Features

Circuit Ratings

Use a single-phase circuit rated for 50A
single-phase to obtain the fastest charging.
Note: Tesla vehicles must be configured with
optional onboard charging equipment to
accept higher amperages. Contact Tesla if you
have questions about the onboard charging
capabilities of your 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 11). 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
14).

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.
