2.3.2 Output Wire Diameter Selection
REDARC recommends the installer use cabling and connections between 8B&S and 6B&S automotive.
REDARC recommends that the output wire be of the size outlined in Figure 2.3.2.1. For longer runs, using
6B&S (13 mm

) is recommended, however this will lower efficiency by up to 3% (the recommended
maximum length is 16'5" (5 m).

Recommended output cable size
REDARC recommend using the SBI12-BLD as
the 12 V relay for setting up the Load Disconnect
Feature for nonessential Loads.
Similarly, the SBI12-LLD is recommended for
use between the Auxiliary/House battery and
the Essential Loads in a Lithium Battery setup,
to protect the Lithium battery from excessive
discharge.
