Receptacle safety instructions (240 V plug-type EVSE)
An EV Supply Equipment (EVSE) draws substantially more power than any average home load. For plug-type EVSE units,
the provided 14-50R or 6-50R receptacle shall be installed by a qualied electrician per local codes and standards and in
accordance with the manufacturer's instructions. If you require an additional or replacement receptacle, please contact
Enphase Support for assistance.
NOTE: Installation of the receptacle shall be in accordance with local codes and the instructions provided with the
receptacle by a qualied electrician.
WARNING: Improper installation of receptacles may have an increased risk of overheating and may lead to re hazards.
It is also highly recommended that a qualied electrician inspects the premise wire connections on the back of a pre-existing
NEMA outlet before using it. Wire connection points behind the receptacle may become loose or oxidized if they were installed
many years ago and may cause the outlet to fail. Ensure that the receptacles are free of any physical damage or defects prior
to the installation of the EVSE.
If you believe the provided receptacle to be defective, please contact Enphase Support at 877-797-4743.
