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 Table
2.3.2. For longer runs, using 13mm² is recommended, however this will lower efficiency
by up to 3% (the recommended maximum length is 5m).

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