Installing Sneak Fuse Panels

The sneak fuse panel (Figure 2-18) must be installed as near as
possible to the network interface. To install the sneak fuse panel,
proceed as follows:
1.
Hold the panel against the mounting surface and mark the upper
right and lower left mounting screw locations.
2. Drill pilot holes at the marked locations, and partially install the 3/4
inch No. 12 screws.
3. Slide the sneak fuse panel onto the mounting screws and tighten
the screws.
4. Repeat the procedure for each sneak fuse panel.
