Anderson Power Pole for motors

[adciv]

We've been using the powerpoles for several years now. We do not zip tie or use anything other than the natural friction between the connectors. The only issue we've had is the occasional plugging the wrong things together. We've never had anything come undone during competition. Mind you, we also make sure our robot wiring is fairly neat and well secured to the robot. We avoid birds nests on the robot.

It's overkill and very large, but this is FIRST. The PP15 crimp is for 16-20 AWG wire, just make sure you don't try using 22 AWG or the crimps won't work. During beta testing, we used 19AWG wire (I didn't even realize 19 existed until just now) and have had no issues. This included running it through an offseason competition.

I'm considering using some new connectors from molex but they won't be available until March, so next season?

We ordered the 15A connectors for the CAN bus wires and 18 gauge stranded hookup wire. I thought it was overkill, but if you're going to do it, you may as well overdo it

Yes, those look good! And with the 2.50 mm pitch, we can probably adapt them to 0.1" pin tech for the relatively short runs.

I completely glossed over this, but that looks like what I'd like to use, except for not being able to color code them like the power poles. I guess Sharpies would work. Bummer that they are unobtainium until March.

We've been having problems with the 12AWG stranded wire on the Victor SP's being too large for the PowerPole PP30 12-14 AWG contacts. We haven't had any problems with other 12AWG wire - has anyone else run into this?

It's a common problem that finely stranded wire has a considerably larger outer diameter than the solid round wire of the same gauge. I've seen that issue with other crimp connectors.

Maybe you could try Anderson's open-topped crimps instead of the ones with the closed barrel? Anderson sells slightly larger "super flex" connectors in some sizes that are intended to solve this specific problem.

Alternatively, it wouldn't be the end of the world to lose a few strands out of a 259-strand wire (if that's what they're using) over a short distance. The impact in terms of resistance would be negligible.
