Wiring Requirements
DC Wiring
The following two tables show some typical wire sizes, based on 3% voltage drop
(round circuit), 75 °C (167 °F) rated wire and wiring being inside the engine
compartment – assumed ambient of 50 °C (122 °F).
WARNING
Wire and fuse sizes are dictated by electrical standards. Different standards apply in
different countries and different types of installations, for example, boat, home or RV. It is
the responsibility of the installer to ensure that the installation complies with all applicable
standards.
CAUTION
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.
