Planning Your Installation; Minimum Requirements; Service Wiring; 400V Three-Phase With Neutral - Tesla WALL CONNECTOR Installation Manual

Minimum Requirements

Installation of the Wall Connector requires that
you:
• Calculate the existing electrical load to
determine the maximum operating
current.
• Calculate the distance to ensure minimal
voltage drop.
• Obtain any necessary permits from the
local authority that has jurisdiction and
confirm that the follow-up inspection has
been scheduled by an electrician after the
installation is complete.
• Use only copper conductors.
• Use conductors that are sized in
accordance with local wiring regulations.
The selected cable must be able to sustain
periods of constant load of up to 40A.
• Use protective devices. The circuit
protection device chosen must
incorporate a suitable residual-current
device (RCD) and overcurrent protection
in relation to the electrical load selected.
Note: Consult with an electrician to ensure
that the installation meets local regulations.

Service Wiring

400V Three-Phase With Neutral

For three-phase use of a Wye-connected
secondary, all three phases (L1, L2, and L3)
and neutral should be connected. Each phase
voltage should measure 230V to neutral.

230V Single-Phase With Neutral

For single-phase use of a Wye-connected
secondary, only a single-phase (L1) and neutral
should be connected. This phase voltage
should measure 230V between line and
neutral.
Warning: The Wall Connector in this
configuration operates only from a single-
phase (L1). Do not connect the remaining
phases (L2 and L3).
Warning: Before installing the 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 an
electrician, or contact Tesla for assistance.
Note: Consult with your local electrician or
refer to your local code for proper wire sizing
appropriate for the currents in your Wall
Connector.
