Code Change Summary: New code section 625.5 requires specific field marking for electric vehicle charging equipment.

SME commentary: In the 2026 NEC^®, new Section 625.5 was added to require field marking for electric vehicle supply equipment (EVSE). The new language on field marking in 625.5 requires the following permanent markings on the outside of the EVSE equipment enclosure which must be visible after installation:

(1) Supply voltage, number of phases, frequency, and full-load current for each incoming supply circuit

(2) Short-circuit current rating of the electric vehicle supply equipment based on either the SCCR  of a listed and labeled assembly, or the SCCR established utilizing an approved method.

A new informational note directs the code reader to UL 2594 (safety standard for EVSE) as an example of determining the SCCR using “an approved method”.

While EVSE is evaluated under UL 2594, the standard did not specifically require the SCCR to appear on the EVSE nameplate when new 625.5 was added to the NEC^®. It is critical to know the short-circuit current rating of the equipment and have it marked where readily visible so the AHJ can confirm that it is installed properly, safely, and in compliance with NEC^® 110.10.

An important factor that influenced the words “field marking” in the title of new 625.5 is that EVSE may have an adjustable current setting as permitted in 625.42(B). When adjustments are made, the rating label must reflect the actual setting. The Code gives clear direction that if the adjusted current setting affects the rating label, the revised setting must appear on the field-installed label in accordance with 110.21. This ensures that the values displayed on the enclosure match the conditions the equipment will operate under.

Similar marking and SCCR practices have been required for years throughout the Code for industrial control panels, HVAC equipment, switchgear, switchboards, panelboards, surge protective devices and more. These new marking requirements for EVSE reinforce consistency across equipment types and give the AHJ the information needed to verify compliance with NEC^® 110.10.

2026 Code Language:

N 625.5 Field Markings. EVSE shall have the following permanent markings on the outside of the equipment enclosure that are visible after installation:

(1) Supply voltage, number of phases, frequency, and full-load current for each incoming supply circuit

(2) SCCR of the electric vehicle supply equipment based on one of the following:

a. The short-circuit current rating of a listed and labeled assembly

b. The short-circuit current rating established utilizing an approved method

Informational Note: See UL 2594, Standard Electric Vehicle Supply Equipment, for an example of an approved method.
