Wiring Requirements
DC Wiring
The following two tables show some typical wire sizes for
various cable length runs, based on 3% voltage drop on DC
cables, 75 °C (167 °F) rated wire with wiring being inside the
engine compartment – assumed ambient of 50 °C (122 °F).
WARNING: Shock and fire hazard
Wiring and fuse sizes are governed by electrical codes and
standards. Different requirements apply in different countries and to
different types of installations, for example, boat, home or RV. It is
the responsibility of the installer to ensure that each installation
complies with all applicable codes and standards.
WARNING: Shock and fire hazard
Ensure that wires and fuses or breakered disconnects are correctly
sized.
Maximum continuous current available from the charger may be an
additional 6–10% above the nominal current rating of the charger.
