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).

WARNIN G
Wire and fuse sizes are dictated by electrical standar d s. 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 char ger may be an add iti onal 6 –10% abov e
the nominal current rating of the charger. Output current may also va ry depe nding on
ambient temperature conditions.
