NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q70-Q75):

NEW QUESTION # 70
When reinstalling a draw-out circuit breaker into a metal-clad switchgear cubicle, in what condition must the breaker be?

Answer: D

Explanation:
For safety and mechanical integrity, circuit breakers must beopen and racked outbefore installation or removal from cubicles. NETA Level 2 technicians must follow correct breaker handling procedures to prevent arc flash, equipment damage, and mechanical interlock failures during commissioning and maintenance.


NEW QUESTION # 71
When may anunqualified personenter theLimited Approach Boundary?

Answer: B

Explanation:
The Limited Approach Boundary defines the minimum distance from exposed energized parts that unqualified persons arenever permitted to cross. Entry into this space is restricted to qualified persons who understand the hazards and are trained to apply proper protective measures.
NETA safety objectives emphasize that escorting, PPE, or voltage level does not override qualification requirements. Only qualified individuals with appropriate training and authorization may enter the Limited Approach Boundary. This rule is foundational to preventing shock injuries and is strictly enforced during testing, inspection, and commissioning activities.


NEW QUESTION # 72
Which voltage is recommended by NETA-ATS for a15-minute AC withstand teston a three-phase34.5 kV line sectionalizerrated for a150 kV impulse withstand voltage?

Answer: C

Explanation:
NETA-ATS specifies withstand test voltages based on equipment rating and impulse withstand capability. For a 34.5 kV line sectionalizer with a 150 kV BIL, the recommended15-minute AC withstand test voltage is 78 kVAC. NETA Level 2 technicians must apply the correct test voltage to avoid damaging insulation while still verifying dielectric integrity.


NEW QUESTION # 73
Underground service conductors between the service equipment terminals and the service lateral are referred to as:

Answer: B

Explanation:
Service point conductors connect the utility service lateral to the service equipment terminals. Understanding conductor classification is important during inspection, testing, and verification of grounding and bonding systems. NETA Level 2 technicians must correctly identify conductor types to apply appropriate testing and safety requirements.


NEW QUESTION # 74
How many connection points are typically found on a Kelvin bridge used for low-resistance measurements?

Answer: A

Explanation:
A Kelvin bridge, also known as a four-wire resistance measurement device, usesfour connection pointsto accurately measure very low resistances. These consist of twocurrent terminalsand twopotential (voltage) terminals.
This configuration eliminates the effects of lead resistance and contact resistance, which can significantly distort measurements when testing bolted connections, bus joints, and grounding conductors. NETA Level 2 technicians routinely use Kelvin methods when performing low-resistance ohmic measurements during acceptance and maintenance testing.
Using fewer than four terminals would result in inaccurate readings, especially at milliohm or micro-ohm levels. Understanding this principle ensures proper test setup and reliable data interpretation.


NEW QUESTION # 75
