What changed in NFPA 70B (2023): "should" became "shall."
For decades, NFPA 70B was a recommended practice — guidance a building owner could adopt or set aside. The 2023 edition changed the document's character: it is now a standard, written in mandatory language. If you own or operate a commercial building, here is what actually changed, what did not, and what it means for the maintenance program you may or may not have on paper.

From recommended practice to standard
The most consequential change is classification. NFPA 70B, the standard for electrical equipment maintenance, was reclassified in its 2023 edition from a Recommended Practice to a Standard. In NFPA's document hierarchy that distinction is not cosmetic: a recommended practice says "should," a standard says "shall." The permissive language was replaced with mandatory language throughout the document.
On its own, NFPA 70B becomes enforceable wherever an Authority Having Jurisdiction (AHJ) adopts it by reference — and a growing list of states and municipalities are doing so. But even where no AHJ has adopted it, the reclassification matters, because OSHA and insurers use the standard as the measuring stick for an obligation that already exists in federal law. More on that below.
A written program, with named people
The 2023 edition expects a written Electrical Maintenance Program (EMP) — a documented program, not an informal practice. Two roles anchor it. The EMP Coordinator is the named person accountable for running the program: setting priorities, keeping records current, and making sure the work happens. Qualified Persons perform the maintenance itself, defined consistently with NFPA 70E as people with documented training, current certifications, and authority delegated by the coordinator.
"Named" is the operative word. "Maintenance handles it" no longer describes a program. A reviewer will ask who the coordinator is, who the qualified persons are, and where their training records live — and the answers are expected to be in the file, not in someone's head.
More prescriptive maintenance intervals
Earlier editions left much of the cadence question to judgment. The 2023 edition is more prescriptive: it provides explicit tables for time-based and condition-based maintenance intervals across equipment classes, with the assessed condition of each piece of equipment driving how often it must be serviced (Chapter 9). Equipment in worse condition earns shorter intervals; well-maintained equipment can earn longer ones.
The practical consequence: you need to know what equipment you have, what condition it is in, and when each item was last serviced. That is an inventory, a condition assessment, and dated inspection records, respectively. The cadence tables only work if those records exist.
What did not change
The physics and the work are the same. Transformers still benefit from infrared scanning, switchgear still needs cleaning and exercising, connections still loosen, and protective devices still need testing. If your facility already ran disciplined electrical maintenance, the 2023 edition mostly asks you to document what you were doing: a written program, named roles, and records that link the work to the equipment.
What changed is the consequence of not being able to show it. Under a recommended practice, thin documentation was a gap. Under a standard that OSHA, AHJs, and insurers reference, it is a liability.
Why the change has teeth
NFPA 70B is not itself federal law. The underlying obligation to maintain electrical equipment in safe condition comes from OSHA and has existed for decades. Two provisions do the work.
OSHA's General Duty Clause, Section 5(a)(1) of the OSH Act: "Each employer shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees."
29 CFR 1910.303(b)(1): "Electric equipment shall be free from recognized hazards that are likely to cause death or serious physical harm to employees."
What the 2023 edition changed is how the recognized standard for satisfying that obligation reads. OSHA inspectors increasingly use NFPA 70B as the recognized industry standard for evaluating whether maintenance is sufficient, and an employer who cannot produce a written Electrical Maintenance Program now has a much harder defense in a citation, an insurance claim dispute, or a wrongful-injury suit.
Insurers moved in the same direction. After the 2023 edition was published, several national property and equipment-breakdown carriers updated underwriting guidelines to ask risk-managed accounts for evidence of a documented EMP. Specifics vary by carrier and by renewal cycle — ask your broker; they have a stake in the answer.
Where to start
If you are starting from zero, the order of operations is consistent: catalog your equipment and produce a one-line diagram; name an EMP Coordinator and your Qualified Persons; put every asset on a maintenance interval; record inspections as they happen, with dates, names, and findings; track every finding to resolution; and keep your engineering studies on file.
None of it is exotic. All of it must be written down. The change in NFPA 70B (2023) is, at bottom, a change in what you must be able to produce on paper — so start with the paper.
