Install Sneak Fuse Panels

Sneak current protection is required between the incoming RJ21X or RJ2GX 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

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.
