I picked up two 12-foot lengths of stranded, 10 guage wire. After asking what others where using for wiring up the NPC 2212 motors, I decided to go with a thicker wire based on the higher amperage draw the motors have. 14 or 12 probably would have been fine, but why not play it safe
The clear tubing you see, a 1 foot length, is for the wires to pass between the outer ankle and into the leg. It will prevent the wires from being chaffed while "hiding" the red and black wires from view.
I took a closer picture in case anyone was wondering what the dimensions were...1/2" OD x 3/8". This holds both wires perfectly while not being too tight or too loose.
I'm still determining what I will need to power the motors. I'll have the batteries wired, in parallel (two 12 volt, 18amp), into a second fuse block. That fuseblock will hold a 30amp blade-style circuit breaker. The motors will then be wired into that.
That's all for now!
