Question 1

A technical manual states: 'Before energizing any circuit, the technician must verify that all grounding conductors are properly connected and that no personnel are within the restricted zone.' What is the PRIMARY purpose of this instruction?

Accepted Answer

To ensure safety before applying power

Answer

The instruction lists two safety preconditions (grounding and personnel clearance) that must be met before energizing, making worker safety the primary purpose.

Question 2

A passage reads: 'The National Electrical Code requires that all electrical installations be inspected and approved by the authority having jurisdiction prior to being placed in service.' Which term describes 'the authority having jurisdiction'?

Accepted Answer

The organization or official responsible for enforcing code

Answer

'Authority having jurisdiction' (AHJ) is a standard NEC term referring to the organization, office, or individual responsible for enforcing the requirements of a code.

Question 3

Read this excerpt: 'Conductors shall be protected from physical damage. Where subject to physical damage, conductors shall be protected by conduit, electrical metallic tubing, Schedule 80 PVC, or equivalent.' The word 'equivalent' most likely means:

Accepted Answer

Another protection method offering comparable protection

Answer

'Equivalent' here means another method that provides a comparable level of physical protection to the listed options.

Question 4

A work order reads: 'Install a 20-ampere, 120-volt, GFCI-protected receptacle in the bathroom. Ensure the receptacle is tamper-resistant and located within 36 inches of the basin.' What does 'tamper-resistant' most likely refer to?

Accepted Answer

A receptacle with internal shutters that block foreign objects

Answer

Tamper-resistant receptacles have internal shutters that prevent children from inserting objects into the slots unless equal pressure is applied to both slots simultaneously.

Question 5

A safety bulletin states: 'Lockout/Tagout procedures must be followed when performing maintenance on electrical equipment. A lockout device physically prevents the energy source from being re-energized, while a tagout device only provides a warning.' Based on this, which provides MORE protection?

Accepted Answer

Lockout, because it physically prevents re-energization

Answer

The passage explicitly states that a lockout device physically prevents re-energization, making it more protective than a tagout device which only provides a warning.
