Features

Circuit Ratings

Use a single-phase circuit breaker rated for
50A single phase to obtain the highest power
output.
In certain installation locations, this level of
power isn't readily available. Therefore, the
Wall Connector has an automatic load
management feature that allows the output
current to be adjusted to any circuit breaker
ranging from 15A to 50A (refer to Set the
Operating Current on page 18).
Note: Actual amperage draw will depend on
the on-board charger of the vehicle. Contact
Tesla if you have questions about the on-
board charger of a specific vehicle.

Self-Monitoring and Recovery

The Wall Connector has a ground monitoring
circuit that continuously checks for the
presence of a safe ground connection and
automatically recovers from faults. Manual
testing and resetting is not required.
Temporary problems such as ground faults or
utility power surges are overcome
automatically. If a residual current fault occurs
that interrupts charging, the Wall Connector
automatically tries to clear the fault and re-
attempt charging.
If the problem is immediately sensed a second
time, the Wall Connector waits 15 minutes
before trying to charge. This process repeats 4
times and if all attempts are unsuccessful,
power is removed and no further attempts are
made. In this case, you will see a red error light
on the front panel (refer to Troubleshooting
on page 21). It is recommended that when
you see a red error light, you power off the
Wall Connector by switching off the upstream
circuit breaker, and then power it back on
again.
The Wall Connector can alternatively be reset
when a red error light is encountered using
the RESET button (refer to Reset on page
24).

Power Outages

If a power outage occurs, the Wall Connector
automatically resumes charging when power
is restored. If the charging cable is plugged
into the vehicle when power is restored, the
lights blink and the unit does not energize the
charging cable for approximately 15 seconds
to three minutes. This prevents the utility grid
from experiencing a large surge when power is
restored and allows vehicles to begin drawing
current at random times, rather than all at
once.

Load Sharing

Up to 4 Wall Connectors can be wired to a
single circuit, and with built-in automatic load
management, vehicle owners can easily
charge multiple vehicles at home (refer to
Appendix B: Optional Connection for Load
Sharing on page 27).
