Practice Questions And Correct Answers
(Verified Answers
1. Which of the following is the most important factor when climbing a
| | | | | | | | | | |
utility pole?
| |
A. Speed
B. Wearing comfortable clothing | |
C. Proper use of climbing equipment and PPE
| | | | | |
D. Pole height |
Rationale: Proper use of climbing equipment and personal protective
| | | | | | | |
| equipment (PPE) is essential to prevent falls and ensure safety while
| | | | | | | | | |
| working on poles.
| |
2. What is the minimum approach distance to a 7.2 kV energized line
| | | | | | | | | | |
according to OSHA standards?
| | | |
A. 1 foot
|
, B. 2 feet 4 inches
| | |
C. 3 feet |
D. 4 feet |
Rationale: OSHA specifies minimum approach distances to prevent
| | | | | | |
| accidental contact with live lines; for 7.2 kV, it is 2 feet 4 inches.
| | | | | | | | | | | | |
3. Which type of grounding is used to protect workers from accidental
| | | | | | | | | |
|energization of lines? | |
A. Equipment grounding |
B. Personal protective grounding (PPE grounding) | | | |
C. Neutral grounding |
D. System grounding |
Rationale: Personal protective grounding is applied to de-energized lines to
| | | | | | | | |
| create a safe path for fault current, protecting workers from accidental
| | | | | | | | | |
| energization.
4. What is the primary function of a transformer on a distribution line?
| | | | | | | | | | |
A. Increase current |
B. Measure voltage |
C. Change voltage levels | |
D. Provide lightning protection | |
Rationale: Transformers are used to step up or step down voltage to
| | | | | | | | | | |
| appropriate levels for distribution and end-user use.
| | | | | |
, 5. Which of the following is the primary hazard when using bucket trucks
| | | | | | | | | | |
near energized lines?
| | |
A. Falling from bucket | |
B. Overloading the bucket | |
C. Electrocution due to contact with energized conductors | | | | | |
D. Mechanical failure |
Rationale: Electrocution is the primary hazard; proper distance and
| | | | | | | |
| insulated equipment are critical.
| | |
6. When performing a line splice, which tool is essential for ensuring a
| | | | | | | | | | |
safe and reliable connection?
| | | |
A. Hammer
B. Screwdriver
C. Lineman pliers and wire connectors | | | |
D. Wrench
Rationale: Lineman pliers and appropriate connectors ensure electrical
| | | | | | |
| continuity and mechanical strength in splices.
| | | | |
7. What is the purpose of a fuse cutout on a distribution line?
| | | | | | | | | | |
A. Increase line voltage | |
B. Provide surge protection | |
C. Protect transformers and lines from overcurrent
| | | | |
D. Measure line current | |
, Rationale: Fuse cutouts automatically open when current exceeds rated
| | | | | | | |
| limits, preventing damage to equipment.
| | | |
8. What is the standard length of a lineman’s climbing belt?
| | | | | | | | |
A. 24 inches |
B. 36 inches |
C. Adjustable to fit the lineman securely | | | | |
D. 48 inches |
Rationale: Climbing belts must be adjustable to ensure a secure and safe fit
| | | | | | | | | | | |
| around the lineman’s body.
| | |
9. Which of the following is a common symptom of electric shock?
| | | | | | | | | |
A. Sweating only |
B. Muscle contractions and burns | | |
C. Dizziness only |
D. Headache
Rationale: Electric shock often causes involuntary muscle contractions,
| | | | | | |
| burns at contact points, and sometimes cardiac effects.
| | | | | | |
10. Which type of insulator is most commonly used for overhead
| | | | | | | | |
| distribution lines? |
A. Glass
B. Wood
C. Porcelain or polymer | |
D. Rubber
