- Four (x4) mounting slots (E) have been precut on the side of the enclosure for installation between
- Pierce the foil tape (F) on side of enclosure with a mounting screw or
- If using 1/2 inch sheetrock, align the embossed (1/2) line with the front of the stud to achieve optimal flush mounting (fig. 3).
- Use the mounting slots (E) on both sides of enclosure to mount the enclosure with screws or nails (not provided) (fig. 3).
Step 3: Phase, Neutral and Ground Conductors WARNING: Use ONLY approved fittings and clamps to avoid damage to wires.
-
Bring the phase wires (G) , neutral (H) and ground (I) conductors into the enclosure through the predetermined
-
Determine whether or not the application requires the use of a main circuit breaker (J) (fig. 4) , or if main lugs (K) (fig. 5) can be used based on the local electrical codes
-
Connect the phase wires (G) , neutral (H) and ground (I) conductors to appropriate terminals and torque to spec in the terminations tabl e (fig. 4 or 5).
-
If installing with a main circuit breaker (J) , also install terminal covers (L) that have been provided (fig. 6).
-
When installing this enclosure as the service entrance, the bonding strap (M)
(included) MUST BE installed (fig. 7). Torque to 20 lb-ins.
- When installing this enclosure as a sub panel, DO NOT install the bonding strap (M). NOTE: For Service Equipment, apply “SERVICE DISCONNECT” label (provided) to trim, near main breaker
NOTE: For Branch Equipment, apply “MAIN” label (provided) to trim, near main breaker handle.
-
Connect the phase wires (G) , neutral (H) and ground (I) conductors to appropriate terminals and torque to spec in the terminations table (fig. 4 or 5).
-
If installing with a main circuit breaker (J) , also install terminal covers (L) that have been provided (fig. 6).
-

(included) MUST BE installed (fig. 7). Torque to 20 lb-ins.
- When installing this enclosure as a sub panel, DO NOT install the bonding strap (M). NOTE: For Service Equipment, apply “SERVICE DISCONNECT” label (provided) to trim, near main breaker
NOTE: For Branch Equipment, apply “MAIN” label (provided) to trim, near main breaker handle.
Step 5: Installing Cover (Sold separately)
- Remove the main breaker knockout (R) if a main breaker was Do not remove in installations using the main lugs (K).
- Twist-outs (S) must be removed for each position that contains a branch circuit
- To remove twist-outs (S) , first strike with a screwdriver, then twist with pliers until detached (fig. 10).
NOTE: Fill any unused open spaces in cover using filler plates
(see filler plate instructions).
- Install door using the cover screws (provided).
- Leviton covers contain a feature for adjustment in flush mounting
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.11a). Turn each adjustment screw (T) until the cover fits tightly against the circuit breakers (fig.11b).
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
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
