Wire????

[ReddyWatts]

What kind of wire are you using when you add length or change wires to the ESC, full spec copper, copper clad aluminum or what? This video shows the difference in wire performance. You need to pay attention to what you are using.

When it comes down to that kind of specs I wouldn't trust no less than mogami or monster cable

[ReddyWatts]

I have been guilty of using some wire laying around in the garage. There is a difference. Only buy the good stuff for use in your boats

GOOD LUCK finding good wire u can get it on here but thats about it

Just look for a high strand copper wire(awg appropriate) and you'll be fine.

This is what I use on the high amp, high voltage boats, Pure copper 8g. The video confirms my thoughts about it being very good wire, and its about $1.10 per foot. I use 10g on everything else.

There are alot of RC boaters out there that may not realize how important good, large guage wire can be in any setup. I'd rather it be too large than too small. Precious amps and voltage are lost as can be seen in the video.............the 'bad' wire suffered a whole volt less in loss and got to 215*!!!!!!!!!

That volt can easily keep you back in third place rather than being on the top tier in the winners circle..............

I only use Tinned pure copper wire. Tinning eliminates the "black death".

Skin Effect and Skin Depth Notes: Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor so that the current density near the surface of the conductor is greater than that at its core. That is, the electric current tends to flow at the "skin" of the conductor. The skin effect causes the effective resistance of the conductor to increase with the frequency of the current.

More strands is better on the motor side (AC) of the ESC. More copper is better on the battery side (DC) of the ESC.

[JrValente]

In our applications you need the flexability to manuver the wires and for the durability, so that is why I recommend the high strand wire.

[ReddyWatts]

I agree, but this is why we can use a rigid copper dc bus in a hv application on the batteries. We have to use high stranded copper wire on the motor side due to the ac and frequency that changes the wire resistance.

[jcald2000]

Reddy, so pulsed DC is effectively AC??

[ReddyWatts]

It has a frequency.

[siberianhusky]

It's dc, frequency or not the voltage never swings negative.

[ReddyWatts]

Compare it to an audio signal in the video, it has the same effects to heat the wire. Does not have to be a sine wave.

[siberianhusky]

Yes but your answer above implied that it was AC because it had a frequency and thats not quite right. It's still DC voltage you're dealing with. Even though it has a rise and fall from switching it never switches direction, it just turns on and off, it always stays between 0 and you max positive voltage.
