Blue Sea Systems C-Series Toggle Circuit Breakers for High Load Applications - Manual (Page 2)

Installation
1. Disconnect all DC power
Before installing, disconnect the main positive cable from all batteries
to eliminate the possibility of a short circuit while installing the circuit
breaker.
2. Select mounting location and cut opening
Select a mounting location which is protected from water on the panel
front and back and is not in an area where fl ammable vapors from
propane, gasoline or lead acid batteries accumulate.
3. Install positive feed wires
Determine the positive (red) wire size by calculating the total amperage
of the circuits that will be routed through the circuit breaker using the
Wire Sizing Chart. Remember that the length of the circuit is the total
length of the positive wire from the power source to the device and the
length of the negative wire back to the DC negative bus.
Rotating the line positive bus on the line side of the breaker 180
degrees will allow the line positive and load positive wires to hang
down from the panel without interfering with each other. If rotated re-
torque the 1/4-20 Nuts to 35 inch lbs maximum.
Connect the line positive and load positive wires to the circuit breaker.
DO NOT make any connections to the coil shunt (see diagram).

@ This is a DC device! It should not be confused with AC double pole
circuit breakers used for simultaneously breaking AC hot and neutral
circuits.
