INSTALLATION

WARNING: TO AVOID FIRE, SHOCK, OR DEATH, TURN OFF
POWER SUPPLYING THIS EQUIPMENT AND CONFIRM POWER IS
OFF before installing, removing, or servicing this equipment.

Step 1: Enclosure Knockouts

NOTE: Before removing any knockouts from the enclosure, consult
the local electrical code to determine the knockout requirements.
a. To remove knockouts (A), first strike the center of knockout.
b. Pry each ring (B) up, one at a time, and grip both ends with a
pair of pliers.
c. Use the pliers to bend the rings (B), until they disconnect
from the enclosure (fig. 1).
NOTE: When using the service entrance compartment cover (C),
utilize knockouts that will allow access to the service entrance
compartment. Avoid the entrance of phase wires (H), neutral (I),
and ground (J) conductors outside of the compartment area, to
prevent interference between them and the cover.

Step 2: Enclosure Mounting

Surface Mounting

NOTE: Leviton ® load centers can be inverted for bottom feed applications.
a. Remove the service entrance compartment cover (C) by unscrewing
the two (x2) screws (O) securing it to the enclosure (fig. 2).
NOTE: The service entrance compartment cover (C) is not
required for main lug load center enclosures.
b. Keyholes (D) at the top and bottom of the enclosure are
provided to assist in the alignment and leveling of the
enclosure (fig. 3).
c. Temporary screws or nails (not provided) should be used in
these keyholes during alignment and leveling.
d. Four (x4) mounting holes (E) have been precut in the back of
the enclosure for ease of installation (fig. 3).
e. Use screws or nails (not provided) in these four (x4)
mounting holes (E) to secure the enclosure to the wall.
f. Remove the temporary screws or nails that were used to align
and level the enclosure through the keyholes (D).

Flush Mounting

NOTE: Leviton load centers can be inverted for bottom feed applications.
a. Remove the service entrance compartment cover (C) by unscrewing
the two (x2) screws (O) securing it to the enclosure (fig. 2).
NOTE: The service entrance compartment cover (C) is not
required for main lug load center enclosures.
b. Four (x4) mounting slots (F) have been precut on the side of
the enclosure for installation between studs.
c. Pierce the foil tape (G) on the side of the enclosure, with a
mounting screw or nail.
d. If using 1/2 inch sheetrock, align the embossed (1/2) line with
the front of the stud to achieve optimal flush mounting.
e. Use the mounting slots (F) on both sides of the enclosure to
mount the enclosure with screws or nails (not provided) (fig. 4).

Step 3: Phase, Neutral, and Ground Conductors

WARNING: Use ONLY approved fittings and clamps to avoid damage to wires.
a. Bring the phase wires (H), neutral, (I) and ground (J) conductors into the enclosure through the predetermined knockouts.
b. Determine whether or not the application requires the use of a main circuit breaker (K) (fig. 5), or if main lugs (L) (fig. 6) can be used based on the local electrical codes.
c. Connect the phase wires (H), neutral (I), and ground (J) conductors to appropriate terminals and torque to spec in the terminations table (fig. 5 or 6).
d. If installing with a main circuit breaker (K), also install the two (x2) terminal covers (M) that have been provided (fig. 7).
e. When installing this enclosure as the service entrance, the bonding strap (N) MUST remain installed (fig. 8).
f. When installing this enclosure as a sub panel, REMOVE the bonding strap (N) by unscrewing the two (x2) mounting screws (fig. 9). With the bonding strap removed, ground
conductors must be terminated on the ground bar, and neutral conductors must be terminated on the neutral bar.
CAUTION: If the load center has been installed with a main breaker continue with steps g and h. Steps g and h do not apply to main lug load center enclosures.
g. Install the service entrance compartment cover (C) by placing the top edge under the enclosure flange (P) (fig. 10).
h. Align cover with the two (x2) screw holes and torque the screws (O) to 20 lb-ins.
