Plan the Location
IMPORTANT: While this charger can be installed as either a plug-in
or hardwired, we recommend hardwiring for optimal performance.
Before beginning work, check the site for appropriate mounting location and
electrical capacity.
1. Ensure the homeowner has chosen an installation location that allows
the charging cable to reach the car's charging port while still providing
slack. Mount the charging station on a surface that can support the full
weight of the charging station with the cord hanging from it. Follow the
steps below to mount on a surface using the supplied screws. Ensure
Wi-Fi signal is available.
Note: Outdoor installation requires hardwiring or an outdoor-rated,
weather-resistant electrical outlet.
WARNING: In areas with frequent thunderstorms, add surge
protection at the service panel. Ensure all power and ground
connections, especially those at the breaker and bus bar, are clean
and tight. Remove all oxide from all conductors and terminals before
connecting wiring.
2. Home Flex must be set to match the rating of the circuit as determined
by the available panel capacity.
CAUTION: Home Flex is a continuous load device. The circuit must
be rated for 125% of the maximum load.
Consult all applicable codes for breaker and wire sizing requirements. The
field-wiring terminal is rated to 105 °C (221 °F) and accepts a maximum of 16
mm2 (6AWG) wire. Home Flex supports the following amperages for circuit
capacity:

Table: Home Flex supports the following amperages for circuit
capacity
IMPORTANT: In Canada, a plug-in installation is only allowed with a
50 A circuit.
3. For plug-in installation, determine the plug type
purchased by the homeowner. It is either a NEMA
14-50 or 6-50 type plug.
4. For a hardwired installation, determine if the desired
circuit rating requires a hardwired circuit.
10chargepoint.com

5. Ensure the electrical panel supports a 240 V dedicated circuit with a
new, dedicated, non-GFCI two-pole circuit breaker, in accordance with
local codes and ordinances.
Note: If local codes require a GFCI breaker for plug-in installation,
ChargePoint recommends a hardwire installation. We do not
recommend using a GFCI breaker as the Home Flex has charging circuit
interrupting device (CCID) protection. Using a GFCI breaker in the panel
can cause nuisance tripping.
6. For plug-in installations, the outlet should
be located 0.45-0.66m (20-26in) from the
ground adjacent to the stud where the
charging station will be mounted.
Note: The input power cable is 0.45 m (18
in) long (as per the National Electric Code
for EV chargers). Ensure the outlet is
installed close enough to the stud for the
input power cable to plug in.
7. Follow all applicable codes and ordinances
and pull a permit for completing the
electrical work as required.
Wire the Circuit
1. Turn off the circuit breaker to the 240 V outlet.
WARNING: RISK OF SHOCK. Do not restore power to the
outlet until installation is complete. Failure to follow these
instructions could result in shock or electrocution.
2. Install a circuit:
lFor a 40 or 50 A plug-in installation, wire the circuit with the
appropriate 6-50 or 14-50 outlet. Install the outlet with the
ground facing up.
lFor a hardwired installation, provide a listed conduit with wiring
to the bottom or rear 19 mm (3/4 in) knockout for AC input. Seal
the unused knockout with the plug provided.
3. Affix the label with the appropriate rating to the circuit in the panel.
4. Ensure power is off to the circuit at the panel before proceeding.
