HIGH POWER WALL CONNECTOR
6
230V ABOVE GROUND
For most branch circuits of 100A, use 3 AWG (26.7 mm
2
), 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 10.
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, refer to 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.
WARNINGS:
The High Power Wall Connector is a single-phase device. Do not connect all 3 phases
of a 3-phase feed.
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.
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: Follow local electrical codes when installing the grounding stake.
