NETA Safety Standards & Regulatory Compliance 3

Question 1

NETA's ANSI/NETA MTS requires maintenance testing frequency based primarily on what factor?

Accepted Answer

Equipment condition, environment, and criticality

Answer

ANSI/NETA MTS bases maintenance intervals on a condition-based approach considering equipment condition, operating environment, and criticality to operations.

Question 2

According to NFPA 70E, before an electrical worker can work within the restricted approach boundary of energized conductors, what must be completed?

Accepted Answer

An energized electrical work permit must be issued and approved

Answer

NFPA 70E requires an energized electrical work permit (EEWP) to be issued and approved before work within the restricted approach boundary of energized parts.

Question 3

Under IEEE Standard 80, the tolerable touch voltage for a person weighing 50 kg for a fault duration of 0.5 seconds is approximately:

Accepted Answer

116 volts

Answer

IEEE Std 80 defines tolerable touch voltage as approximately 116 volts for a 50 kg person at a 0.5-second fault clearing time.

Question 4

Which document type must NETA-certified technicians produce to demonstrate compliance with ANSI/NETA testing standards?

Accepted Answer

Standardized test report forms documenting all required tests and results

Answer

NETA standards require detailed written test reports using standardized forms that document all required tests, equipment data, and results.

Question 5

When NETA standards specify a 'trip test' for a circuit breaker, what is the primary safety concern being verified?

Accepted Answer

Breaker will open within manufacturer-specified time under overcurrent conditions

Answer

Trip testing verifies that the circuit breaker will open within the manufacturer's specified time-current curves under overcurrent fault conditions.
