4.2.7 Recommended Wire Gauge
• Input connection to the VIN and PGND terminal blocks (T1, T2, and T3) – The recommended wire size is
AWG #12, with the total length of wire less than two feet (1-foot input, 1-foot return).
• Output load connection to the VOUT_A, VOUT_B, and PGND terminal blocks (T5, T6, T7, and T8) – The
minimum recommended wire size is AWG #10, with the total length of wire less than two feet (1-foot output,
1-foot return). A thicker wire gauge can be required to minimize the voltage drop in the wires.
