What protective measure is addressed under NFPA 70B?

NFPA 70B focuses on the maintenance of electrical equipment, outlining best practices and standards to ensure the safety and reliability of electrical systems. This includes recommendations for regular inspections, testing, and maintenance protocols to prevent failures and extend the lifespan of equipment. By following these guidelines, individuals and organizations can reduce the risk of electrical hazards and ensure that equipment operates effectively.

The other options pertain to different aspects of electrical safety and standards. Safety standards for low-voltage equipment are generally covered under a different section of the NFPA standards, which focuses on specific requirements for systems operating at lower voltages. Guidelines for installing renewable energy systems are addressed in NFPA 70, which focuses on wiring and installation practices. The installation of conductors is also covered under NFPA 70, which provides criteria for safely installing and managing electrical conductors in various systems.
