NETA Safety Standards & Regulatory Compliance 4

Question 1

Under NETA standards, what is the purpose of performing a dielectric withstand (hi-pot) test on electrical equipment?

Accepted Answer

To verify insulation integrity by applying voltage above normal operating levels

Answer

To measure conductor resistance under normal load

Answer

To calibrate protective relay settings

Answer

To measure the power factor of insulating materials

Question 2

According to ANSI/IEEE C2 (National Electrical Safety Code), the minimum vertical clearance for a 69 kV overhead line crossing a public road is:

Accepted Answer

28 feet

Answer

18 feet

Answer

22 feet

Answer

35 feet

Question 3

NETA's testing standards require that the calibration of test equipment be traceable to:

Accepted Answer

NIST (National Institute of Standards and Technology)

Answer

IEEE calibration databases

Answer

The equipment manufacturer's internal standards only

Answer

International Electrotechnical Commission standards only

Question 4

When working in a confined space that contains electrical hazards, which standard takes precedence along with OSHA's permit-required confined space standard (29 CFR 1910.146)?

Accepted Answer

Both NFPA 70E electrical safety requirements and OSHA 1910.146 apply simultaneously

Answer

Only NFPA 70E applies in confined spaces

Answer

OSHA 1910.146 supersedes all electrical safety standards inside confined spaces

Answer

IEEE standards replace NFPA 70E in confined space environments

Answer

Holds a valid state electrician license

Answer

Has received OSHA 10-hour training certification

Answer

Has completed a college-level electrical engineering degree

Question 6

Under OSHA 1910.303, the minimum working space depth in front of electrical panels operating at 601 to 2500 volts with exposed live parts on one side and grounded surfaces on the other is:

Accepted Answer

4 feet

Answer

2 feet 6 inches

Answer

3 feet

Answer

5 feet

Question 7

Accepted Answer

NETA Level 3 certification

Answer

NETA Level 1 certification

Answer

NETA Level 2 certification

Answer
