D) Dc Output Wiring - NewMar PT-14W Installation And Operation Manual

Do not mount the charger where there is a possibility of water entering the unit. Evidence of water
entry into the charger will void the warranty.
D) DC Output Wiring
Note: Only qualified service personnel should access the output terminals of the charger.
The installer will need to provide output wires. Use the table below to determine the correct gauge
wire, based on the length of the wire run from the charger to the batteries.
Model Length of Wire from Charger to Batteries (in feet)
10'
Minimum Wire Gauge AWG_____
PT‐24‐8W #18
PT‐24‐13W #16
PT‐14W #12
PT‐25W #10
*Based on N.E.C. Minimum Wire Size Chart and ABYC 3% Voltage Drop Chart
ENSURE THAT LEADS ARE PROPERLY FUSED AT THE BATTERY. (REFER TO ABYC
RECOMMENDATIONS.)
Typical DC wiring configurations are illustrated in FIGURES 1 and 2.

* Per ABYC A‐31: A DC chassis grounding
conductor shall be connected from the case of
the battery to the engine negative terminal or
its bus, and must not be more than one size
under that required for the DC current carrying
conductor and not less than 16 AWG.
Note: This diagram does not illustrate a
complete system. Refer to ABYC standards E‐11
AC & DC electrical system on boats.
IMPORTANT: Install fuses at batteries
per ABYC recommendations.
