Compliance is mandatory

NFPA 70B (2023) is enforceable. Here's the standard that says so.

NFPA 70B (2023) — the standard that governs how you maintain electrical equipment — is no longer a recommended practice. It now uses “shall” language throughout, which means an inspector, an auditor, or your insurance carrier can hold you to it. OSHA's General Duty Clause (Section 5(a)(1)) and 29 CFR 1910.303(b)(1) already require electrical equipment to be maintained in a safe condition. NFPA 70B (2023) is the recognized standard by which that obligation is measured. If you operate a commercial building with electrical equipment, you need a documented Electrical Maintenance Program. This page explains what that looks like, where the obligation comes from, and how EZ70B helps you produce one.

NFPA 70NFPA 70BNFPA 70ENFPA 73
NFPA 70NEC

How electrical systems must be installed.

The National Electrical Code. Governs how wiring, panels, outlets, and equipment are installed. Adopted regionally — Kentucky and its cities adopt specific editions (2017, 2020, or 2023).

What it requires of owners

That any installation or modification meets the locally-adopted edition of the NEC.

How EZ70B helps

Our technicians check your installed equipment against the NEC edition adopted by your AHJ (Authority Having Jurisdiction).

NFPA 70BThe big one

How electrical equipment must be maintained.

The standard for ongoing maintenance of electrical equipment. Shifted from "recommended practice" to enforceable standard in 2023 — a forty-year change in regulatory weight.

What it requires of owners

A formal Electrical Maintenance Program (EMP), annual infrared thermography, a short-circuit / coordination study every 5 years, and complete documentation.

Why insurers care

Property carriers increasingly treat 70B compliance as a condition of coverage or a factor in premium and loss-control credit.

How EZ70B helps

We run the recurring inspection cadence, produce the documentation, and deliver the PE-signed reports insurers want to see at renewal.

NFPA 70EWorker safety

Electrical safety for people working on the equipment.

Worker-safety standard covering PPE, arc-flash boundaries, and lockout/tagout. Mostly applies to our technicians on your site, not to you as a building owner.

How EZ70B helps

Our licensed electricians and PE operate under 70E whenever they are on your property. Arc-flash PPE categories are numbered 1 through 4 — not A / B / C / E, a common misconception.

NFPA 73Residential

Electrical inspections for existing dwellings.

Specifically covers inspection and testing procedures for existing 1- and 2-family homes, multi-family dwellings with 3 or more units, and mobile / manufactured homes.

How EZ70B helps

Our apartment-complex survey and inspection flows are built directly from NFPA 73's procedures, extended with 70B's maintenance requirements.

How the four fit together.

EZ70B sits at the intersection of 70B and 73 for multi-unit buildings. We lean on 70 as the installation baseline and operate under 70E whenever our technicians are on your site.

OSHA: why the underlying obligation already exists

Most building owners think NFPA 70B is the entire compliance question. It isn't. The underlying obligation to maintain electrical equipment in safe condition is already written into federal law — and OSHA has been enforcing it for decades.

OSHA Section 5(a)(1) — the General Duty Clause

“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.”

OSHA inspectors use the General Duty Clause to cite employers for unmaintained electrical equipment when no more specific rule applies.

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.”

The specific rule that applies to most commercial electrical systems.

What NFPA 70B (2023) changed isn't whether you have to maintain electrical equipment — that was already true. It changed how the recognized standard for satisfying that obligation reads. “Should” became “shall.” An employer who can't produce a written Electrical Maintenance Program aligned with NFPA 70B now has a much harder defense in an OSHA citation, an insurance claim dispute, or a wrongful-injury suit.

Insurers: why your carrier increasingly asks for 70B records

After the 2023 edition of NFPA 70B was published, property and equipment-breakdown carriers began updating underwriting guidelines. Several national carriers now ask risk-managed accounts for evidence of a documented Electrical Maintenance Program at renewal, and loss-control engineers increasingly use NFPA 70B as the framework for their site assessments.

The pattern, in plain terms:

  • At underwriting. Some carriers ask for an attestation that you have an EMP. Some ask for a sample of inspection records. Some send a loss-control engineer to walk your gear and produce a recommendation framed against 70B.
  • At claim time. When a transformer fails, a switchgear bus arcs, or a panel catches fire, the claim investigation asks: was this maintained? An undocumented “yes” is not the same answer as a 70B-aligned inspection record with dates, findings, and corrective actions.
  • At renewal. Loss-control credits and deductible levels increasingly attach to documented EMP evidence.

Specifics vary by carrier, by book of business, and by renewal cycle. The constant: a documented EMP is becoming the baseline expectation, not the bonus. (Ask your broker. They have a stake in the answer.)

Frequently asked questions

Direct answers to the questions building owners ask when they first read about NFPA 70B.

Is NFPA 70B actually mandatory?
The 2023 edition of NFPA 70B was reclassified from a Recommended Practice to a Standard, with "shall" language throughout. Standalone, NFPA 70B is enforceable wherever an Authority Having Jurisdiction (AHJ) adopts it by reference (a growing list of states and municipalities are doing so). Independently, OSHA's General Duty Clause and 29 CFR 1910.303(b)(1) already obligate employers to maintain electrical equipment in safe condition — and OSHA uses NFPA 70B as the recognized industry standard for measuring whether that obligation has been met. Practically: if you operate a commercial building with electrical equipment, you need a documented Electrical Maintenance Program. Calling that "mandatory" overstates the legal mechanism but accurately describes the operational reality.
Does OSHA require electrical equipment maintenance?
Yes. 29 CFR 1910.303(b)(1) requires that electric equipment be "free from recognized hazards that are likely to cause death or serious physical harm to employees," and OSHA's General Duty Clause (Section 5(a)(1) of the OSH Act) compounds this. OSHA inspectors increasingly use NFPA 70B as the recognized industry standard for evaluating whether your maintenance is sufficient. A maintenance-induced equipment failure with no documented program behind it is a citation waiting to happen.
Does my insurance company require NFPA 70B?
Increasingly, yes — especially for property and equipment-breakdown coverage. After the 2023 edition was published, several national carriers updated underwriting guidelines to request documented Electrical Maintenance Programs aligned with NFPA 70B for risk-managed accounts and loss-control credits. Specifics vary by carrier and by renewal cycle. Ask your broker; they have a stake in the answer.
What changed in NFPA 70B 2023?
Three significant shifts. (1) The document was reclassified from a Recommended Practice (RP) to a Standard, meaning "should" language was replaced with "shall" throughout. (2) It now requires a written Electrical Maintenance Program with assigned roles (EMP Coordinator, Qualified Persons). (3) Inspection cadences became more prescriptive, with explicit tables for time-based and condition-based intervals across equipment classes. The 2023 edition is also far more enforceable in tort and insurance contexts than the prior RP-class document.
What's the difference between NFPA 70 and NFPA 70B?
NFPA 70 is the National Electrical Code (NEC) — the installation standard. It governs how electrical systems are designed and installed in new construction or major renovations and is adopted as law in every US state. NFPA 70B is the electrical equipment maintenance standard — it governs how you keep what was installed under NFPA 70 working safely over time. Different documents, different audiences, both load-bearing.
How often do I need to inspect my electrical equipment?
NFPA 70B (2023) prescribes intervals by equipment class and condition. As a general starting point: switchgear and transformers are typically inspected annually; motor control centers and distribution panels every one to three years; coordination and short-circuit studies refreshed at the cadence the standard requires (and whenever the system materially changes). EZ70B's built-in maintenance library encodes these cadences and produces dashboards and alerts when assets are due.
Do I need a Qualified Person?
For most inspection and maintenance work on energized or recently-energized electrical equipment, yes. NFPA 70B defines a Qualified Person consistently with NFPA 70E: someone with documented training, current certifications, and authority delegated by the EMP Coordinator. EZ70B tracks Qualified Person training records (certification name, completion date, expiration date) per team member as part of the audit-defensibility surface.
What records does an EMP need to keep?
At minimum: a current equipment inventory with location and type, a one-line diagram of the electrical system, written maintenance procedures keyed to each equipment class, inspection event records with dates, who performed them, and findings, corrective-action tracking for every finding, training records for every Qualified Person, and copies of any coordination, short-circuit, and arc-flash studies. EZ70B is built to produce all of these as audit-ready exports.
Who is an Authority Having Jurisdiction (AHJ)?
An AHJ is the regulatory body responsible for enforcing the applicable code in your jurisdiction — typically a state fire marshal, local electrical inspector, or building official. AHJs adopt NFPA standards by reference into local code. When an AHJ adopts NFPA 70B by reference (a growing list of jurisdictions are doing so), the standard becomes statutory in that jurisdiction. Independent of any AHJ adoption, OSHA's authority is federal and already in effect.
What's the penalty for non-compliance?
Three primary channels. (1) OSHA citations under the General Duty Clause or 29 CFR 1910.303(b)(1), which carry per-violation civil penalties scaled by classification (Serious vs. Willful/Repeated) plus criminal exposure for willful violations causing fatalities. (2) AHJ enforcement: notice of violation, stop-work orders, or red-tagged equipment that can't be reenergized until the program is in place. (3) Insurance impact: premium increases, loss of loss-control credits, or denial of claims when a maintenance-induced failure can't be defended with documented inspection history. The biggest practical penalty for most operators is the claim that doesn't pay.
Does my building need a coordination study and short-circuit study?
For commercial systems with significant fault-current potential, NFPA 70B calls for both, performed by a qualified engineer (typically a licensed Professional Engineer) and refreshed when the system materially changes — for example, a new transformer, a major load addition, or replaced switchgear. These are PE-stamped engineering deliverables. EZ70B doesn't compute them — that's the engineer's job — but the platform tracks the document, the refresh cadence, and the trigger conditions that should prompt a re-study.
Can I run an EMP with spreadsheets?
Technically yes; practically no. The 2023 edition requires inspection records that link to specific assets, specific procedure steps, specific Qualified Persons, and specific finding-to-resolution paths — all auditable, all dated, all signed off. Spreadsheets break under that load within a few months and don't survive a real audit. EZ70B replaces the sprawl with a structured database that produces the records auditors, AHJs, and insurers ask for.
