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 (0) 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 (0) 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, grounds 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 (0) to 20
lb-ins.
Step 4: Branch Circuit Breakers WARNING: Leviton circuit breakers MUST BE
used with a Leviton circuit breaker enclosures.
a. Strip and connect the load power and load neutral wires to the load
terminals (0) and ground wire to the ground bus (R) of the circuit breaker
enclosure (fig. 11). Strip wires and torque load terminals to spec in the
terminations table.
NOTE: Ensure that the main breaker is in the OFF position before
installing any branch circuit breakers.
NOTE: Ensure that all branch circuit breakers are in the OFF position
before installing into the panel.
WARNING: TO AVOID RISK OF FIRE, check all wiring and ensure all circuit
breakers are installed in the proper position before energizing panel.
b. Align the hooks and guides (S) of the branch circuit breaker with the panel
and press until breaker snaps into place (fig. 12).
Step 5: Install Door a. Remove the main breaker knockout (T) if a main
breaker was installed. Do not remove in installations using the main lugs (L).
b. Twist-outs (V) must be removed for each position that contains a branch
circuit breaker.
c. To remove twist-outs (V), first strike with a screwdriver, then twist with
pliers until detached (fig. 13).
NOTE: Fill any unused open spaces in cover using filler plates (see
filler plate instructions).
d. Install door using the cover screws (provided).
e. Leviton covers contain a feature for adjustment in flush mounting
applications. In flush mount applications for covers larger than 42 spaces,
dead front interlock tabs MUST BE disengaged to allow for adjustment of dead
front position(fig.14a). Turn each adjustment screw (W) until the cover fits
tightly against the circuit breakers (fig.14b).
f. Apply circuit directory labels in the appropriate location, depending on
cover/door type.
Step 6: Complete the Installation WARNING: Before providing power to the
load center, check all electrical connections and confirm that the wiring is
correct.
a. Ensure that the main and all branch circuit breakers are in the OFF
position. To energize, first turn ON the main breaker, and then turn ON each
individual branch circuit breaker.
