Overview
The General Electric Distribution Cable Extension is
used to provide modular expansion of the Distribution
Cable System. The system is used to carry a variety
of electronic signals between Spectra
Case Circuit Breakers with microEntelliGuard
MicroVersaTrip
Cable Accessories. Accessories supported by the
Distribution Cable Extension are as follows:

cable
The Distribution Cable Extension is 30 inches in length
and can be group-connected to form a longer cable (the
total system cabling length must not exceed 40 feet).
Because both ends of the Distribution Cable Extension
are different (receptacle end / plug end), you cannot use
it for connections between Spectra
Circuit Breakers and Distribution Cable Accessories;
use the Distribution Cable Harness (Cat. Nos. SDCHA11,
SDCHA30 or SDCHA60) for this application.

Figure 3 shows the connector pinout for the Distribution
Cable Harness for each type of trip unit.
To disconnect the Distribution Cable Extension, press
down at the rear of the receptacle interlock until the
interlock clears the hook and remove the receptacle
(see Figure 5).

Connections
The Distribution Cable Harness contains a 12-pin
receptacle connector on each end. The connectors are
keyed so they cannot be inserted incorrectly into a
mating 12-pin plug connector.
To connect the end of the Distribution Cable Extension
to another Distribution Cable Accessory, align the
receptacle interlock with the plug hook and insert the
receptacle into the plug until the interlock and hook
overlap and catch (see Figure 4).
