30 guage servo wire?

[village_idiot]

Where can I get good quality, multi-strand 30 guage servo wire?

Maxx products has 32 guage that is pretty good:

Thanks, that might work out just fine.

32 gage is awfully small. Recommended current capacity for 30 gage is 144 milliampers and most servos draw much more than that. Fusing current on 30 gage is 10.2 amperes. 22 gauge is a more resonable size with 918 milliamperes steady current 41.2 amps fusing current. Resistance of 30 gage is 105 ohms/1000 ft., 22 gage is 16.46 ohms/1000 ft.

You can also try flat cable, like this:

Very light, that one I think is 2mm pitch, but there´s also 1mm pitch.

The cable that comes on the servos is only around 30 gauge, so not sure what they are thinking. It definitely was not 28 guage wire that they used, so that leaves 30 or 32 for choices. I thik I ended up with 30 gauge from a different place because they had a few other items I needed.

That is the "power transmission" rating. Based on that 14 Ga is only good for 5.9 amps, but in our applications it is good for >60 amps.

Using the "Chassis wiring" standard 30 ga is rated for .86 amps, but even that is very conservative.

I use the 32 gauge wire all the time in small models with micro servos. No problems at all.
