WARNING!
!
Larger wires and tight connections will provide longer
service life for components. For high current wires it
is highly recommended that terminal blocks or
soldered connections be used with shrink tubing to
protect the connections. Do not use insulation
displacement connectors(e.g. 3M
® ) Scotchlock type
connectors). Route wiring using grommets and
sealant when passing through compartment walls.
Minimize the number of splices to reduce voltage
drop. High ambient temperatures (e.g. underhood)
will significantly reduce the current carrying capacity
of wires, fuses, and circuit breakers. Use "SXL" type
wire in engine compartment. All wiring should
conform to the minimum wire size and other
recommendations of the manufacturer and be
protected from moving parts and hot surfaces.
Looms, grommets, cable ties, and similar installation
hardware should be used to anchor and protect all
wiring.
Fuses or circuit breakers should be located as close
to the power takeoff points as possible and properly
sized to protect the wiring and devices. Particular
attention should be paid to the location and method
of making electrical connections and splices to
protect these points from corrosion and loss of
conductivity. Ground (Earth) terminations should
only be made to substantial chassis components,
preferably directly to the vehicle battery.
The user should install a circuit breaker sized to
approximately 125% of the anticipated maximum
current requirement to protect against short circuits.
For example, a 30 Amp circuit breaker should carry
a maximum of 24 Amps.
DO NOT USE 1/4" DIAMETER GLASS FUSES AS
THEY ARE NOT SUITABLE FOR
CONTINUOUS DUTY IN SIZES ABOVE 15 AMPS.
Circuit breakers are very sensitive to high
temperatures and will "false trip" when mounted in
hot environments or operated close to their capacity.
