Wire SiZinG for 12 VDc input anD 24 VDc output connectionS
Recommended sizes of wiring for 2% voltage drop are as follows:
SteP 7: (Input current of 20A +/- 10% at battery Voltage of 10V and output current of
7A at 24V Nominal).

termination of connectinG WireS
Step 7 and Step 10: Use 6.3mm / 0.25” “Quick Connect”, female mating terminal on
the connecting wiring (See fig. 1, page 4)
This type of terminal is available for maximum wire size of AWG #10. When using wires
thicker than AWG #10, you may terminate the wire as follows:
• Use 6.3mm / 0.25” “Quick Connect” Female mating connector (AWG #10 size)
• Use around 2” piece of AWG #10 wire and crimp the connector to one end
• Solder / splice the other end of AWG #10 wire to the thicker wire
Use of short length of 2” of smaller AWG #10 wire will not increase voltage drop
appreciably.
