4.1.5 Recommended Wire Gauge

VIN to J1: The connection between the source voltage, VIN and J1 of HPA241 can carry as much as 5 ADC. The minimum recommended wire size is AWG #16 with the total length of wire less than 4 feet (2 feet input, 2 feet return).

J2 to LOAD1: The power connection between J2 of HPA241 and LOAD1 can carry as much as 2 ADC. The minimum recommended wire size is AWG #18, with the total length of wire less than 2 feet (1 foot output, 1 foot return).

J3 to LOAD2: The power connection between J3 of HPA241 and LOAD2 can carry as much as 2 ADC. The minimum recommended wire size is AWG #18, with the total length of wire less than 2 feet (1 foot output, 1 foot return).
