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.
Danger
{
Improper use of portable electric
vehicle charge cords may cause a
fire, electrical shock, or burns, and
may result in damage to property,
serious injury, or death.
.
Do not use extension cords,
multi-outlet power strips,
splitters, grounding adaptors,
surge protectors, or similar
devices.
.
Do not use an electrical outlet
that is worn or damaged,
or will not hold the plug
firmly in place.
.
Do not use an electrical outlet
that is not properly grounded.
.
