2.5 Wiring
The heavy gauge wires on the BCDC1250D unit carry peak currents of up to 55A
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. We recommend that this activity be undertaken by an appropriately trained
person.
REDARC recommends using a soldered butt splice crimp connection that is
covered with heatshrink. See Figure 2.5.1. 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 heatshrink will prevent any shorting/
contact with your vehicle chassis.
Crimp here.
Crimp both wires to the butt splice using
single-indent type crimpers. Fold the cable
over before inserting into the butt-splice as
required. Single-indent crimpers should also
be used on any lugs used.
Solder Both Ends Here.
Solder the wires to the butt splice. Ensure
that a good connection is made. Keep
heatshrink away until after soldering is
complete and has cooled.

2.6 Fusing
REDARC recommend using MIDI style bolt down fuses as
they ensure a low resistance connection. The REDARC
FK60 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.
A single fuse and holder
setup from the Fuse Kits
available from REDARC.
Part number FK60 (60A).
