NOTE: External disconnect switches are neither required nor recommended.
NOTE: Circuit breaker size is programmed during the commissioning process. See Commissioning
Procedure on page 28 for details.
NOTE: Some Tesla vehicles may draw less current than the max output. Actual charging rate depends
on Wall Connector output and onboard charger in the vehicle.
Branch Circuit Conductors and Ground Wire
• If installing for less than maximum power, refer to local electrical code to select correct conductors
and ground wire size that are suitable for the chosen circuit breaker.
• If installing for maximum power, use minimum 6 AWG, 90° C-rated copper wire for conductors.
NOTE: Upsize conductors if necessary.
• For sites with multiple Wall Connectors, each Wall Connector must have its own branch circuit with L1,
L2/N, and Ground.
• COPPER WIRE TERMINATIONS ONLY for landing in Wall Connector wirebox terminals. Conductors
can be stranded or solid.
• Hardwire branch circuits to disconnects or circuit breakers. Do NOT install cord-and-plug type
connections.
• For outdoor installations, use watertight fittings when securing feeder wires to the wirebox.
PRODUCT OVERVIEW

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.
Wall Connector only supports WPA2/3-secured, 2.4 GHz, 802.11 infrastructure mode networks.
NOTE: Networks that are not password protected are not supported. The Wall Connector will not
display non-password protected networks in the options list.Open networks without a password are
not supported and will not be recognized by the Wall Connector.
NOTE: WPA enterprise will be supported in a future firmware update.
PRODUCT OVERVIEW
10Gen 3 Wall Connector Manual
NOTE: Property management features will be enabled via future firmware updates.
PRODUCT OVERVIEW
11Gen 3 Wall Connector Manual
Ground Fault Circuit Interruption
Integrated ground fault circuit interruption (GFCI) protection automatically detects a current mismatch
between power delivery conductors that would indicate that current is flowing through the ground (PE)
conductor.
If a ground fault occurs after 10 seconds of charging, Wall Connector will wait 15 minutes before
automatically re-attempting to charge. Up to four attempts to charge will be made before user interaction is
required.
If a residual current fault occurs within 10 seconds of charging, Wall Connector will lock out and user
interaction is required to restore charging functionality.
Recommended interaction includes pressing the button on the charging handle, or removing the charging
handle from the vehicle and reinserting it. If this does not resolve the issue, look for a ground fault issue such
as water ingress.
Ground Assurance
Wall Connector continuously checks for the presence of a safe ground connection and automatically
recovers from faults.
Grounded assurance operates by injecting a small amount of current into the ground
conductor in order to measure the impedance between line and ground. If high impedance is detected, the
Wall Connector will lock out charging and display a fault code of two (2) red blinks. See Fault Codes on page
38 for a full list of fault codes.
For ground assurance to operate on TN grids, one leg of the distribution transformer must be ground-
bonded (Neutral). Ground bond should only occur at one location in a site's electrical system.
Wall Connector ground assurance may be adjusted in countries with TT or IT grid configurations and can be
disabled in the commissioning procedure.
The Ground Monitor Interrupter feature monitors the Wall Connector ground connection. Select the correct
option based on the installation's earthing system and earth impedance.
Depending on country, three options are available:
• Enable: Ground connection will be monitored and a high detected ground resistance will disable the
Wall Connector. This is the preferred setting to provide protection, and should be selected where
ground connection is expected to be strong (as in the case on TN networks and most TT networks),
and where required by regulation.
• Monitor: Ground connection will be monitored but a high detected ground resistance will not disable
the Wall Connector. This should be selected if the ground monitoring check yields false positives and
ground impedance cannot be improved (as is the case in some TT networks).
• Disabled: Ground connection will not be monitored. This should be selected where the ground
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: Ground Monitoring is always enabled for installations in North America.
Temporary problems such as ground faults or utility power surges are resolved automatically.
PRODUCT OVERVIEW
12Gen 3 Wall Connector Manual
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 Fault Codes on page 38 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.
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 28.
Tesla vehicles can provide firmware updates to Wall Connectors.

POWER SHARING
Power Sharing Overview
The firmware-based power sharing feature enables up to 6 Wall Connectors installed at the same site to
intelligently share the site's total available power via unit-to-unit Wi-Fi. This minimizes the need for many
residential and commercial applications to have specific electrical upgrades for concurrent multi-vehicle
charging.
During the commissioning process,
• Wall Connectors are allocated to individual branch circuits (each up to 60 amps)
• Total power is allocated to the group of linked Wall Connectors
NOTE: For instructions to commission Wall Connectors in a power sharing network, see Gen 3 Wall
Connector Power Sharing.
Total current output of Wall Connectors that share power will never exceed the site's total allocated power.
1. AC feed (service panel)
2. Power sharing via Wi-Fi communication
31Gen 3 Wall Connector Manual
Breaker and Branch Circuit Setup
Power sharing circuits may be installed in an electrical panel that supports other loads. If space is limited or
the main power supply is far from the Wall Connectors, installing a dedicated load center may be prudent.
See below for examples of Wall Connector power sharing diagrams (one with sub-panel and one without).
Each individual Wall Connector in below examples is capable of providing 48 amps when it is the only one in
use. As more Wall Connectors begin plugging into vehicles, the system will automatically distribute power
based on the total power allocated to the site.

32Gen 3 Wall Connector Manual
Considerations for Power Sharing
Wall Connector power sharing is achieved wirelessly.
For optimal performance, Wall Connectors within a power sharing network should be installed within view of
each other whenever possible.
NOTE: Line of sight is recommended but not required. Wireless communication is capable of reaching
around concrete corners but network range may degrade as a result.
Avoid placing Wall Connectors on opposite sides of concrete, masonry, metal studs, and other physical
obstructions that would impede Wi-Fi signal strength.
NOTE: If a mobile device is able to connect to the Leader Wall Connector Wi-Fi, it is a good indication
that the Follower Wall Connector will also be able to connect.
Calculating Power Sharing Requirements for Existing Systems
To calculate power supply requirements per number of Wall Connectors for existing electrical systems, use
the following equation:
Available continuous
amperage:
Number of Wall Connectors: Max amperage output per Wall Connector
when 100% utilized:
_____________________ ÷ ________________________ = ________________________
NOTE: Maximum number of Wall Connectors for power sharing is 6.
NOTE: When calculating maximum amperage per Wall Connector, 100% utilization must be greater
than 6 amps for power sharing operation. If maximum amperage is greater than 48 amps, power
sharing is not necessary.
For large scale sites, consider expected parking time in relation to a 100% utilization rate.
Expected Park Time (hours) Examples Recommended Amperage per wall
Connector at 100% Utilization
6+ (long term) Long term parking, overnight
parking
12+ amps
3-5 (medium term) Workplace, hospitality 24+ amps
1-2 (short term) Shopping and dining 32+ amps
NOTE: 100% utilization represents the worst case scenario for charging speeds, where the least
amount of power would be available for each individual vehicle. In most situations, not all Wall
Connectors would be actively charging a vehicle, which enables faster charging for the remaining
vehicles.
POWER SHARING
33Gen 3 Wall Connector Manual
Power Sharing Commissioning Procedure
1. Identify and configure the wall connector.
One Wall Connector will be the designated leader and provide the configuration and controls for all
followers. Install and configure the leader first. Follow the process in the Commissioning Procedure on
page 28 to connect and configure the leader.
2. Add up to five additional followers from the lead Wall Connector.
Click on the power sharing card in the commissioning interface and add additional Wall Connectors to
form a power sharing network by wirelessly pairing them to the leader.
NOTE: When pairing followers, the leader will restart, and you will lose Wi-Fi connection. If your
connection does not automatically return, ensure you are still connected to the leader's Wi-Fi
connection and refresh the page.
3. Set network limits.
Once all followers have been added, set the network limit. This is the total current that will be
intelligently distributed between all devices that have vehicles charging.
The minimum current limit is 6 amps per Wall Connector. A six-unit network will have a minimum limit
of 36 amps.
The maximum network limit is the sum of the nameplate ratings of all units in the network, minus one
amp. A six-unit network of single-phase Wall Connectors can have a maximum network limit of 287
amps. If 288 amps or more electrical service is available in this scenario, then all units can charge at full
power and power sharing is not needed. Chat with your electrician for further understanding of the
maximum network limit.
POWER SHARING
34Gen 3 Wall Connector Manual
NOTE: In the event that your leader and followers have dierent circuit breakers, you have to
individually connect to each of the followers on dierent breakers via the Wi-Fi broadcast, and
then set the correct breaker limit.
NOTE: For example, in a four Wall Connector network with two 60 amp breakers, one 50 amp
breaker and one 20 amp breaker where the leader has a 60 amp breaker, individually connect
to the Wall Connectors with 50 amp and 20 amp breakers and set their current limit in the
commissioning interface using the Commissioning Procedure on page 28.
4. Enable power sharing network.
Once your power sharing network is fully established (followers paired and network limit set), you will
have the ability to enable the network.
NOTE: No units in the network will be able to charge the connected vehicles if the power
sharing has not been enabled.
