Direct Answer
Choose a single-phase Type 2 charging cable when the charging point provides 230V AC on one live conductor and the vehicle's onboard charger accepts single-phase AC. Choose a three-phase Type 2 charging cable when the supply is 400V AC three-phase and the vehicle can charge across three phases.
The Type 2 connector interface is the same in both cases (IEC 62196-2). What changes is the number of current-carrying conductors inside the cable, the conductor cross-section, and the maximum power the cable is intended to carry.
As a practical reference, a single-phase cable at 16A is typically associated with roughly 3.7kW, a single-phase cable at 32A with roughly 7kW, and three-phase cables at 16A/32A with roughly 11kW/22kW — assuming the supply and the vehicle onboard charger can actually del
Key Takeaways
- Confirm the supply - single-phase or three-phase, nominal voltage, and the rating of the upstream protection device.
- Confirm the vehicle's onboard charger - single-phase only, or single-phase plus three-phase capability.
- Confirm the maximum AC current the installation is designed for - 16A or 32A.
- Confirm the connector on both ends - Type 2 to Type 2, or a different connector combination.
- Confirm the application - home wallbox, workplace, destination charging, fleet, or public AC charging.
- Confirm the environment - indoor, outdoor, sheltered, or exposed to salt spray and temperature extremes.

Buyer Checklist
- A single-phase cable cannot deliver three-phase power. If a buyer orders single-phase cables for a market with 400V three-phase residential or commercial supplies and three-phase-capable vehicles, the cable becomes the bottleneck.
- A three-phase cable may be unnecessary cost where the supply is single-phase only, or where the target vehicles charge on one phase.
- Market conditions differ. Single-phase 230V supplies are common in residential settings in many markets, while three-phase 400V supplies are more typical in certain countries, larger homes, commercial buildings and fleet depots.
- Distributors usually need both. A mixed portfolio lets an installer or retailer match the cable to the actual installation instead of forcing one variant across every project.
- Cable length affects performance. Longer runs increase voltage drop. The right cable length is a project decision, not only a catalogue decision.
Detailed Answer
Choose a single-phase Type 2 charging cable when the charging point provides 230V AC on one live conductor and the vehicle's onboard charger accepts single-phase AC. Choose a three-phase Type 2 charging cable when the supply is 400V AC three-phase and the vehicle can charge across three phases.
Key Industry Insights
Choose a single-phase Type 2 charging cable when the charging point provides 230V AC on one live conductor and the vehicle's onboard charger accepts single-phase AC. Choose a three-phase Type 2 charging cable when the supply is 400V AC three-phase and the vehicle can charge across three phases.
FAQ
Can I use a three-phase Type 2 cable on a single-phase wallbox?
Physically, a Type 2 connector can mate. Whether charging proceeds and at what power depends on the wallbox design, the vehicle, and how the cable is wired and detected. The unused conductors simply do not carry current. This should be confirmed against the specific product documentation before relying on it.
Can a single-phase cable deliver 22kW?
No. 22kW AC charging requires a three-phase supply. A single-phase cable at 32A is generally associated with roughly 7kW at 230V nominal.
Does my car need a three-phase onboard charger?
Yes, for three-phase AC charging. Many EVs accept only single-phase AC. The onboard charger rating is usually the practical ceiling, regardless of what the cable or wallbox supports.
Is the Type 2 connector the same on both cable types?
Yes. The Type 2 interface is defined by IEC 62196-2. The difference between a single-phase and a three-phase cable is the internal conductor count and cross-section, not the plug shape.
What cable length should I choose?
This depends on the parking position, the mounting point, and acceptable voltage drop. Longer cables lose more voltage at the same current, so length should be matched to the installation rather than chosen purely for convenience.
What IP rating should I look for?
The knowledge base cable data lists IP54 when the protective cover is connected and IP55 when plug and socket are mated. Installations exposed to rain, dust or coastal conditions should be reviewed against the actual site environment.
Do distributors need to stock both variants?
In most markets, stocking both single-phase and three-phase variants reduces the risk of mismatching an installation. The right mix depends on the grid characteristics and vehicle mix in each market.
How do I confirm the correct cable for a specific project?
Match four items together - the supply phase configuration and voltage, the upstream protection rating, the vehicle onboard charger capability, and the cable's rated current and conductor arrangement. If any of these is unclear, verify before ordering.
