Enclosure Mounting
Surface Mounting (Indoor or Outdoor)
Secure the enclosure to the wall with appropriate fasteners. Use all pre-cut holes in the back of the enclosure for
mounting. See Figure 2.
Outdoor
1. Use the sealing gaskets provided if the mounting knockout locations shown in Figure 2 are used.
2. Use either one mounting hole at the top and two mounting holes at the bottom, or two mounting knockout
holes at the top and two mounting holes at the bottom. See Figure 2.
Surface Mounting
Temporarily position the enclosure with the centered tear drop hole. Secure the enclosure to the wall using the
four mounting holes.
Flush Mounting (Indoor Enclosure Only)
1. Remove the four small mounting knockouts on the side walls for securing to sixteen in. stud walls. See Figure 3.
2. Position the enclosure so that the front edge is flush with the finished wall.
3. Secure the enclosure to the studs through the small knockouts. See Figure 3.
Main Circuit Breaker or Main Lug Wiring
1. Pull the conductors into the enclosure. Use approved wire clamps, conduit bushings, or other approved
methods to secure the conductor to the enclosure and prevent damage to the conductor insulation.
2. Connect the main and neutral wires.
a. Install the main and neutral wires according to the wiring diagram on the load center.
b. Connect the service ground, equipment grounding wire, or both as required by the local electrical code.
c. Torque each connection to the value specified on the load center wiring diagram attached to the
enclosure.
3. If required by the local code, install the enclosed green neutral bonding screw through the hole in the neutral
bar. Thread the screw into the hole in the enclosure and torque to the value specified on the card shipped
with the bonding screw.
