WARNING: The Home Connector is a
single-phase device.

The following types of service connection
are primarily used in Europe and Australia
(sometimes known as “TT Power Grid”).
IMPORTANT! Before commencing on the
installation of the Home Connector it is
important you correctly 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 Motors for assistance.
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 illustration
provided on this page shows the most
commonly used wiring format in Europe.
Note:
The LINE, NEUTRAL, and EARTH
outputs on the following illustration
correspond to the inputs on the Home
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.
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: Always follow local
electrical codes when installing the
grounding stake.
