NEW QUESTION # 18
Which document should be consultedfirstbefore performing any circuit breaker testing or maintenance?
Answer: B
Explanation:
NETA standards require technicians to followmanufacturer's instructionsfirst, as they define specific procedures, tolerances, and limitations for the equipment. NETA standards supplement-not replace- manufacturer requirements.
NEW QUESTION # 19
When making a resistance measurement, which ohmmeter range should be selectedinitially?
Answer: C
Explanation:
Starting with thelowest resistance rangeprovides maximum sensitivity and allows the technician to determine whether resistance is within the expected low-ohmic range. This approach supports accurate measurements during continuity testing, bolted-connection checks, and component verification.
NEW QUESTION # 20
How many connection points are typically found on a Kelvin bridge used for low-resistance measurements?
Answer: B
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 # 21
Medium-voltage cable, as defined by NEC Article 328, is rated atwhat minimum voltage?
Answer: D
Explanation:
NEC Article 328 defines medium-voltage cable as cable rated1001 volts or higher, up to 35 kV. This distinction affects installation rules, testing requirements, and safety procedures. NETA Level 2 technicians must correctly classify cable systems to apply appropriate test methods and voltages.
NEW QUESTION # 22
A 3-phase, 480 V system supplies a balanced load drawing50 A line currentat a0.85 lagging power factor.
What is thetotal real powerdelivered to the load?
Answer: C
Explanation:
Real power in a three-phase system is calculated using:
P = #3 × V_L × I_L × PF
P = 1.732 × 480 × 50 × 0.85
P #35,300 W (35.3 kW)
NETA Level 2 technicians must be able to correctly apply three-phase power equations during load verification, commissioning, and troubleshooting. Errors in power calculations can lead to incorrect conclusions regarding transformer loading, feeder capacity, and protective device coordination.
