Install Sneak Fuse Panels

network interface and the system for both trunk and off-premises circuit packs.
The model 507B sneak current fuse panel, or equivalent, is recommended for
sneak current protection. See

Figure 1-22. Model 507B Sneak Fuse Panel
Approximately 8 inches (20 cm) of horizontal wall space is required for each
column of sneak fuse panels. Connector cables connect the network interface to
the sneak fuse panel. Also, use 157B connecting blocks equipped with SCP-110
protectors for sneak current protection.
NOTE:
Sneak current protectors with a rating of 350 mA at 600 V must be UL listed
for United States installations and CSA certified for Canadian installations.
The panel contains two 25-pair connectors, fuse removal tool, and fifty
220029 Sneak Fuses (and 2 spares). Use the SCP-110 protectors with
110-type hardware and on the 507B Sneak Fuse Panel. The SCP-110
Protectors can be ordered separately and installed on the 157B connecting
block. Fifty protectors are required per block.
