Distribution Cable Terminal Block

Overview

The General Electric Distribution Cable Terminal Block

is a modular attachment primarily used to provide an

alternate means of input to Spectra

RMS Molded-Case

Circuit Breakers with microEntelliGuard

Trip Units. The

terminal block input/output connections are as follows:

Neutral current sensor input is required for 3Ø /4W or 1Ø /3W systems. For 3Ø /3W systems, do not make any connections.

The Distribution Cable Terminal Block is used to carry a variety of electronic signals between Spectra

RMS Molded

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).

Figures 1 and 2 show how the Distribution Cable Terminal Block is used in a typical microEntelliGuard

system.

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

RMS

Molded-Case Circuit Breaker with a microEntelliGuard

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).
