – 50
════════════════════════════════════
1. What is the primary purpose of the insulation on a pair of combination pliers used by an electrical craft helper?
A. To provide a comfortable grip for prolonged use
B. To protect the tool from rust and corrosion
C. To prevent electrical shock when working on live circuits
D. To allow for easier identification of the tool
🟢 Correct Answer: C. To prevent electrical shock when working on live circuits
🔴 Explanation: Insulated tools are specifically designed and rated to protect the user from electrical shock. The
insulation acts as a barrier between the user and the conductive metal of the tool.
2. When inspecting a fiberglass extension ladder for use, what is the most critical defect to look for?
,A. Faded paint on the rails
B. Cracks, splinters, or crazing in the fiberglass
C. Worn rubber feet
D. Loose rivets on the spreader bars
🟢 Correct Answer: B. Cracks, splinters, or crazing in the fiberglass
🔴 Explanation: Cracks or crazing in fiberglass can lead to catastrophic structural failure. While other options are
concerns, compromised structural integrity is the most critical safety issue.
3. A lever is used to pry a heavy cover from a manhole. The fulcrum is placed close to the load. This arrangement
provides:
A. Increased speed of movement
B. A mechanical disadvantage
C. A mechanical advantage
D. The same force as without the lever
🟢 Correct Answer: C. A mechanical advantage
🔴 Explanation: A lever with the fulcrum placed close to the load provides a large mechanical advantage, allowing a
smaller input force to move a larger load.
, 4. What is the standard sling angle factor for a vertical hitched sling?
A. 1.0
B. 0.866
C. 1.414
D. 2.0
🟢 Correct Answer: A. 1.0
🔴 Explanation: A vertical sling has a 90-degree angle to the load, and the stress on the sling is equal to the weight
of the load. Therefore, the angle factor is 1.0.
5. An electric motor nameplate indicates it is rated for 240 volts and draws 10 amps. What is the approximate
power consumption of this motor?
A. 1200 watts
B. 2400 watts
C. 4800 watts
D. 7200 watts
🟢 Correct Answer: B. 2400 watts
🔴 Explanation: Power (Watts) is calculated by multiplying Voltage (Volts) by Current (Amps). 240V * 10A = 2400W.
