NEW QUESTION # 92
A control contact that includes one normally open (NO) contact and one normally closed (NC) contact operated by a single actuator is classified as which contact form?
Answer: D
Explanation:
Control contacts are categorized by their functional behavior and internal configuration. AForm C contact consists ofone normally open (NO) and one normally closed (NC) contactthat share a common movable contact and operate together. When the actuator changes state, one contact opens while the other closes.
This configuration is commonly used in control circuits where a change of state must simultaneously initiate one function and terminate another, such as interlocking schemes, status indication, and control logic. NETA Level 2 technicians frequently encounter Form C contacts in relays, auxiliary switches on circuit breakers, and motor control equipment.
Form A contacts are normally open only, while Form B contacts are normally closed only. Form C provides greater flexibility and is widely used in protection and control systems. Correct identification of contact forms is critical during continuity testing, functional verification, and troubleshooting of control circuits.
NEW QUESTION # 93
What is meant by adead-tank circuit breaker?
Answer: B
Explanation:
Adead-tank circuit breakeris designed so that the interrupter assembly and associated operating components are contained within ametal tank that is bonded to ground potential. Because the enclosure is grounded ("dead"), the tank is not energized during normal operation. This construction reduces touch potential hazards and provides a robust, grounded barrier around interrupting components.
This contrasts with alive-tank breaker, where the external housing or tank is atline potential, requiring greater external clearances and insulation coordination. From a testing perspective, NETA Level 2 work commonly includes verifying breaker integrity through insulation resistance, contact resistance, functional checks, and in some applications, power factor testing or vacuum bottle integrity testing (depending on breaker type). Understanding "dead-tank" vs "live-tank" is important because it influences safe work practices, test lead placement, and interpretation of results (particularly for insulation-related tests and grounding considerations).
NETA objectives emphasize technicians being able to identify equipment construction types and apply the appropriate test approach and safety controls, especially regarding grounded enclosures, bonding, and the management of induced or stored energy.
NEW QUESTION # 94
In ANSI/IEEE device numbering, which device best corresponds toDevice 52?
Answer: D
Explanation:
ANSI/IEEE device numbers provide a standardized way to identify protective and control functions in power systems.Device 52designates anAC circuit breaker. It is one of the most commonly referenced device numbers on one-lines, schematics, relay settings sheets, and commissioning documentation.
NETA Level 2 technicians must be comfortable identifying device numbers because testing tasks frequently reference them. For example, when verifying breaker control circuits, interlocks, trip/close coil operation, auxiliary contacts, or anti-pump circuits, drawings may refer to "52a" and "52b" auxiliary contacts (breaker position contacts). Similarly, protection schemes may call for verifying that a relay output properly operates the52 trip circuit.
Correct identification reduces errors during functional testing, secondary injection, and commissioning checks. Misinterpreting device numbers can lead to wiring mistakes, incorrect test points, or a failure to validate protective functions. Therefore, recognizing device 52 as the AC breaker is a core competency within Level 2 electrical testing fundamentals and component testing.
NEW QUESTION # 95
Which trigonometric function is equal to theopposite side divided by the hypotenuseof a right triangle?
Answer: A
Explanation:
Thesineof an angle is defined as the ratio of the opposite side to the hypotenuse. Trigonometry is used in power factor analysis, phasor relationships, impedance calculations, and AC circuit analysis. NETA Level 2 technicians must understand these relationships when evaluating voltage, current, and phase angles in testing scenarios.
NEW QUESTION # 96
When personnel are working in apermitted confined space, how many attendants must remain outside the space and for how long?
Answer: D
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.
