                            NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q68-Q73):

                            NEW QUESTION # 68
                            Which instrument is used tolocate a fault in a 15 kV underground cable?

                            Answer: B

                            Explanation:
                            Atime-domain reflectometer (TDR)locates faults by measuring reflected signals caused by impedance discontinuities. NETA Level 2 technicians must recognize proper tools for underground cable diagnostics.


                            NEW QUESTION # 69
                            When reinstalling a draw-out circuit breaker into a metal-clad switchgear cubicle, in what condition must the breaker be?

                            Answer: A

                            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 # 70
                            When personnel are working in apermitted confined space, how many attendants must remain outside the space and for how long?

                            Answer: B

                            Explanation:
                            Confined space safety requirements mandate thatat least one trained attendantremain outside the spacefor the entire duration of the entry operation. The attendant monitors conditions, maintains communication, and initiates rescue procedures if needed. NETA Level 2 technicians must comply with confined space protocols when testing transformers, vaults, or enclosed switchgear compartments.


                            NEW QUESTION # 71
                            Class 00 rubber insulating gloves are proof-tested at2,500 VAC. What color label would you expect to find on these gloves?

                            Answer: D

                            Explanation:
                            Rubber insulating gloves are color-coded to indicate their voltage class and test rating.Class 00 gloves, rated for low-voltage work, are proof-tested at2,500 VACand are identified by awhite label.
                            NETA Level 2 technicians must verify glove class, test date, and physical condition before use. Using gloves of the incorrect class or expired test date creates a serious safety risk. Color identification allows quick visual verification in the field, supporting compliance with electrical safety requirements.


                            NEW QUESTION # 72
                            A ground conductor is routed through azero-sequence current transformer (CT)together with the phase conductors feeding the load. What is the most likely result?

                            Answer: A

                            Explanation:
                            Zero-sequence (residual) ground-fault detection works by measuring thevector sum of currentspassing through a CT window. Under normal conditions, the three phase currents sum to approximately zero. If a ground fault occurs, the return current path bypasses the CT window, producing a net residual current that the CT detects.
                            If theequipment grounding conductor(or neutral/ground return conductor, depending on the scheme) is incorrectly passed through the same CT window along with the phase conductors, the ground-fault return current can be "captured" by the CT. This causes the residual sum to approachzero, even during an actual ground fault-meaning the protective function mayfail to operate.
                            NETA Level 2 technicians are expected to recognize correct CT installation practices, especially during commissioning and acceptance testing of ground-fault protection schemes. This includes verifying CT polarity, conductor routing, window CT content, and proper secondary wiring before performing injection or functional trip tests. Misrouting conductors is a classic cause of non-operational ground-fault protection.
