Important Information About
Portable Electric Vehicle Charging
.Charging an electric vehicle can
stress a building’s electrical
system more than a typical
household appliance. .
Before you plug in to any electrical
outlet, have a qualified electrician
inspect and verify the electrical
system (electrical outlet, wiring,
junctions, and protection devices)
for heavy-duty service at a 12 amp
continuous load.
. Electrical outlets may wear out
with normal usage or be damaged
over time, making them unsuitable
for electric vehicle charging.
. Check the electrical outlet/plug
while charging and discontinue
use if the electrical outlet/plug is
hot, then have the electrical outlet
serviced by a qualified electrician.
. When outdoors, plug into an
electrical outlet that is
weatherproof.
. Mount the charging cord to reduce
strain on the electrical outlet/plug.
