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).

Connections
The screw terminals on the Distribution Cable Terminal
Block are labeled by function for clarity. The terminal
strip pocket will accommodate a spade lug or ring
terminal with a tongue width up to 0.320 inches. The
terminal screw size is 10-32. To make the connection,
attach an appropriate spade lug or ring terminal to the
wire, slip the fastener beneath the terminal screw and
tighten.
The Distribution Cable Terminal Block contains a cable
with a 20-pin plug connector. To connect the end of the
®
Distribution Cable Terminal Block to a Spectra
Molded-Case Circuit Breaker with a microEntelliGuard
RMS
TM
Trip Unit, insert the breaker cable plug into the terminal
block connector until the interlocks latch into the notch
and hold the plug in place (See Figure 8).
