Electrical Code & NRTL (ETL) Listing
The most universal compliance requirement in EV charging has nothing to do with grants: no authority having jurisdiction will pass an unlisted charger. ETL listing is the same NRTL pass/fail as UL — and it is also a baseline eligibility requirement in most funding programs.

- Standing requirement
- When it applies
- Every charger installation, everywhere, regardless of funding — electrical codes and inspectors require NRTL-listed equipment installed per NEC Article 625.
- Whose obligation
- The manufacturer provides listed equipment; the installer and owner must use listed equipment and install it to code under permit.
- ZEF's status
- ZEF Level 2 and DC fast chargers are ETL-listed.
What NRTL listing means
OSHA recognizes a set of Nationally Recognized Testing Laboratories (NRTLs) that certify products to U.S. safety standards. ETL (Intertek) and UL are both NRTLs; an ETL listing to the relevant EVSE safety standards carries the same weight with electrical inspectors as a UL listing. What matters to the authority having jurisdiction is the NRTL mark, not which lab issued it.
Code, permits, and program eligibility
EV charging installations fall under NEC Article 625 (as adopted, with amendments, by each state or locality), plus permitting and inspection by the local authority having jurisdiction. Listed equipment installed by qualified electricians under permit is the baseline — a standing requirement no funding source waives.
Listing also shows up as a funding-attached requirement by reference: most state, utility, and federal programs make NRTL listing an eligibility condition for rebated or granted equipment. Unlisted hardware fails both the inspector and the grant application.
Frequently asked questions
Is ETL listing equivalent to UL listing?
For code and inspection purposes, yes. ETL (Intertek) and UL are both OSHA-recognized NRTLs; either mark on equipment certified to the relevant safety standards satisfies the listing requirement.
Do grant programs require listed chargers?
Almost universally — most state, utility, and federal programs make NRTL listing an eligibility condition, on top of the electrical code requirement that applies regardless.
