POWER SUPPLY OPTIONS
For basic operation, Wall Connector requires an electrical connection to Line 1, Neutral, and Protective Earth
(PE) terminals. Connection to Line 2 and Line 3 terminals is supported for some grid types.
CAUTION: Wall Connector supports 230 V L-N (+/- 10%). Mis-wiring the neutral terminal with >264V
to PE can damage Wall connector
Wall Connector can operate on a three-phase power supply or a single-phase power supply.
Table 1. Most Common Installation Option
Wiring Configuration Option for Five Wires: Line 1, Line 2, Line 3, Neutral, PE
Grid type options:
• 400 V 3-phase wye
CAUTION: Double check N
connection is 230 V L to N at
terminals of wirebox before
energizing.
NOTE: Blue is used as the IEC standard for neutral. Some markets may use other colors to symbolize
neutral and line conductors.

wirebox.
NOTE: The conductor with
lowest voltage to
Protective Earth (PE)
should be connected to
the Neutral terminal.
*When connecting to a 230 V delta no
neutral grid, land one of the line
connections in the neutral terminal of
the wirebox.
CAUTION: Double check N

CIRCUIT BREAKER RATING / MAXIMUM OUTPUT
Power Output
For the best charge rate, install a circuit breaker to match the grid type and desired current output. Wall
Connector features built-in RCD Type A + DC 6mA.
Maximum current output (amps) can be programmed by the installer as part of the commissioning process.
Any amperage between 6 A and 32 A can be selected. Estimate power output for various grid connections
below:
NOTE: Some Tesla vehicles may draw less current than the max output of Wall Connector. Actual
charging rate depends on Wall Connector output and onboard charger in the vehicle. See Tesla
website for vehicle specifications.

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
