Why NFPA 70B Training Matters
NFPA 70B changed from a Recommended Practice to a Standard with the 2023 edition. Its requirements are now written in mandatory “shall” language, which gives authorities having jurisdiction, insurers, auditors and facility owners a clear benchmark for evaluating electrical maintenance. The 2026 edition is now the current version, and it adds new requirements that every facility with an EMP needs to understand.
A documented, systematic Electrical Maintenance Program reduces equipment failures, unplanned downtime and arc flash risk. It also establishes the “condition of maintenance” that NFPA 70E requires when assessing electrical hazards. Equipment that is not properly maintained cannot be assumed to operate as designed during a fault.
What’s New in NFPA 70B 2026
This course covers the key changes in the 2026 edition, including:
- The potential failure to functional failure (P–F) curve method for determining maximum equipment maintenance intervals
- A new requirement to set a timeline for completing equipment repairs and corrections, so identified deficiencies are not left open
- Added detail and clarification for inspection and testing tasks in the equipment chapters
- A new chapter on transfer switch maintenance
- An operational technology (OT) cybersecurity risk assessment as a required EMP element where control systems are networked
- Expanded recognition of continuous condition monitoring, including permanently installed thermal sensors
- Stronger alignment with NFPA 70E on hazard elimination and reducing worker exposure during maintenance
What This NFPA 70B Course Covers
The course walks through the requirements of NFPA 70B in the order you apply them: establishing the EMP, assessing equipment condition, setting maintenance intervals, and performing and documenting inspections and tests on each class of equipment. It explains how to use NFPA 70B together with ANSI/NETA Maintenance Testing Specifications (MTS), manufacturer instructions, NFPA 70 (NEC) and NFPA 70E.
Participants also learn how condition-based, preventive and predictive maintenance fit into a compliant program. Topics include infrared thermography, insulation resistance testing, circuit breaker testing, dissolved gas analysis and continuous monitoring technologies.
Learning Outcomes
At the end of this course, participants will be able to:
- Explain the scope, purpose and structure of NFPA 70B 2026 and its relationship to NFPA 70 (NEC) and NFPA 70E.
- Describe what changed in the 2026 edition and what those changes mean for an existing maintenance program.
- Develop, document and implement an NFPA 70B-compliant Electrical Maintenance Program (EMP), including program responsibility, equipment inventory, documentation and auditing.
- Perform an equipment condition assessment based on physical condition, criticality and operating environment.
- Set and adjust maintenance intervals using equipment condition, the P–F curve method and manufacturer recommendations.
- Identify the inspection, cleaning and testing tasks NFPA 70B requires for major electrical equipment.
- Apply ANSI/NETA MTS test methods and interpret results to trend equipment condition and prioritize corrective action.
- Establish timelines for completing repairs and corrections in line with the 2026 requirements.
- Define qualified person requirements and integrate maintenance work with NFPA 70E electrical safety programs.
- Prepare the records, test reports and audit documentation needed to demonstrate compliance to auditors and insurers.
NFPA 70B Training – Frequently Asked Questions
What is NFPA 70B?
NFPA 70B is the Standard for Electrical Equipment Maintenance, published by the National Fire Protection Association. It sets requirements for inspecting, testing and maintaining electrical, electronic and communication systems and equipment in industrial plants, commercial and institutional buildings, and large multifamily facilities. Its goal is to prevent equipment failures and worker injuries.
Is NFPA 70B mandatory?
NFPA 70B became a Standard with the 2023 edition, so its requirements are now written in mandatory “shall” language. It is enforceable wherever a jurisdiction, insurer, facility owner or contract adopts it. It is also widely used as the benchmark for showing that electrical equipment is properly maintained.
What is new in NFPA 70B 2026?
The 2026 edition adds:
- The P–F curve method for setting maximum maintenance intervals
- A requirement to set timelines for completing repairs and corrections
- A new chapter on transfer switch maintenance
- An OT cybersecurity risk assessment as an Electrical Maintenance Program element where control systems are networked
- More detail in the equipment inspection and testing tables
What is an Electrical Maintenance Program (EMP)?
An EMP is the documented program NFPA 70B requires for managing electrical equipment maintenance. It assigns program responsibility, inventories equipment, assesses equipment condition, sets maintenance intervals, and defines inspection and testing tasks. It also covers record-keeping and periodic program audits.
How often does electrical equipment need maintenance under NFPA 70B?
NFPA 70B bases maintenance intervals on each piece of equipment’s physical condition, criticality and operating environment, rather than one fixed schedule for everything. This course shows you how to assess equipment condition and set and adjust intervals, including the P–F curve method introduced in the 2026 edition.
What is the difference between NFPA 70B and NFPA 70E?
NFPA 70E covers safe work practices for people working on or near electrical equipment. NFPA 70B covers how that equipment must be maintained. NFPA 70E relies on equipment being in a proper condition of maintenance when assessing electrical hazards, so the two standards work together.
Does OSHA require NFPA 70B?
OSHA has not adopted NFPA 70B as an OSHA standard. However, OSHA requires employers to protect workers from recognized hazards. Consensus standards such as NFPA 70B and NFPA 70E are commonly used to show what a recognized maintenance practice is.
Is there an NFPA 70B certification?
This course awards an NFPA 70B Training Certificate of completion and 1.2 CEUs (12 professional development hours). You can use these to document training for your Electrical Maintenance Program.
Who should take NFPA 70B training?
Anyone who plans, performs or manages electrical equipment maintenance, including:
- Facility and maintenance managers
- Electrical and reliability engineers
- Maintenance electricians and testing technicians
- EHS managers
- Data center and critical facility staff
- Electrical contractors
- Risk and insurance professionals
