The Advanced Distribution Cable Junction Box has a 20-
pin plug connector on the front face labeled “BREAKER”.
This connector mates to the 20-pin receptacle
connector of the Spectra
®
RMS Molded-Case Circuit
Breaker with a microEntelliGuard
TM
Trip Unit. Figure 2
shows this “BREAKER” input connector pinout for the
Advanced Distribution Cable Junction Box.
The Advanced Distribution Cable Junction Box also
has two 12-pin plug connectors on the front face
labeled “HARNESS”. These connectors mate with the
12-pin receptacle connectors of a Distribution Cable
Harness (cat. nos. SDCHA11, SDCHA30 or SDCHA60). By
connecting to these plugs, the Advanced Distribution
Cable Junction Box provides a connection into or
out of the Distribution Cable System. Figure 3 shows
the “HARNESS” connector pinout for the Advanced
Distribution Cable Junction Box.
