Installation

Wiring Requirements

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 both wires and fuses are correctly sized.
Maximum continuous current available from the charger may be an
additional 6–10% above the nominal current rating of the charger.
Output current may also vary depending on ambient temperature
conditions.

DC Wiring

The following two tables show some typical wire sizes, based
on 3% voltage drop on DC cables, 75 °C (167 °F) rated wire
and wiring being inside the engine compartment – assumed
ambient of 50 °C (122 °F).
