Over-current Protection Disconnect
Electrical codes require the DC circuit from each battery to the
charger to be equipped with a disconnect and an over-current
protection device, usually within 7 inches (17.8 cm) of each
battery. The devices are usually DC-rated circuit breakers, fused
disconnects, or a separate fuse and disconnect for each circuit.
These devices must be rated for DC voltage and current and be
rated to withstand the short circuit current available from the
connected battery bank. Do not substitute devices rated only for
AC voltage; they may not operate properly.
The current rating of the DC fuses must be correctly matched to
the size of the DC wiring used, in accordance with the applicable
codes. This helps to protect the installation against fire in case of
any overcurrent or short circuit fault.

DANGER
FIRE HAZARD
Use only on circuits provided with 20A maximum branch circuit
protection in accordance with local and national electrical codes*.
Failure to follow these instructions will result in death or serious
injury.
* Applicable codes in North America are the US National Electrical Code (NFPA 70) and Canadian Electrical
Code (CSA C22.1) and the American Boat and Yacht Council (ABYC) standards and US Coast Guard
Regulations (33CFR183, Sub Part I) for Marine installations in the USA.
* Applicable codes in Europe are the IEC/EN 60364-X-Y series of standards.
The AC mains wiring must be of sufficient size and it must be
protected by the appropriate size and type of input breaker based
on the jurisdiction and application. Some basic examples are
given below.
The AC mains input wiring for the XPLORE Charger should be
three-conductor cable, providing a ground/earth , line, and neutral
conductors (or G/PE, L, N) in an outer jacket, rated a minimum of
75 °C, and sized based on the AC input current to the charger (see
AC Input Specifications on page 55
) and on the value of
overcurrent protection provided.
