Following are the basic characteristics for the control power and close and open operations of the AMVAC
TM
circuit
breaker.
DRAWOUT - STANDARD WIRING:
The schematic illustrates the basic wiring scheme for a drawout circuit breaker with standard wiring.
The point-to-point diagram illustrates the physical connections and wire numbers used in the wiring harness.
FIXED-MOUNT - STANDARD WIRING:
The wiring scheme for the fixed-mount circuit breakers is exactly the same except that there is no pin monitor/close
blocker switch so these connections are the same as if the switch in the truck is always closed. Also fixed mount break-
ers will come with 5 feet length of secondary wiring.
