NFPA 70b Training - Electrical Equipment Maintenance

NFPA 70b Training

This NFPA 70b training course is particularly useful for industrial and commercial electrical engineering and maintenance professionals, electrical maintenance supervisors, plant electricians, as well as field and plant personnel who may come in contact with electrical equipment.

Our "NFPA 70b Training course is an in-depth examination of the NFPA 70B. These recommended practices apply to preventive maintenance for electrical, electronic, and communication systems and equipment installed in industrial, commercial and institutional power systems.

This course is designed to alert electrical maintenance personnel in utility, industrial, commercial and institutional facilities to the latest North American Electrical Maintenance and Testing Specifications. These specifications cover the suggested field tests and inspections that are available to assess the suitability for continued service and reliability of electrical power distribution equipment and systems. The purpose of these specifications is to assure that tested electrical equipment and systems are operational and within applicable standards and manufacturer's tolerances and that the equipment and systems are suitable for continued service. This program will also deal with the important subject of troubleshooting electrical systems and choosing the proper preventive maintenance testing equipment and procedures.

This complete NFPA 70B Electrical Maintenance training course includes a copy of the 230-page Standard.


Upon completion of this course, the participant should be able to:

  • Learn How to design and implement a cost-effective electrical maintenance program.
  • Learn the essential procedures for the safe operation, repair, testing, and maintenance of major power equipment.
  • Students will learn how to establish what electrical maintenance work can be done in-house or contracted out.


WHO should attend

This comprehensive two-day course is designed to benefit those working in maintenance that desire to increase their practical knowledge of electrical maintenance standards and practices. The course is open to industrial, commercial and institutional electrical engineering and maintenance professionals, plant electricians, electrical maintenance supervisors, field and plant personnel.
