ELECTRICAL REQUIREMENTS FOR BATTERY CHARGING
CAUTION: The AC electrical connection must
have a grounded, dedicated service-main. No
other loads shall be connected to the same
circuit. Use of a non-dedicated circuit could
exceed the current rating of the circuit breaker
and cause it to trip or open.

WARNING: The EVSE must be installed
by a licensed electrician in accordance
with all national and local electrical codes,
ordinances, requirements and all authorities
having jurisdiction.
The conduit may extend up to 24 in. (61 cm) from
ground level. The wiring should extend 66 in. from
the base mounting of the bollard. A sweep is used to
direct the circuit from the conduit to the electric circuit
from the service panel. The three types of acceptable
wire runs are:
•
THWN rigid metal Schedule 40 or 80 conduit,
buried 6 in. (15 cm) below ground level, or per
local electrical code.
•
THWN nonmetallic Schedule 40 or 80 conduit,
buried 18 in. (46 cm) below ground level, or
per local electrical code.
•
UF burial wire (ground solid), buried 24 in. (61
cm) below ground level, or per local electrical
code.
•
THHN, THWN, or THWN-2 wires are recom-
mended to allow for proper space requirements
inside the 1/2 in. flexible conduit required in-
side the bollard.
