Conduit
The outer diameter of conduit or armored cable must not exceed the sizes called out in the conduit
layout drawing below. Conduit stub-ups cannot extend higher than 76.2 mm (3 in) above the
surface of the concrete pad.
In regions that do not use conduit, armored cable may be laid in the same configuration to conform
to the wire placement as shown in the section, “The Express 250 Concrete Mounting Template
(page 27)”. Ensure a length of at least 61 cm (2 ft) is left free above grade at each end to allow the
wiring to reach the charging station AC terminals.
a. Shunt trip conduit: 19.1 mm (3/4 in trade size)
b. AC conduit: 50.8 mm (2 in trade size)
c. Anchor bolts
d. Paired installations only: Ethernet conduit: 19.1 mm (3/4 in trade size)
e. Paired installations only: DC conduit: 76.2 mm (3 in trade size)
f. Concrete surface
g. Concrete Mounting Template (embedded in concrete)
Note: Ensure no bell ends are left on any conduit after all wires are pulled. Bell ends can interfere
with station placement.
Note: Depth of conduit or armored cable may vary by site. The image above does not dictate
conduit depth, as long as the stub-ups are vertical and placed correctly.
