Which document provides guidelines for frequency of maintenance and electrical preventive maintenance programs?

The document that provides guidelines for the frequency of maintenance and electrical preventive maintenance programs is NFPA 70B: Recommended Practice for Electrical Equipment Maintenance. This document offers comprehensive recommendations for the maintenance of electrical equipment. It addresses various aspects, including routine inspections, preventive maintenance schedules, testing, and maintenance practices for electrical systems. By following the guidelines in NFPA 70B, organizations can ensure operational reliability, safety, and compliance with relevant safety standards.

While other documents such as NEMA Standards, IEEE Guidelines, and OSHA Electrical Safety Standards contain valuable information relevant to electrical safety and maintenance, they serve different purposes. NEMA Standards primarily focus on equipment specifications and performance criteria. IEEE Guidelines offer technical standards and best practices related to electrical engineering and technology. OSHA Electrical Safety Standards emphasize safety regulations to ensure safe practices in the workplace but do not specifically outline maintenance frequency or preventive maintenance programs like NFPA 70B does.
