EEI TECH EEI Tech Reading Comprehension 1 — Questions and Answers
Question 1: A safety manual states: 'All personnel must de-energize equipment before performing maintenance.' What does 'de-energize' most likely mean?
- Boost power levels
- Remove electrical power (Correct answer)
- Replace fuses
- Test voltage output
Correct answer: Remove electrical power
In an electrical context, 'de-energize' means to disconnect or remove power from the equipment.
Question 2: A procedure reads: 'Verify insulation resistance before applying voltage.' What must happen FIRST?
- Apply voltage
- Check insulation resistance (Correct answer)
- Replace the insulation
- Record voltage levels
Correct answer: Check insulation resistance
The word 'before' indicates insulation resistance must be checked prior to applying voltage.
Question 3: A report states: 'Three of five generators were operational; the remaining units underwent scheduled maintenance.' How many generators were under maintenance?
- 1
- 2 (Correct answer)
- 3
- 5
Correct answer: 2
5 total − 3 operational = 2 undergoing maintenance.
Question 4: An instruction reads: 'Tighten all connections to manufacturer specifications; over-tightening may damage terminals.' What is the risk of over-tightening?
- Loose connections
- Terminal damage (Correct answer)
- Voltage increase
- Fuse blowing
Correct answer: Terminal damage
The passage explicitly states that over-tightening may damage terminals.
Question 5: A notice reads: 'Equipment tagged 'Out of Service' must NOT be operated under any circumstances.' A technician needs to test a tagged motor. What should they do?

- Get supervisor clearance before proceeding (Correct answer)
- Ignore the tag if qualified
Correct answer: Get supervisor clearance before proceeding
The notice says 'under any circumstances,' meaning authorization/clearance is required before operating tagged equipment.
Question 6: A manual states: 'Conductors must be rated for 125% of the continuous load.' If the continuous load is 40 amps, what is the minimum conductor rating?
- 40 A
- 45 A
- 50 A (Correct answer)
- 55 A
Correct answer: 50 A
40 × 1.25 = 50 amps minimum conductor rating.
