Xantrex Technology XC5012, XC2524, XC3012, XC1524 manual Wiring Requirements, DC Wiring

Introduction

Wiring Requirements

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.

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).
