5.1.5 Recommended Wire Gauge

VIN to J1: The connection between the source voltage, VIN, and J1 of HPA238 can carry as much as 5 ADC. The minimum recommended wire size is AWG #16 with the total length of wire less than four feet (two feet input, two feet return maximum recommended).

J2 to LOAD1 (Power): The power connection between J2 of HPA238 and LOAD1 can carry as much as 10 ADC. The minimum recommended wire size is 2× AWG #16, with the total length of wire less than two feet (one foot output, one foot return maximum recommended).
