Tesla Wall Connector Gen 3 7kW 22kW Type 2 Tethered EV Charger
The Tesla Wall Connector Gen 3 is Tesla's official home and workplace EV charger — and it remains one of the most capable, compact, and cost-effective wall-mounted chargers available in the UK. Delivering up to 7.4 kW on single-phase or a full 22.1 kW on three-phase supply, with a 7.3-metre tethered Type 2 cable, built-in Wi-Fi, and a sleek glass-front IP55 enclosure measuring just 345 × 155 × 110 mm, it is engineered for daily use at home, in apartments, at hospitality venues, and at workplaces. Compatible with all Tesla vehicles and every non-Tesla EV fitted with a Type 2 port, it supports power sharing across up to six units on a single circuit — making it equally effective as a single domestic installation or as a scalable multi-bay site solution. Over-the-air firmware updates via the Tesla app keep the charger current without any engineer visits, and adjustable output from 6 A to 32 A means the installer can precisely match the charger to any supply.
The Tesla Wall Connector must be installed by a qualified electrician trained to work on electrical systems (Part P registered in England and Wales). The installer is responsible for compliance with BS 7671 (18th Edition Wiring Regulations) and all applicable building regulations. Do not attempt to install this product yourself — incorrect installation can damage the vehicle's battery and voids the warranty.
Most UK homes are fed from a TN-C-S (PME) supply. Installing an EV charger on this earthing arrangement without additional protection is a mandatory requirement under BS 7671 Amendment 2. Your electrician must fit a PEN fault detection and isolation device (such as the Matt:e Single Phase Monitor), use an isolating transformer, or convert to a TT earthing system using a dedicated earth rod — the installer is fully responsible for selecting and implementing the correct solution. See the Tesla UK Earthing Application Note at the rear of the installation manual for full guidance.
The Tesla Wall Connector Gen 3 is not currently approved for the UK OZEV EV Chargepoint Grant (worth up to £500 for eligible renters and flat owners). Homeowners purchasing outright are not affected — the grant only applies to renters and flat/apartment residents. If grant eligibility is essential, please contact us and we can advise on OZEV-approved alternatives.
The Gen 3 automatically adapts to the available supply. On a standard UK single-phase 230 V supply at 32 A, it delivers 7.4 kW — adding roughly 44 miles of range per hour for a Tesla Model 3. On a three-phase 400 V supply it reaches 22.1 kW, ideal for workplaces, apartments, and three-phase domestic connections. The installer sets the maximum amperage — from 6 A to 32 A — during commissioning via the Tesla One app.
Connect the Wall Connector to your home Wi-Fi and manage everything from the Tesla app: view charging history, set scheduled charge times to coincide with off-peak tariff windows, monitor energy usage, and grant access to other users. Compatible with Octopus Intelligent Go for fully automated off-peak scheduling — set a departure time and the car and charger handle the rest.
Multiple Wall Connectors can share a single branch circuit, with the units communicating wirelessly to distribute available power intelligently between vehicles. Load balancing is continuous and automatic — as one vehicle reaches full charge, available power shifts to others. Supports up to six Wall Connectors per group, with each unit maintaining its own dedicated branch circuit and breaker as required by Tesla's installation specification.
Unlike many competitor chargers, the Wall Connector integrates a Type A RCD with DC 6 mA detection directly into the unit. AC earth fault protection trips at 20 mA; DC fault protection trips at 6 mA. This means a separate external Type B RCD is not required solely for the charger — though your installer may still fit upstream protection as part of the overall BS 7671 installation design. The built-in protection simplifies installation and reduces hardware cost.
The 7.3-metre tethered Type 2 cable is compatible with all electric vehicles fitted with a Type 2 (IEC 62196) charge port — not only Tesla models. This covers the vast majority of EVs sold in the UK and Europe, including Volkswagen, BMW, Audi, Hyundai, Kia, Nissan, Renault, Polestar, Mercedes-Benz, and many more. No adapter is needed for Tesla vehicles — the connector fits directly into Tesla's CCS port.
Temperature sensors at the relays, microcontroller, and charge handle actively monitor thermal conditions throughout every session. In high ambient temperatures, the Wall Connector automatically reduces current to protect the unit — displaying a 3-blink amber code on the LED bar. Charging resumes at full power once temperatures normalise. No user intervention required. Operating range is −30°C to 50°C, with storage rating to 85°C.
Tesla pushes automatic firmware updates over Wi-Fi to keep the Wall Connector current with new features, safety improvements, and diagnostic enhancements — no engineer visit required. Updates can also be delivered directly via a connected Tesla vehicle. The Wall Connector requires a WPA2-secured 2.4 GHz 802.11b/g/n network; it hosts its own access point (SSID printed on the rear label) for initial commissioning via the Tesla One installer app.
At just 345 × 155 × 110 mm and 6.8 kg, the Wall Connector is one of the most compact full-power chargers available. Rated IP55 (dust-tight, protected against water jets) and IK08 (impact resistance up to 5 joules), it is certified for both indoor and outdoor installation without a separate weatherproof enclosure. The glass faceplate and LED light bar give a premium finish suited to both domestic garages and customer-facing commercial locations.

Does the Tesla Wall Connector work with non-Tesla EVs?
Yes. The Gen 3 Wall Connector uses a standard Type 2 (IEC 62196) tethered cable, which plugs directly into the charge port of virtually every EV sold in the UK — including Volkswagen ID.3/ID.4, BMW iX, Hyundai Ioniq 5, Kia EV6, Nissan Leaf, Renault Zoe, Polestar 2, Mercedes EQA, Audi Q4 e-tron, and many more. No adapter is required. The only limitation is that some advanced features — such as charge port opening via the handle button — are exclusive to Tesla vehicles.
Do I need a separate Type B RCD with this charger?
Not necessarily for the charger itself. The Wall Connector Gen 3 has a built-in Type A RCD with 6 mA DC fault detection, which satisfies the protection requirement that previously mandated an expensive external Type B RCD. However, your installer must still assess the full installation under BS 7671 — depending on your supply type and consumer unit configuration, upstream RCD or SPD protection at the consumer unit may still be appropriate or required. Always follow your qualified electrician's recommendations.
Will I get 22 kW at home, or only 7 kW?
Almost all UK domestic properties are supplied on a single-phase 230 V connection, which limits the Wall Connector to a maximum of 7.4 kW at 32 A. The 22.1 kW output is only achievable on a three-phase 400 V supply — more common in commercial premises, some new-build estates, and certain rural properties. If you are unsure which supply type your property has, check with your Distribution Network Operator (DNO) or ask your electrician to verify before purchase. For most households, 7.4 kW is sufficient to fully charge an EV overnight with charge to spare.
What is PEN fault detection and why is it needed in the UK?
Most UK homes are connected to the grid via a TN-C-S (PME) earthing arrangement, where the protective earth and neutral conductors are combined in the distribution network. In the rare event of a PEN (Protective Earth and Neutral) conductor failure, exposed metalwork — including an EV chassis — could become live. BS 7671 Amendment 2 requires that EV chargers installed on TN-C-S supplies include protection against this scenario, typically via a PEN fault detection and isolation device (e.g. the Matt:e SPM), an isolating transformer, or a dedicated TT earth. Your qualified electrician will assess the requirement and fit the appropriate solution as part of the installation.
Can I schedule charging to use off-peak electricity tariffs?
Yes. Once connected to your home Wi-Fi via the Tesla app, you can schedule charging sessions to run during off-peak windows — for example, midnight to 5 am on tariffs like Octopus Go or British Gas Electric Drivers. The Tesla app allows departure time setting and charge limit control directly from your phone. For fully automated rate-hunting, the Wall Connector is also compatible with Octopus Intelligent Go, which integrates with the Tesla vehicle directly to automatically find and charge during the cheapest half-hour slots. This can reduce home charging costs significantly — potentially to under 8p/kWh compared to over 24p on standard rate.
What happens to charging if the power goes out?
If the power is interrupted mid-session, the Wall Connector will automatically resume charging within 1–3 minutes once power is restored. A solid blue LED on the faceplate indicates that the unit is communicating with the vehicle and preparing to resume. You can also press the button on the charge handle immediately after power is restored to resume charging without waiting. Group power management settings are preserved across power loss events.

Does the Tesla Wall Connector work with non-Tesla EVs?
Yes. The Gen 3 Wall Connector uses a standard Type 2 (IEC 62196) tethered cable, which plugs directly into the charge port of virtually every EV sold in the UK — including Volkswagen ID.3/ID.4, BMW iX, Hyundai Ioniq 5, Kia EV6, Nissan Leaf, Renault Zoe, Polestar 2, Mercedes EQA, Audi Q4 e-tron, and many more. No adapter is required. The only limitation is that some advanced features — such as charge port opening via the handle button — are exclusive to Tesla vehicles.
Do I need a separate Type B RCD with this charger?
Not necessarily for the charger itself. The Wall Connector Gen 3 has a built-in Type A RCD with 6 mA DC fault detection, which satisfies the protection requirement that previously mandated an expensive external Type B RCD. However, your installer must still assess the full installation under BS 7671 — depending on your supply type and consumer unit configuration, upstream RCD or SPD protection at the consumer unit may still be appropriate or required. Always follow your qualified electrician's recommendations.
Will I get 22 kW at home, or only 7 kW?
Almost all UK domestic properties are supplied on a single-phase 230 V connection, which limits the Wall Connector to a maximum of 7.4 kW at 32 A. The 22.1 kW output is only achievable on a three-phase 400 V supply — more common in commercial premises, some new-build estates, and certain rural properties. If you are unsure which supply type your property has, check with your Distribution Network Operator (DNO) or ask your electrician to verify before purchase. For most households, 7.4 kW is sufficient to fully charge an EV overnight with charge to spare.
What is PEN fault detection and why is it needed in the UK?
Most UK homes are connected to the grid via a TN-C-S (PME) earthing arrangement, where the protective earth and neutral conductors are combined in the distribution network. In the rare event of a PEN (Protective Earth and Neutral) conductor failure, exposed metalwork — including an EV chassis — could become live. BS 7671 Amendment 2 requires that EV chargers installed on TN-C-S supplies include protection against this scenario, typically via a PEN fault detection and isolation device (e.g. the Matt:e SPM), an isolating transformer, or a dedicated TT earth. Your qualified electrician will assess the requirement and fit the appropriate solution as part of the installation.
Can I schedule charging to use off-peak electricity tariffs?
Yes. Once connected to your home Wi-Fi via the Tesla app, you can schedule charging sessions to run during off-peak windows — for example, midnight to 5 am on tariffs like Octopus Go or British Gas Electric Drivers. The Tesla app allows departure time setting and charge limit control directly from your phone. For fully automated rate-hunting, the Wall Connector is also compatible with Octopus Intelligent Go, which integrates with the Tesla vehicle directly to automatically find and charge during the cheapest half-hour slots. This can reduce home charging costs significantly — potentially to under 8p/kWh compared to over 24p on standard rate.
What happens to charging if the power goes out?
If the power is interrupted mid-session, the Wall Connector will automatically resume charging within 1–3 minutes once power is restored. A solid blue LED on the faceplate indicates that the unit is communicating with the vehicle and preparing to resume. You can also press the button on the charge handle immediately after power is restored to resume charging without waiting. Group power management settings are preserved across power loss events.
