Connector Interface: GB/T 20234 Versus IEC 62196 China EVSE commonly uses GB/T 20234.1-2023, GB/T 20234.2-2015, and GB/T 20234.3-2023 connector interfaces. These are not automatically interoperable with IEC 62196 Type 2 or CCS configurations, and adapters should not be assumed acceptable for public or fleet charging unless the electrical, communication, locking, safety, and liability requirements are approved.GB/T 20234.1-2023
GB/T 20234.2-2015
GB/T 20234.3-2023		 Tunisia projects may specify IEC 62196 connector configurations, often through buyer, fleet, public-charging, or engineering requirements rather than a single public national EV-charger connector mandate. IEC 62196 covers plugs, socket-outlets, vehicle connectors, and vehicle inlets for conductive EV charging; the exact Type 2, CCS, CHAdeMO, or other interface should be confirmed in the tender, vehicle fleet, and site design.IEC 62196 series
IEC 62196-1
IEC 62196-2
IEC 62196-3		 Lock the export connector bill of materials before shipment. Confirm the vehicle inlet population in Tunisia, AC and DC connector type, cable assembly rating, locking and proximity functions, communication protocol, adapter policy, replacement parts, and labeling language.[INFORMATIONAL] Connector shape is a market-access issue, not a paperwork translation issue. A charger using GB/T 20234.1-2023, GB/T 20234.2-2015, and GB/T 20234.3-2023 should be treated as a different interface unless Tunisia project documents expressly accept it.

50 Hz Tunisia Electrical Configuration China EVSE is commonly designed for 50 Hz operation, so frequency is often not the largest gap. The remaining risk is the export variant: input voltage range, three-phase configuration, protective devices, EMC filtering, metering, cable sizing, cooling, and software limits must match the Tunisia installation.GB/T 18487.1-2023
Factory electrical ratings
Export model installation manual		 Tunisia grid-connected EVSE should be configured and documented for the local 50 Hz electricity system and the actual supply arrangement at the site. Confirm nominal voltage, phase configuration, neutral and earthing system, protective-device coordination, leakage-current protection, thermal derating, and power-quality limits with the installer and STEG connection documents.STEG site connection conditions
Project electrical-installation approval documents
IEC 61851 EVSE ratings and installation information where required		 Do a configuration review rather than a standards-only review. Check nameplate values, firmware current limits, upstream breaker sizing, RCD or RDC-DD strategy, surge protection, enclosure thermal performance, and commissioning tests under the Tunisia supply arrangement.[INFORMATIONAL] 50 Hz compatibility is necessary but not sufficient. Confirm the full Tunisia electrical configuration before shipment and before energization. Societe Tunisienne de l'Electricite et du Gaz (STEG)2026-06-14 · unverified
China GB/T 18487 Evidence Versus Tunisia IEC-Route Review GB/T 18487.1-2023 is the current China baseline for conductive charging-system general requirements, replacing the 2015 edition. China files may also include GB/T 18487.2, GB/T 20234 connector reports, GB/T 27930 DC communication evidence, EMC reports, and factory routine-test records.GB/T 18487.1-2023
GB/T 18487.2
GB/T 20234 series
GB/T 27930		 Where Tunisia project documents request IEC-route EVSE evidence, the target review should be based on the exact IEC 61851 edition, any INNORPI adoption or buyer specification, and the site electrical approval route. A China GB/T 18487 report may be technically relevant but should be translated into a clause-by-clause comparison with stated deviations.IEC 61851-1:2017
IEC 61851-21-2:2018
IEC 61851-23 where DC EVSE is in scope
INNORPI-adopted or project-specified standards where applicable		 Build a dossier index that separates China conformity, IEC technical mapping, connector interface, EMC evidence, installation manual, grid input assumptions, cybersecurity or communications features if present, and Tunisia site-specific approvals. Do not collapse all of these into one 'GB/T compliant' claim.[INFORMATIONAL] GB/T 18487 evidence is a starting point for Tunisia, not the conclusion. Provide an edition-specific GB/T-to-IEC bridge and keep site approval evidence separate.

INNORPI Standards Route and IEC 61851 EVSE Safety Baseline China commonly uses GB/T 18487.1-2023 as the conductive charging-system baseline. It can support a Tunisia technical file only after edition comparison and clause mapping to IEC 61851 or any INNORPI-adopted, tender, owner, installer, or authority requirement.GB/T 18487.1-2023
GB/T 18487 series		 Tunisia EV charger projects should confirm whether INNORPI has adopted, referenced, or accepted an IEC-route standard for the charger scope, including the Tunisia NT 40.276 EV-charging series where cited, and whether the buyer, tender, customs route, installer, or authority requires IEC 61851 evidence. IEC 61851-1:2017 covers EV supply equipment operating characteristics, the EVSE-to-EV connection, and electrical safety for EVSE up to the IEC stated 1,000 V AC or 1,500 V DC supply limits.INNORPI national standards route where adopted or required
Tunisia NT 40.276 EV-charging series where adopted, cited, or required
IEC 61851-1:2017
IEC 61851 series for electric vehicle conductive charging systems		 Prepare IEC 61851 test evidence or a defensible GB/T-to-IEC matrix covering ratings, protection functions, control pilot behavior, earthing, insulation, emergency stop or shutdown behavior, markings, manuals, and installation instructions.[INFORMATIONAL] Treat NT 40.276 / IEC 61851 as the Tunisia technical baseline only when INNORPI, a tender, buyer, installer, STEG, customs route, or project owner makes it applicable. GB/T 18487 evidence should be mapped, not renamed. International Electrotechnical Commission (IEC)2026-06-14 · unverified
Tunisia EV Policy and Incentive Context China-side documentation may cite China new-energy vehicle policy, GB/T charging standards, and domestic charging-infrastructure practice. This background is commercially useful but does not establish Tunisia import, tax, customs, installation, or utility acceptance.China EV charging policy materials
GB/T 18487 series
GB/T 20234 series		 Tunisia energy and transport policy supports lower-carbon transport and energy-efficiency objectives through public bodies such as the Ministry of Energy and Mines and ANME. Policy signals, incentives, or fleet programs can drive charger demand, but they should not be treated as a charger product approval unless the exact legal, customs, tax, tender, or installation document says so.Tunisia Ministry of Energy and Mines energy policy materials
ANME energy-efficiency and transport-sector programs
Project-specific EV or fleet tender documents where applicable		 Separate policy incentives from technical approval. For each Tunisia opportunity, identify the actual importer of record, tariff and tax route, site owner, utility connection route, public-procurement conditions, and any standard or certificate named in the tender.[INFORMATIONAL] Tunisia EV policy can create demand or incentives, but it does not by itself prove charger conformity. Tie every claim to the specific tender, permit, import, tax, or STEG condition. Agence Nationale pour la Maitrise de l'Energie (ANME)2026-06-14 · unverified
STEG Grid Connection and Site Electrical Approval China-side factory files may include GB/T 18487, GB/T 20234, EMC reports, and grid input ratings. These do not replace Tunisia site load studies, STEG connection approval, local protection settings, earthing design, metering requirements, or installer sign-off.GB/T 18487.1-2023
Factory input-rating and protection documentation
China project grid-connection documents where available		 EV charger installations in Tunisia should be coordinated with STEG or the relevant site electricity authority for service capacity, connection works, tariffs, metering, protection, earthing, load management, and any medium-voltage or low-voltage connection conditions. STEG's public portal identifies electricity connection, tariffs, procedures, and protection-relay approval topics, but the binding requirements are normally project and connection-point specific.STEG electricity connection and service procedures
STEG tariff and metering requirements where applicable
Project electrical-installation approval documents		 Before installation, obtain the actual Tunisia connection conditions and prepare a single-line diagram, load schedule, harmonic or power-quality evidence where requested, protection coordination, earthing plan, metering plan, and commissioning procedure aligned with STEG and site requirements.[INFORMATIONAL] Do not ship a high-power EVSE configuration on factory ratings alone. Tunisia energization depends on the actual STEG or site connection route and approved installation design. Societe Tunisienne de l'Electricite et du Gaz (STEG)2026-06-14 · unverified
