625.43 - EVSE Emergency Disconnect - 2026 NEC Changes

I don't understand the link to that public comment. The language in the 2026 code does not require an emergency disconnect for one and two family dwellings. It appears that all the PC was asking was to eliminate the emergency disconnect for one and two family dwellings.

The language changed
The real issue I have with e-Stop is twofold: for multifamily garages which got forgotten,
and for public fast charging because of the manual reset requirement.

All E-stop type systems need to have a manual reset for safety. I understand the issue with a malicious push of the emergency shut down button, and since this is really only for first responders, the button should be in a knoxbox type enclosure. However that would need the approval of the local AHJ or a code change.

As far as multifamily garages, I am not sure that EV charging should even be permitted in a multifamily garage where the garage is part of the residential building. There is a serious potential issue, and that is illustrated by one of the major insurers in the US taking action last year to remove all EV chargers from their parking garages and place them in open outside parking areas.

Insurance companies will do anything and everything to avoid paying a claim. It doesn't matter how remote the possibility of an incident, only how definable it is. There may be a hundred other things that are harder to define or enforce and more likely to cause a fire that will never be moved outside.

This was at their own facilities, they have not extend that rule to their insured properties, as far as I know. I expect,based on claims, the insurance companies have better knowledge than any other organization on these types of issues.
 
“ The disconnecting means shall be lockable open… “. Isn’t the shunt only a means to trip breaker but breaker still can be switched back on. Are there shunt trips that won’t allow manual reset of breaker (?)

This thread is about the emergency shutoff in 625.43(D) and not the equipment disconnect in 625.43(C). The lockable open language is found in (C), but not in (D).

The rule for the emergency shutoff would permit a shunt trip, as turning the breaker back on after the shunt trip device has opened it, is a manual reset. All manual reset means is that some physical action must be taken to restore power. The act of turning the breaker back on is a physical action.

There have been a number of fires at charging stations, not a lot, but enough that I, as a former first responder, would welcome a way to kill the supply power to the chargers, even though I know that if a battery is on fire, the charger should automatically stop supplying power to the battery.

Right. 625.43(D) requires a manual shutoff.
But EVSE already have an automatic shutoff in case of a battery on fire.
Once the BMS detects the battery is out of specification (and when it's on fire that's happening) it drops CP, and the EVSE shuts off.

Subject: NFPA---NOTIFICATION of FAILED Ballot for Proposed TIA No. 1874 to
NFPA 70, 2026 edition

February 6, 2026

As a submitter of a public comment, this email is to notify you that
proposed Tentative Interim Amendment (Log No. 1874) 70®, *National
Electrical Code®, *2026 edition, revising section/paragraph 625.43(D), has
failed ballot of the NEC Code-Making Panel 12 on both technical merit and
emergency nature. However, it did pass ballot of the NEC Correlating
Committee for correlation issues.

Fourteen (14) public comments were received by the public comment closing
date of January 27, 2026, and were circulated to the Panel and Correlating
Committee members for possible change in vote. Additionally, one late
public comment was received after the public comment closing date of
January 27, 2026, and will be included on the agenda for the Standards
Council’s review of the entire record for this TIA.....

Subject: Appeal on TIA Log No. 1874 – Request for Balanced Task Group Formation
To: <stds_admin@nfpa.org>

Dear NFPA Standards Council Secretary,
I am writing to express concern regarding the recent failure of TIA Log No. 1874 (NEC 625.43(D)) to pass ballot within Code-Making Panel 12. While the TIA was ultimately rejected on technical merit and emergency nature, I believe this outcome reflects a deeper procedural gap—namely, the absence of a balanced task group to consider the broader stakeholder perspectives necessary for good code.
