What changed in the 2027 edition, and what it costs you.

The 14th edition of NFPA 70E was released digitally through NFPA LiNK in May 2026 and is the current governing edition. Most of the change set is clarification. Three items will change how you staff, document and sign work — and one will invalidate paperwork you already have.

§ At a glance

§ The additional person requirement

When it triggers

• A permit has been issued — energized work has been justified.
• And the permit specifies shock PPE, arc flash PPE, or both.
• It does not trigger where no permit is required — work within normal operating parameters, or diagnostic work that requires no PPE.

Who the additional person can be

• They do not need to be a qualified electrical worker.
• They must meet the emergency response training of 110.4(C)(1) — CPR and AED, release of a victim from contact, and knowing where rescue equipment is.
• Their role is emergency support: call for help, initiate first aid, use non-conductive rescue tools.
• They must be outside the greater of the two boundaries — close enough to respond, far enough not to become the second casualty.

§ Definitions — Article 100

§ Article 110 — General requirements

Sub-50 V hazards now in scope — 110.2(B)

The prior edition was widely read as putting systems below 50 V outside the ESWC requirement. The 2027 edition requires an electrically safe work condition wherever an electrical hazard exists, regardless of voltage. Battery systems, 24 V and 48 V control circuits, and current transformer secondaries can all present serious hazards below 50 V, because the hazard is the available current, not the voltage.

LOTO audit intervals split — 110.3(L)(3) and (L)(4)

If your program and procedures live in one combined document, consider separating them so the two audit cycles can run independently.

Employee work practices audit — 110.3(L)(2)

"Field work audit" is now "employee work practices audit," and the benchmark is explicitly the employer's electrical safety program. The word change from field to employee broadens who falls inside the audit scope.

Test instrument inspection — 110.6(D)

Split into two explicit requirements: visually inspect portable test instruments for defects, and remove from service until repaired where a defect could expose an employee to injury. A damaged meter that reads a false zero is how a qualified person gets killed on a circuit they believed was dead.

§ Article 120 — Establishing an ESWC

• 120.2(A) — the LOTO program must now be documented. "Establish, document, and implement." Documentation was implied before; it is explicit now.
• 120.3(C) — "eliminate or minimize." The word eliminate was added to the control-of-energy requirement. This is the hierarchy of controls written into the text: de-energization is the preferred outcome, and energized work is the exception.
• 120.4(D)(3) — the nylon cable tie specification is gone. Tagout device material must now be suitable for the environment where it is used. Update any spec sheet that says "nylon cable tie."
• 120.5(B)(6) — additional testing where voltage testing is inconclusive. The most safety-critical change in Article 120. Some circuits carry near-zero voltage and dangerous current — current transformer secondaries and series airfield lighting are the classic cases. Where absence-of-voltage testing alone does not establish that the conductors are de-energized, additional testing is required; absence-of-current testing is given as an example.
• 120.5(B)(7) — retitled from "grounding" to "temporary protective grounding," removing an ambiguity that had real consequences in the field.

§ Article 130 — Work involving electrical hazards

The article was restructured

Scope text formerly in 130.1 moved into a new 130.2, and the energized electrical work permit moved from 130.2 to 130.3. The permit requirements themselves did not change technically — but every procedure, form and training slide that cites "130.2(B)" for the permit is now citing the wrong section.

Contact thermal hazard hand protection — 130.7(C)(7)(e)

New requirement: thermal hand protection where exposure to a contact thermal hazard is possible. This is protection against a burn, not against shock — rubber insulating gloves do not satisfy it, and thermal gloves do not satisfy the shock requirement. Two different hazards, two different gloves, and in a battery room you may need both.

PPE conformity assessment — 130.7(C)(14)

The prior edition permitted three conformity methods. The 2027 edition removes supplier self-declaration, leaving two: self-declaration under a registered quality management system with accredited laboratory testing, or third-party certification by an accredited body. PPE already marked under the old self-declaration method remains permitted; this affects new purchasing.

§ Chapter 3 renumbering

The technical committee reorganized Chapter 3 because it had "evolved using a patchwork of subjects generally developed in isolation." The renumbering itself is editorial — but three genuinely new articles came with it.

Article 360 — batteries, four hazard categories

The battery article now requires the risk assessment to address four separate hazard categories, each with its own PPE determination: chemical, contact thermal, electric shock, and arc flash. Thresholds are codified:

Battery room warning signs must now carry a thermal hazard warning in addition to shock and arc flash, plus chemical warnings and a PPE/access notice. Full Article 360 page →
