For decades, NFPA 70B was a recommended practice — a detailed guide that told facilities what they should do to maintain their electrical systems safely. Compliance was voluntary, and many facilities treated it as aspirational guidance rather than a binding obligation. That changed with the 2023 edition. NFPA 70B is now a mandatory standard. If your facility has not updated its electrical maintenance program accordingly, you are behind — and potentially exposed.
What Changed in the 2023 Edition of NFPA 70B?
The National Fire Protection Association restructured NFPA 70B from a recommended practice to a full standard. The language throughout shifted from ‘should’ to ‘shall’ — the critical distinction in NFPA terminology between guidance and requirement. This means the inspection intervals, testing procedures, and documentation requirements that were previously advisory are now mandated.
The scope remains the same: the standard covers the inspection, testing, and maintenance of electrical systems and equipment to reduce the risk of electrical failures, fires, and arc flash incidents. But the obligation to comply is no longer discretionary.
Why This Matters for OSHA Compliance
OSHA frequently cites NFPA standards as the basis for enforcement actions under the General Duty Clause. With 70B now a mandatory standard, OSHA inspectors have clearer grounds to issue citations for facilities whose electrical maintenance programs do not meet its requirements. The question is no longer whether you follow the best practice — it is whether you are compliant with the standard.
Key Requirements Facilities Must Now Meet
- Documented inspection and testing intervals for all electrical equipment
- Qualified personnel conducting all maintenance activities
- Written electrical maintenance program that is reviewed and updated regularly
- Records of all inspections, tests, and corrective actions taken
- Infrared thermography and predictive maintenance integrated into the program
- Equipment-specific maintenance procedures aligned with manufacturer requirements
What to Do Now
Start by auditing your current electrical maintenance documentation against the 2023 NFPA 70B requirements. Identify gaps in testing intervals, record-keeping, and personnel qualifications. Then build a corrective action plan with defined timelines. If your maintenance program is informal or undocumented, this is the year to formalize it — before an incident or inspection forces the issue.
Bowtie Engineering helps facilities build 70B-compliant electrical maintenance programs from the ground up, including NETA testing, documentation, and ongoing maintenance contracts.

Frequently Asked Questions
When did NFPA 70B become a mandatory standard?
NFPA 70B became a mandatory standard with its 2023 edition. Prior to this, it was a recommended practice — meaning compliance was voluntary. The 2023 edition restructured the document so that its requirements are now binding obligations rather than advisory guidance.
What is the difference between NFPA 70B as a recommended practice versus a mandatory standard?
The critical difference is in the language used throughout the document. The previous recommended practice used the word “should,” indicating guidance. The 2023 mandatory standard uses “shall” — the NFPA terminology for a binding requirement. Inspection intervals, testing procedures, and documentation requirements that were previously aspirational are now mandated.
How does NFPA 70B becoming mandatory affect OSHA enforcement?
OSHA frequently uses NFPA standards as the basis for enforcement actions under the General Duty Clause. With NFPA 70B now a mandatory standard, OSHA inspectors have clearer and stronger grounds to issue citations against facilities whose electrical maintenance programs do not meet its requirements. The compliance question has shifted from whether a facility follows best practice to whether it meets the standard.
What are the key requirements facilities must meet under the 2023 NFPA 70B standard?
Facilities must maintain a written electrical maintenance program that is regularly reviewed and updated, documented inspection and testing intervals for all electrical equipment, records of all inspections, tests, and corrective actions, qualified personnel conducting all maintenance activities, infrared thermography and predictive maintenance integrated into the program, and equipment-specific maintenance procedures aligned with manufacturer requirements.
What should a facility do first to achieve NFPA 70B compliance?
The starting point is an audit of your current electrical maintenance documentation against the 2023 NFPA 70B requirements. This means reviewing testing intervals, record-keeping practices, personnel qualification documentation, and whether a formal written maintenance program exists at all. Identified gaps should then be addressed through a corrective action plan with defined timelines before an inspection or incident forces the issue.
Does NFPA 70B apply to all commercial and industrial facilities?
NFPA 70B applies to facilities with significant electrical infrastructure — covering the inspection, testing, and maintenance of electrical systems and equipment to reduce the risk of electrical failures, fires, and arc flash incidents. Any facility operating electrical distribution equipment, switchgear, transformers, motor control centres, or similar infrastructure falls within its scope.
What are the consequences of not complying with NFPA 70B?
Non-compliance exposes facilities to OSHA citations under the General Duty Clause, increased liability in the event of an electrical incident or fire, and the operational risks that come with an inadequate maintenance program — including unplanned equipment failures, arc flash incidents, and electrical fires. With the standard now mandatory, the documentation gaps that were previously overlooked carry direct regulatory consequences.
How is infrared thermography specifically addressed in the 2023 NFPA 70B standard?
The 2023 edition explicitly integrates infrared thermography as a required predictive maintenance tool rather than an optional diagnostic service. Facilities must include thermography in their maintenance program for electrical distribution equipment, making it a compliance requirement rather than a discretionary investment.
