11kW (16A Three-Phase) EV Charging Cables

11kW cables (16A three-phase) are a step up from 7kW, but only if your property actually has a three-phase supply. Most UK homes are single-phase, so check before you buy. Where three-phase is available, an 11kW wallbox and a matching cable nearly doubles your home charging speed.

Three-phase supply required. Three-phase electricity is rare in UK domestic settings, and most homes are single-phase. Check with a qualified electrician before ordering. A three-phase wallbox on a single-phase supply will not work at full speed and may not work at all.

Matching cable power to wallbox and supply

An 11kW EV charging cable runs at 16A three-phase, the middle option between 7.4kW (single-phase) and 22kW (full three-phase). It's the right answer for UK three-phase homes paired with an EV that accepts 11kW AC but not 22kW, which is most of them, including BMW, VW Group, Mercedes, Tesla and Polestar.

When 11kW is the right choice

Two conditions need to be met:

  1. Three-phase supply at your property: most UK homes are single-phase. Confirm with a qualified electrician.
  2. Your EV accepts 11kW AC: most modern EVs do. The list of 11kW-only cars (won't take 22kW) is long: BMW i3 refresh, i4, i5, i7, iX1, iX3, iX; VW ID.3, ID.4, ID.5, ID.7; Audi Q4 e-tron, Q6 e-tron; Mercedes EQA, EQB, EQE, EQS; Tesla Model 3, Model Y; Polestar 2, 3, 4; Volvo EX30, XC40 Recharge; Hyundai Ioniq 5, 6; Kia EV6, EV9; Nissan Leaf Mk3.

If condition 1 isn't met, you don't need 11kW, go with 7.4kW single-phase. If condition 2 isn't met (your car accepts 22kW), step up to 22kW.

What 11kW means for charge speed

At 11kW three-phase you add ~45 miles of range per hour, vs 25-30 at 7kW single-phase. A 60kWh battery refills 10-100% in about 5 hours, vs 8 hours on single-phase. For typical UK commuter use (50-mile daily mileage), the difference is small, both refill comfortably overnight. For high-mileage drivers (taxi, sales, fleet) the 1.5-3 hour saving each charge cycle adds up materially.

Connector type

Type 2 (Mennekes): same connector at both ends as 7kW and 22kW. The cable wires up all three phase pins; on a single-phase wallbox it'll throttle to 7.4kW automatically.

Cable build vs 7kW

11kW cables use the same conductor cross-section as 22kW (typically 4mm² per phase) because the current-carrying capacity per phase is 16A, same as a single-phase 16A circuit. The cable is heavier than a 7kW single-phase cable but lighter than a full 32A 22kW three-phase cable.

Length considerations

Three-phase cables are heavier per metre. Pick the shortest cable that works for your driveway:

  • 5m: wallbox close to parking spot. Easy to coil.
  • 7.5m or 10m: typical UK three-phase driveway with the wallbox on the garage wall.
  • 15-20m: long driveways or shared. Note 15m three-phase cables are 8-10kg.

Build quality

  • IEC 62196-2 compliance on the connector.
  • IP55 minimum on couplings: IP66 if you'll leave plugged in during storms.
  • Halogen-free woven jacket: survives UK weather 5-10× longer than rubber.
  • 2-year minimum manufacturer warranty.

Pairing with the right wallbox

  • MyEnergi Zappi 22kW: three-phase, native solar diversion. Ideal for UK three-phase solar homes.
  • Easee One 22kW: load-balancing across multi-EV setups.
  • Wallbox Pulsar Plus 22kW: Power Boost dynamic load management.
  • Project EV Pro Earth 22kW: best-value three-phase option at £799.

Three-phase upgrade: when worth it

Upgrading from single-phase to three-phase costs £3,000-8,000 typically, takes 6-16 weeks, and may not be possible everywhere (LV grid capacity constrained in some areas). Worth it if you also run heat pumps, electric AGAs, induction hobs and batteries that benefit from three-phase distribution. Not worth it solely for EV charging: the 1-2 hour overnight saving doesn't justify the capex on a single 7kW vs 11kW comparison.

What it won't do

Won't speed up a single-phase wallbox: supply caps the speed. Won't charge from public DC rapid (CCS): those are tethered to the rapid post. Won't make a 22kW-capable EV charge faster than 11kW unless your wallbox is also 22kW.

Questions

Will my wallbox use the full speed of this cable?
Only if the wallbox is rated equal or higher. A 32A cable on a 16A wallbox throttles to 16A. Check your wallbox spec: most UK home wallboxes are 32A (7kW) or 32A three-phase (22kW).
Do I have a three-phase supply?
Most UK domestic supplies are single-phase. If you're not sure, check your distribution board or ask a qualified electrician. Single-phase = one live wire; three-phase = three live wires (typically only newer or larger UK builds).
Will a higher-power cable damage my car?
No. The car requests current from the cable based on what it can accept. A 32A cable on a car that asks for 16A simply delivers 16A.
How long does delivery take?
In-stock items ship same-day if ordered before 16:00 on a working day. Standard delivery is next-working-day across mainland UK. Northern Ireland, Channel Islands and remote Highlands take 2-3 working days. Free delivery on orders over £150.
What warranty do these come with?
Every product on our shelf carries a minimum two-year manufacturer warranty. We administer warranty claims directly: ship the replacement next-day and collect the original at no cost to you.
