Depending on the model ordered, connections for the
ASL switch and auxiliary switch contacts are in one of
four forms. The standard wiring configuration is pigtail
leads exiting the rear of the base directly behind the
accessory. Optional configurations include a terminal
block mounted on the same side of the base as the
accessory, leads exiting the side of the base where the
accessory is mounted, and leads exiting the rear of the
base on the side opposite the accessory, The
long pigtail leads are color coded for identification; identi-
fication labels are provided for pigtail leads and terminal
block points. For allowable locations of all accessories,
refer to Product Selection Guide.
Note: No more than three pigtail leads can be routed
through the rear trough in the circuit breaker base.
When the walking beam interlock is used with the cir-
cuit breaker, the rear trough cannot be used for
accessory pigtail leads.
Before attempting to install the ASL switch or acces-
sory combination, check that the catalog number is
correct and the rating of the accessory(s) satisfies
the job requirements.
The ASL switch and accessory combination, as shown in
kit form in Fig. 2-1, can be installed in the right or left
accessory mounting cavity of a 2-,3-, or 4-pole circuit
breaker. An ASL switch or accessory combination must
be installed in the circuit breaker before the circuit
breaker is mounted in an electrical system. To install the
ASL switch or accessory combination, perform the follow-
ing procedures:
Note: A circuit breaker that is mounted in an electri-
cal system must be removed to install the accessory.
To ensure correct accessory installation, the circuit
breaker must be placed on a horizontal surface.
