Constructing a Power cable
Special care should be taken when making the connections for DC power. It is easy to make a mistake
when crimping connections, and there is a very good tutorial available at Molex:
http://www.molex.com/tnotes/crimp.html
The specifications for the wiring are as follows:
•
16 AWG (1.02-to-1.29mm)
•
UL1015 Rated
•
Wires will be wound at 1 twist per inch
The example in
shows a cable constructed with a ferrite for a different certification. You can
build your cable without the ferrite eliminating items 2 and 3 in the diagram.
