G'day all,
I've started acquiring everything to set up my 8 carriage set of the LGB LCE (70600) with a power car at each end to battery power and remote control.
I'm now at the point of sorting out wiring, which I'm pretty new to, and I'm still understanding how wiring works in regards to resistances, voltage drop etc.
So I was wondering if someone with more experience with electronics and wiring is able to see if what I plan to do sounds right, or if there's anything they recommend to make it better.
My current plan has the main components of the system, that being battery/receiever/soundcard etc, in one of the 2 middle carriages, as to lessen the distance and amount of plugs to each power car. The battery I'll be using it a 19.2V 4x4 AA NiMH battery from Fosworks.
I'll be using 6 wires; one each way for motor/speaker/lighting. With a 6-pin DIN plug between each carriage.
I'd roughly measured out that the line from the central block to the end carriage to be either about 2 or 2.5 metres, depending on which end. It will also have either 3 or 4 DIN plug connections to go through.
With extra wire in each section for a bit of reduncancy, that roughly makes a length of about 2.5 and 3 metres back and forth, give or take.
My main question comes with what gauge wire to use?
I've been told, and from what little I could find, 24 AWG wire is good to use. Though putting that into a voltage drop calculator, with 19.2V and what I assume it to use as 5amps, the drop comes to 2.5V, which sounds like a lot?
I don't know if that's significant enough to make a difference, or if 5amps is what goes through the wires.
I've looked into getting 18AWG wire, and that has a lot lower voltage drop. But is that suitable to use between the receiver/esc/soundcard as well? Or can I use a thinner gauge between those components, and use the thicker for the long run to each end?
Thanks for reading, and thanks in advance for any advice given. I think once I figure out what wiring I need to be using, I'll be on the home stretch to getting it all together.
