7.1.4
Banana Jack Connector and Spade Lug Terminals
This combination method provides a higher current rating and lower impedance of the load
connection. When input load currents are higher than 20A or the connecting lead wire is
long, this method will be optimal.
7.1.5
Plug Connector and Lead Wire Insertion
This method can also be used when the input current is higher than 20A or the connecting
lead wire is longer.
7.2
Wire Size
A major consideration in making input connection is the wire
size. The minimum wire size is required to prevent overheating
and to maintain good regulation. It is recommended that the
wires are sized large enough to limit the voltage drop at the
maximum current rating of the DC load to less than 0.5V per
lead.
If needed, wire size can be increased by doubling the number of
wires using two space lugs per side as shown in Figure 7-1.
