Service Wiring - Europe

230V ABOVE GROUND
WARNING: The High Power Wall
Connector is a single-phase device. Do
not connect all 3 phases of a 3-phase feed.
WARNING: Before installing the High
Power Wall Connector, identify the type
of utility service connection available on site. If
you are unsure about the type of connection
available at the service panel, consult the local
utility company, or contact Tesla for
assistance.
CAUTION: The line connection must
measure 230V RMS to neutral. earth
must also be connected to the High Power
Wall Connector.
For most branch circuits of 100A, use 3 AWG
2
(26.7 mm ), 75°C (167°F) copper wire. For
installations less than 100A, use conductors
that are sized according to local electrical
codes. Ground wiring can be a maximum of 4
AWG. If your ground wiring does not fit into
the bus, use a wire nut or other suitable
connection method.
Run 25 mm (1") conduit on the left side of a
wall stud. The conduit fits into the opening on
either the back or the left side of the High
Power Wall Connector as described on page 11.
The service connections described below are
primarily used in Europe and Australia
(sometimes known as "TT Power Grid"). For
service connections used in North America,
see page 4.
When connecting the line and neutral wires,
care must be taken that the service
transformer secondary connection is definitely
known, and the wires from the main circuit
breaker panel are correctly connected and
labeled. The illustrations provided show the
most commonly used wiring format in Europe.
NOTE: The line, neutral, and earth outputs
labeled on the illustrations correspond to the
inputs on the High Power Wall Connector.
Ground (Earth) Connection
Always connect the neutral line at the service
panel to earth. Ground fault protection is not
possible unless the neutral line is connected to
earth.
6
If an earth connection is not available, you
must install a grounding stake nearby. The
grounding stake must be connected to the
ground bar in the main breaker panel, and
neutral connected to earth at that point.
WARNING: Follow local electrical codes
when installing the grounding stake.
