EV Charging Gun Selection Guide: Type 2, CCS2, NACS and More
Choosing the right EV charging gun is the single most important decision for distributors, fleet operators, and aftermarket buyers entering the electric vehicle supply equipment (EVSE) market. With different connector standards across Europe, North America, and China, getting the specification wrong means costly returns, compliance failures, and lost contracts.
This guide covers every major connector type, current rating, phase configuration, cable specification, IP rating, and certification requirement you need to make informed purchasing decisions. Whether you are sourcing for a retail chain, a charging network operator, or an OEM integration project, this reference will help you match the right product to the right market.

Connector Standards: Type 2, CCS2, NACS, GB/T Compared
The global EV charging landscape is defined by several competing connector standards. Each standard was developed for a specific market and regulatory environment. Understanding which standard applies to your target market is the first step in product selection.
| Standard | Full Name | Primary Market | AC/DC | Max Current | Governing Standard |
|---|---|---|---|---|---|
| Type 2 (Mennekes) | IEC 62196-2 Type 2 | Europe, Australia, New Zealand | AC only | 63A (3-phase) / 70A (1-phase) | IEC 62196-2 |
| CCS2 | Combined Charging System Type 2 | Europe, Middle East, parts of Africa | AC + DC | Up to 500A (DC) | IEC 62196-3 |
| NACS | North American Charging Standard (SAE J3400) | North America (US, Canada) | AC + DC | Up to 500A (DC via Tesla Supercharger network) | SAE J3400 |
| CCS1 | Combined Charging System Type 1 | North America (legacy) | AC + DC | Up to 200A (DC) | IEC 62196-3 / SAE J1772 |
| GB/T | Chinese National Standard (GB/T 20234) | China | AC + DC | Up to 250A (AC) / 800A (DC) | GB/T 20234 |
| CHAdeMO | Charge de Move | Japan (legacy, declining) | DC only | Up to 400A | JEVS G105-1993 |
Key takeaway: For European market entry, Type 2 and CCS2 are mandatory. For North America, NACS is rapidly becoming the dominant standard following the US Department of Transportation’s 2024 designation. The IEC 62196-2:2022 standard (published by the International Electrotechnical Commission) defines the dimensional compatibility requirements for all AC pin and contact-tube accessories used in EV charging.
16A vs 32A: Power Rating Selection
Current rating directly determines charging speed and the electrical infrastructure required. Here is how the two most common ratings compare:
| Parameter | 16A Single-Phase | 32A Single-Phase | 32A Three-Phase |
|---|---|---|---|
| Max Power | 3.7 kW | 7.4 kW | 22 kW |
| Typical Use Case | Home charging, overnight top-up | Home/workplace, faster charging | Commercial, fleet, public charging |
| Required Cable | 3-core 2.5 mm² | 3-core 6 mm² | 5-core 6 mm² |
| Full Charge Time (60 kWh battery) | ~10 hours | ~5 hours | ~3 hours |
| Installation Cost | Lowest | Moderate | Highest |
Recommendation: For residential and light commercial applications, 32A single-phase offers the best value. For fleet operators and public charging deployments, 32A three-phase (22 kW) is the industry standard in Europe.
Single-Phase vs Three-Phase Charging
The choice between single-phase and three-phase charging depends on your target market’s electrical infrastructure:
- Single-phase (230V): Standard in North America and the UK. Most residential properties have single-phase supply. Maximum practical output is 7.4 kW at 32A. Suitable for home chargers and light commercial use.
- Three-phase (400V): Standard across continental Europe, Australia, and most of Asia. Delivers up to 22 kW at 32A. Required for workplace chargers, public charging points, and fleet depots. Not available in most North American residences.
If you are distributing to the European market, three-phase compatibility is essential. Most European countries mandate three-phase charging for public installations above 7.4 kW.
Cable Length Selection Guide
Cable length affects user convenience, voltage drop, and cost. Standard lengths and their applications:
| Cable Length | Best For | Notes |
|---|---|---|
| 3 meters | Compact installations, wall-mounted chargers in garages | Minimum viable length for most installations |
| 5 meters | Standard home and workplace charging | Most popular length; balances reach and manageability |
| 7.5 meters | Public charging stations, large parking areas | Allows charging from either side of a parking bay |
| 10 meters | Fleet depots, commercial installations | Maximum recommended length to limit voltage drop below 3% |
Important: Cable lengths above 10 meters may require thicker conductors to compensate for voltage drop. Always calculate voltage drop based on cable length, current rating, and conductor cross-section.
IP Ratings: Protection for Every Environment
Ingress Protection (IP) ratings define how well the charging gun resists dust and water. Select based on the deployment environment:
| IP Rating | Dust Protection | Water Protection | Recommended Use |
|---|---|---|---|
| IP44 | Objects >1mm | Splash from any direction | Indoor residential, covered garages |
| IP54 | Dust-protected (limited ingress) | Splash from any direction | Covered outdoor, semi-exposed workplaces |
| IP66 | Dust-tight | Powerful water jets | Outdoor public charging, exposed car parks |
| IP67 | Dust-tight | Temporary immersion (30 min at 1m) | Harsh environments, coastal areas, flood-prone zones |
For public and commercial installations, we recommend a minimum of IP66. For marine environments or areas with heavy rainfall and flooding risk, IP67 provides maximum protection.
Certification Matching: Market by Market
Every target market has specific certification requirements. Selling non-compliant products can result in customs seizure, product recalls, and legal liability. Here is the certification-to-market mapping:
| Certification | Required Market | Covers | Our Status |
|---|---|---|---|
| CE | European Union (27 countries) | Safety, EMC, RoHS compliance | Certified |
| UKCA | United Kingdom (post-Brexit) | UK equivalent of CE marking | Certified |
| UL | North America (US, Canada) | Safety per UL 2251/2252 standards | Certified |
| CCC | China | China Compulsory Certification | Certified |
| RoHS | EU, UK, global | Restriction of hazardous substances | Compliant |
| REACH | EU | Chemical safety regulation | Compliant |
Our products carry CE, UKCA, UL, CCC, RoHS, and REACH certifications. We also hold IATF 16949, ISO 9001, ISO 14001, and ISO 45001 management system certifications. See our full certifications page for documentation.
