wiring question for scope? Solid/Stranded/Gauge
Posted 12 March 2013 - 10:22 AM
For you electrical guru's,I am getting ready to wire up a scope.
On this scope there will be 3 fans, servo cat jr, sky commander powered by 12volt, and secondary mirror heater.
Any advantage to solid over stranded, where there is no movement or flexing needed?
What gauge, I am considering 16gauge or 18gauge for this application. Thanks for sharing!!

Your concern as the wire gets thinner is the voltage drop. It will act like a resistor between your battery and device. You will be happy with the 18 ga.

Telephone wires don't get that much flex in them & they still break, that's what you see with those overhead splice enclosures.
Stranded wire if there is any flex in your cabling. More smaller wires allows for more flex without breakage and still be able to carry your current draw.

Also switching transients like starting motors or electromechanical relays can induce voltage spikes in high impedance wires (i.e. small gage, long length wires) which may interfere with sensitive low voltage electronics like CCD cameras. IMO: the larger the wire gage and the shorter the wire length the better. Ferrite beads can help here http://en.wikipedia....ki/Ferrite_bead
I always use stranded wire for connecting wiring as stranded wire resists bending much better than solid. BTW my personal favorite hook up wire is Teflon insulated stranded silver plated copper conductor.
The bottom line is you will have to try out connecting wire size for your application.
