General NEMA (250V) Receptacle Home Installation Precautions
Porsche recommends home owners only install industrial quality electrical NEMA receptacles and have
the installation performed by qualified electricians in accordance with the National Electrical Code or
applicable local equivalents.

ENU 197/21
WMP2
For example, the following receptacles are recommended for their industrial quality and ability to handle
high current with minimal electrical resistance for long periods of time:
•
•
Hubbell HBL9450A = NEMA 14-50 Receptacle (4-wire)
Hubbell HBL9367 = NEMA 6-50 Receptacle (3-wire)
A 50-amp branch circuit should use minimum 6 AWG, 90°C-rated copper wire for conductors supplying
level 2 Porsche charging hardware plugged with a NEMA 14-50 or 6-50 supply cable. Receptacle
terminal screws must be tightened to manufacturer specifications. The use of ferrules on the supply
conductor wiring is recommended to further safeguard the circuit connection at the receptacle.
Caution
If the electrical receptacles/outlets are not of sufficient quality, higher temperatures can
occur in the receptacle when charging the vehicle using the supplied charging hardware (e.g.
Porsche Mobile Charger). This can result in thermal damage to the receptacle and associated
wiring. Low quality NEMA receptacle use or improper installation are not an indication of a
defect in the vehicle or Porsche charging hardware.
General Precautions on (125V) Supply Cable Use
The “domestic” (125V) supply cable is provided for emergency use only, and should not be used by
customers for daily home charging. Please discuss installation and use of a suitable 250V circuit with
all customers.
Information
Caution
The surface of the charger and associated equipment can become very hot under normal use. This is
normal and not an indication of a defect in the charger. Observe the operating instructions provided with
the charger, particularly the warnings and safety instructions.
When used, it is recommended to limit 125V charging to a maximum of approximately 12 hours. Charge
only to a minimum needed get to a nearest High-Power Charger (HPC) or DC Charger for recharging.
