November 2003
Each column of sneak fuse panels requires approximately 8 inches (20 cm) of horizontal wall space.
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 or CSA-certified for Canadian installations. The panel contains 2 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.
1 Install the 507B near the network interface or MDF with locally-obtained #12 × ¾-inch screws (or
equivalent).
