Preparing For Installation
Note that every jurisdiction will have different requirements as will each
application, so research the regulations for your local jurisdiction to
determine which wire size and type is correct based on the maximum AC
input current marked on the chargers and given in “AC Input
Specifications” on page 54.
Other examples of AC wiring requirements:
• For marine applications, the American Boat & Yacht Council (ABYC)
requires stranded wire, which is more robust than solid wire when
exposed to vibration.
• For RV applications, the United States National Electrical Code (NEC)
allows solid wire in multi-conductor cable, however, stranded wire is
also acceptable which will withstand vibration better.
The AC wiring supplying the Truecharge2 Battery Charger must be
protected by the correct size and type of branch-circuit rated fuse or breaker
to meet the applicable installation codes. If a fuse is used instead of a
breaker, a correctly rated disconnect switch is required ahead of the fuse so
that power can be turned off, allowing fuse replacement and safe
maintenance of other equipment on the mains circuit.
Battery Bank Size Requirements
The Truecharge2 Battery Charger is designed to work with a minimum
battery bank size. Each bank should meet the minimum Ah rating shown in
Table 4. These minimum values are based on twice the charger’s rated
maximum charging current. For example, a 20-amp charger will charge a
minimum 40 Ah battery. If you are considering new batteries, please
consult the battery’s manufacturer for their recommendation based on the
maximum charging current of your charger.
IMPORTANT: If the battery manufacturer has specified the maximum
charge current, please follow their recommendation.
