NETA ETT Level 4 Practice Questions - NETA ETT Level 4 Senior Certified Electrical Testing Technician Exam - NETA ETT Level 4 Practice Questions - NETA ETT Level 4 Senior Certified Electrical Testing Technician Exam

Question 1

ANSI/NETA ETT Level 4 classifies the Certified Senior Technician as:

Capable of supervising large projects and multiple crews, working independently, performing complex investigations/tests/evaluations, and preparing written reports A trainee requiring supervision A support-only role Limited to Level 1 tasks

Correct Answer:

Capable of supervising large projects and multiple crews, working independently, performing complex investigations/tests/evaluations, and preparing written reports

Question 2

IEEE 1584-2018 arc flash calculation method differs from the earlier 2002 edition primarily in:

Electrode configuration dependence (VCB, VCBB, HCB, VOA, HOA) and a model including short-, intermediate-, and long-arc regions Only unit conversion Only fault-current definition Only working distance

Correct Answer:

Electrode configuration dependence (VCB, VCBB, HCB, VOA, HOA) and a model including short-, intermediate-, and long-arc regions

Question 3

A short-circuit study input 'available utility fault MVA' at a substation bus is converted to per-unit impedance by:

Z(pu) = MVA(base) / MVA(sc) — the utility source impedance in per-unit on the study base Z(pu) = MVA(sc) / MVA(base) Z(pu) = MVA(sc) * MVA(base) Z(pu) = 1 / MVA(sc)

Correct Answer:

Z(pu) = MVA(base) / MVA(sc) — the utility source impedance in per-unit on the study base

Question 4

A coordination study for a 480 V industrial facility with a 2000 A main and 1200 A feeder breakers must show:

Selective coordination to the highest available fault current, with at least the minimum time-current curve separation per manufacturer (e.g., 200 ms between LT regions) and compliance with any code requirements (e.g., NEC 700.28/701.27 for emergency/legally required standby) Only overlapping curves Only a motor curve Only thermal damage

Correct Answer:

Question 5

An 'arc flash boundary' per IEEE 1584 is:

The distance at which the incident energy equals 1.2 cal/cm^2 — the onset of a second-degree burn The same as the shock boundary Always 10 ft The breaker nameplate rating

Correct Answer:

The distance at which the incident energy equals 1.2 cal/cm^2 — the onset of a second-degree burn
