5.3 FUSING
REDARC recommends using MIDI style bolt down fuses as they ensure a low resistance
connection. The REDARC FK40 fuse kits are recommended.
Blade type fuses are not recommended as they can result in a high resistance connection which
causes excess heat and may damage the fuse holder and/or the wiring.
Self-resetting circuit breakers are not recommended as they may trip prematurely due to the heat
generated by the current flowing through the wires.

5.4 CABLE CONNECTIONS
CAUTION: Cable and fuse sizes are specified by various codes and standards which depend
on the type of vehicle the Battery Charger is installed into. Selecting the wrong cable or fuse
size could result in harm to the installer or user and/or damage to the Battery Charger or other
equipment installed in the system. The installer is responsible for ensuring that the correct
cable and fuse sizes are used when installing this Battery Charger. Cabling is recommended to
be away from heat sources and in protected areas, especially when installing or routing in the
engine bay.
The wires on the BCDC1220 and BCDC1220-IGN Unit carry peak currents of up to 30Amps and
it is important to make a good, low resistance, electrical connection that will not degrade over time.
Failure to make a good, reliable contact may result in breakdown of the wire insulation and cause
a short circuit, or worst case a fire. REDARC recommend that this activity be undertaken by an
appropriately trained person.
REDARC recommends using a soldered butt slice crimp connection that is covered with heat-shirnk
(see "Figure 5: Ensuring a good wiring connection"). REDARC does not recommend using standard
red/blue/yellow blade connections, as they are not rated for either the current required or gauge of
wire supplied on the Unit.
Crimping provides good mechanical connection, soldering provides a long lasting electrical
connection and forming of the heat-shirnk ill prevent any shorting/contact with your vehicle chassis.
