Side Wall Kit
Product Description
The Side Wall Kit increases safety when an MEC or
MBC service box is installed outside of an enclosure.
These installations can leave the exposed right side
unprotected where it would normally be covered by
the enclosure. The Side Wall Kit protects service box
wiring and eliminates hazards made possible by
exposed internal components.
Newly produced service boxes have pre-drilled holes
for quick Side Wall Kit installation. However, earlier
service boxes require drilling prior to the Side Wall Kit
installation.

WARNING:
Shut down power to the service box before
removing or drilling.

or if it requires drilling. If the box requires drilling,
proceed to Step 2. If the box is pre-drilled, skip to
Step 4.
2. Verify that the service box is shut off and not
receiving power. In most cases, drilling holes as
indicated in Figure 1 will require removal of the
service box.
