GEH-706 Installation Instructions
The Distribution Cable Terminal Block is used to carry a variety of electronic signals between Spectra® RMS Molded
TM
Case Circuit Breakers with microEntelliGuard
Trip Units. These breakers are interconnected via daisy-chained
terminal blocks with common power, communication wiring, and voltage wiring (SDCTBA22C only).
