CIRCUIT BREAKER RATING / MAXIMUM OUTPUT
Branch Circuit Conductors and Earth Wire
• Refer to local electrical code to select correct conductors and earth wire size that are suitable for the
chosen circuit breaker.
• Wall Connector wirebox terminals can accept stranded wire sized between 4 mm2 to 25 mm2, or solid
wire 1.5 mm2 to 25 mm2. Installer is responsible for selecting a wire size that will be compliant with
local code, possibly taking into account amperage, distance and other site conditions.
NOTE: If using stranded wiring smaller than 4 mm2, use a correctly sized ferrule so it can be
securely terminated.
• For sites with multiple Wall Connectors, each Wall Connector must have its own branch circuit and
dedicated circuit breaker.
• For outdoor installations, use watertight fittings when securing feeder wires to the wirebox.
• For this installation guide, IEC standard colors are used for L1, L2, L3, Neutral, and PE. Some regions
may use other standardized colors.
Earth Connections
Wall Connector must have an earth path back to the main equipment earthing point on site. Without a
proper earth connection, the Wall Connector will not charge a vehicle during an earth assurance test.
Equipment-earth conductor must be run with the circuit conductors and connected to the equipment-earth
terminal in the wirebox. Install a earth wire sized according to local electrical code.
NOTE: To support TT and IT grids, earth assurance can be disabled as part of the commissioning
process. Earth assurance must always be enabled for TN grids.
Additional requirements apply to UK properties fed from a TN-C-S supply. In most scenarios, these
properties will require an external device which provides PEN fault detection and isolation in accordance
with BS 7671. It is the responsibility of the installer to ensure that the requirements of BS7671 are met please refer to Tesla's application note at the end of this manual that discusses this topic in more detail.
NOTE: The use of an dedicated earth rod for the EVSE will not generally be a practical solution to
meet the BS 7671 requirements

12Gen 3 Wall Connector Manual
FEATURES
Connectivity
Wall Connector is equipped with Wi-Fi to communicate with local site routers, vehicles, mobile devices,
other Wall Connectors, and other Tesla products.
Hosted Access Point
Wall Connector hosts a WPA2 password-secured, 2.4 GHz, 802.11 Wi-Fi access point network to facilitate
commissioning and connecting to other devices.
A unique SSID Wi-Fi network name and WPA2 password for connecting to the Wall Connector are printed
on a label at the rear of the main unit, as well as on the front cover of the Quickstart Guide included in the
box.
Local Network
Connecting Wall Connector to a local Wi-Fi network enables it to receive over-the-air firmware updates,
remote diagnostics access, and usage data tracking capability. A Wi-Fi connection is required for sites that
utilize authentication, billing, and other property management features.
NOTE: Some features will be added over time.
Wall Connector only supports WPA2/3-secured, 2.4 GHz, 802.11 infrastructure mode networks.
13Gen 3 Wall Connector Manual
FEATURES
NOTE: Hidden networks are supported.
NOTE: WPA enterprise will be supported in a future firmware update.
NOTE: Property management features will be enabled via future firmware updates.
Residual Current Device (RCD)
Wall Connector features built-in RCD Type A + DC 6mA. The benefit of this protection is that RCD Type B
are not required when installing Gen 3 Wall Connectors, consult local regulations on the type of breaker
required.
AC earth fault interruption automatically detects an AC current mismatch between power delivery
conductors that would indicate that current is flowing through the earth conductor. AC fault protection will
trip at 20 mA.
DC earth fault interruption automatically detects DC leakage through earth. DC fault protection will trip at 6
mA.
User interaction such as pressing the cable button or unplugging from vehicle is required to clear this fault. If
fault continues, consult with an electrician to review power supply.
Ground Monitor Interrupter
The ground monitor interrupter allows the installer to select dierent early monitor options. Wall Connector
continuously checks for the presence of a safe earth connection and automatically recovers from faults.
Earth assurance operates by injecting a small amount of current into the earth conductor in order to
measure the impedance between line and earth. If high impedance is detected, the Wall Connector will lock
out charging and display a error code of two (2) red blinks. See Error Codes on page 32 for a full list of
error codes.
For earth assurance to operate on TN grids, one leg of the distribution transformer must be earth-bonded
(Neutral). Earth bond should only occur at one location in a site's electrical system.
Wall Connector earth assurance may be adjusted in countries with TT or IT grid configurations.
The Earth Monitor Interrupter feature monitors the Wall Connector earth connection. Select the correct
option based on the installation's earthing system and earth impedance.
Depending on country, three options are available:
• Enable: Earth connection will be monitored and a high detected earth resistance will disable the Wall
Connector. This is the preferred setting to provide protection, and should be selected where earth
connection is expected to be strong (as in the case on TN networks and most TT networks), and
where required by regulation.
• Disabled: Earth connection will not be monitored. This should be selected where the earth connection
is not made (as is the case for IT networks), or where the current induced by this check would be
problematic (as is the case on some TT networks with sensitive residual-current devices).
NOTE: Earth Monitoring is always enabled for installations in North America.
Temporary problems such as earth faults or utility power surges are resolved automatically.
14Gen 3 Wall Connector Manual
FEATURES
Power Outages
If there is a power outage while Wall Connector is charging a vehicle, charging will automatically resume
within 1 to 3 minutes after power restoration. The Wall Connector will display a solid blue light on the
faceplate to indicate that it is communicating with the vehicle and waiting to resume charging. Alternatively,
pressing the button on the charge handle after power restoration will cause Wall Connector to resume
charging immediately.
Firmware Updates
Firmware updates will be automatically applied to the Wall Connector to improve the user experience and
introduce new features. Connect Wall Connector to Wi-Fi for access to the most recent firmware update. See
Commissioning Procedure on page 29.
Thermal Monitoring
Wall Connector actively monitors temperatures in multiple locations while charging to ensure stability of the
charge session. Temperature sensors are located at the relays, microcontroller, charge handle, and rear of the
main unit to monitor the temperature of the terminals in the wirebox.
In warmer conditions, Wall Connector may reduce current and charge speed to protect itself. When this
happens, the light bar on the faceplate will continue to display the “streaming green” and a blink code of
three red flashes to indicate that charging has been reduced due to high temperatures. If heat continues to
rise, Wall Connector will stop charging and display a blink code of three red flashes.
NOTE: See Error Codes on page 32 for full list of error codes.
For optimal performance, install Wall Connectors in areas where ambient temperature will remain below
50˚C (122˚F). In rare circumstances, Wall Connector may begin reducing amperage at 35˚C (95˚F) ambient
temperatures. Adjustments to amperage are automatic and do not require user input; Wall Connector will
return to starting current when temperatures are reduced.

and supplied Wall Connector that occur under normal personal use for a period of 48 months, or a period of
12 months for normal commercial use*, and a Tesla manufactured and supplied Mobile Connector or charging
adapter that occur under normal use for a period of 12 months, starting from the date of invoice to the
customer for any charging equipment. Any Tesla manufactured and supplied connector or adapter included
in the initial purchase and delivery of a Tesla vehicle by Tesla is covered under the Basic Vehicle Limited
Warranty section of the New Vehicle Limited Warranty for 4 years or 50,000 miles (80,000 km), whichever
comes first, subject to the terms and conditions of the New Vehicle Limited Warranty.
*For warranty claims specific to Wall Connectors, “commercial use” means Wall Connectors used for
purposes other than charging at a residential single family home for daily personal use, which includes, but is
not limited to, charging at hotels, oces, parking lots and complexes (including apartment, condominiums
and other multi-family or unit dwellings), and retail and other locations that allow (including by being listed
online or publicly) for pay-for-use charging, or are located where users other than the owner could
reasonably obtain access to the Wall Connector.
This Charging Equipment Limited Warranty does not cover any damage or malfunction directly or indirectly
caused by, due to, or resulting from, normal wear or deterioration, abuse, misuse, negligence, accident, lack
of or improper installation, use, maintenance, storage or transport, including, but not limited to, any of the
following:
Failure to follow the instructions, operation, maintenance and warnings published in the documentation
supplied with your Tesla connector or adapter;
External factors, including but not limited to, objects striking the Tesla connector or adapter, faulty or
damaged electrical wiring or connections, external electrical faults, junction boxes, circuit breakers,
receptacles or power outlets, the environment or an act of God, including, but not limited to, fire,
earthquake, water, lightning and other environmental conditions;
General appearance or damage to paint, including chips, scratches, dents and cracks;
Failure to contact Tesla upon discovery of a defect covered by this Charging Equipment Limited Warranty;
Any repair, alteration or modification to the Tesla connector or adapter or any part, or the installation or use
of any parts or accessories, made by a person or facility not authorized or certified to do so; and
Lack of or improper installation, repair or maintenance, including use of non-genuine Tesla accessories or
parts.
Although Tesla does not require you to perform all maintenance, service or repairs at a Tesla Service Center
or Tesla authorized repair facility, this Charging Equipment Limited Warranty may be voided, or coverage
may be excluded, due to lack of or improper maintenance, service or repairs. Tesla Service Centers and Tesla
authorized repair facilities have special training, expertise, tools and supplies with respect to Tesla
connectors and adapters and, in certain cases, may employ the only persons, or be the only facilities
authorized or certified to work on Tesla connectors and adapters. Tesla strongly recommends that you have
all maintenance, service and repairs done at a Tesla Service Center or Tesla authorized repair facility in order
to avoid voiding, or having coverage excluded under, this Charging Equipment Limited Warranty.

LIMITS OF LIABILITY
This Charging Equipment Limited Warranty is the only express warranty made in connection with your Tesla
connector or adapter. Implied and express warranties and conditions arising under applicable local laws,
federal statute or otherwise, in law or in equity, if any, including, but not limited to, implied warranties and
conditions of merchantability or merchantable quality, fitness for a particular purpose, durability, or those
arising by a course of dealing or usage of trade, or any warranties against latent or hidden defects, are
disclaimed to the fullest extent allowable by your local law, or limited in duration to the term of this Charging
Equipment Limited Warranty. To the fullest extent allowable by your local law, the performance of necessary
repairs and/or replacement of new, reconditioned, or remanufactured parts by Tesla for the covered defects
is the exclusive remedy under this Charging Equipment Limited Warranty or any implied warranties. To the
maximum extent permissible under your local law, liability is limited to the reasonable price for repair or
replacement of the applicable Tesla connector or adapter, not to exceed the manufacturer’s suggested retail
price. Replacement may be made with parts of like kind and quality, including non-original manufacturer’s
parts, or reconditioned or remanufactured parts, as necessary. This Charging Equipment Limited Warranty
covers only parts and factory labor necessary to repair but does not include any on-site labor costs related
to un-installing, reinstalling or removing the repaired or replacement charging equipment. Parts repaired or
replaced, including replacement of a Tesla connector or adapter, under this Charging Equipment Limited
Warranty are covered only until the applicable warranty period of this Charging Equipment Limited
Warranty ends, or as otherwise provided by applicable law. Under no circumstances will the original
warranty period be extended as a result of your Tesla connector or adapter being repaired or replaced.
Tesla shall not be liable for any defects under this Charging Equipment Limited Warranty that exceed the fair
market value of the applicable Tesla connector or adapter at the time immediately preceding the discovery
of the defect. In addition, the sum of all benefits payable under this Charging Equipment Limited Warranty
shall not exceed the price you paid for the applicable Tesla connector or adapter.
Tesla does not authorize any person or entity to create for it any other obligations or liability in connection
with this Charging Equipment Limited Warranty. Subject to local laws and regulations, the decision of
whether to repair or replace a part or to use a new, reconditioned or remanufactured part will be made by
Tesla, in its sole discretion. Tesla may occasionally oer to pay some or all of the cost of certain repairs that
are not covered by this Charging Equipment Limited Warranty, either for specific models or on an ad hoc,
case-by-case basis. Tesla reserves the right to do the above at any time without incurring any obligation to
make a similar payment to other Tesla charging equipment owners.
To the maximum extent permissible under local law, Tesla hereby disclaims any and all indirect, incidental,
special and consequential damages arising out of, or relating to, the Tesla connector or adapter, including,
but not limited to, transportation to and from a Tesla Authorized Service Center, loss of the Tesla connector
or adapter, loss of vehicle value, loss of time, loss of income, loss of use, loss of personal or commercial
property, inconvenience or aggravation, emotional distress or harm, commercial loss (including but not
limited to lost profits or earnings), towing charges, bus fares, vehicle rental, service call charges, gasoline
expenses, lodging expenses, damage to tow vehicle, and incidental charges such as telephone calls, facsimile
transmissions, and mailing expenses.
The above limitations and exclusions shall apply whether your claim is in contract, tort (including negligence
and gross negligence), breach of warranty or condition, misrepresentation (whether negligent or otherwise),
or otherwise at law or in equity, even if Tesla is advised of the possibility of such damages or such damages
are reasonably foreseeable.
Nothing in this Charging Equipment Limited Warranty shall exclude, or in any way limit, Tesla’s liability for
death or personal injury solely and directly caused by Tesla’s negligence, or that of its employees, agents or
sub-contractors (as applicable), fraud or fraudulent misrepresentation, or any other liability to the extent the
same is proven in a court of competent jurisdiction in a final nonappealable judgment and may not be
excluded or limited as a matter of local law.
