Model 507B sneak fuse panel
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 Underwriters
Laboratories, Inc. (UL) listed for United States installations and Canadian Safety
Association
(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.
1 Install the 507B near the network interface or patch panels with locally obtained #12 x
3/4-inch screws (or equivalent).
