===== Wire Gauge =====

{{http://diyaudioprojects.com/Technical/American-Wire-Gauge/American-Wire-Guage-AWG-Wire-Sizes.png?600}}

American wire gauge (AWG)is a standardized wire gauge system used since 1857 predominantly in North America for the diameters of round, solid, nonferrous, electrically conducting wire. Dimensions of the wires are given in ASTM standard B 258. **The cross-sectional area of each gauge is an important factor for determining its current-carrying capacity.** Increasing gauge numbers denote decreasing wire diameters.  That means the smaller the gauge number, the bigger the diameter.

Torque produced in an electric motor is proportional to the current (amps) it draws... more current (amps), more torque.  That means you need thicker wire for more current.  For the motor circuits it is common to use 12 AWG or 10 AWG wire depending on your electric current needs.  Typical amp capacity listed below [[http://www.engineeringtoolbox.com/wire-gauges-d_419.html|Ref]]

  * 12 AWG = 34 amps
  * 10 AWG = 52 amps

A good inexpensive source of wire is electric drier or range cords.  Usually 6-8 AWG 3-4 wires per cord, 3+ feet long and easy to separate wires. They are often left on appliances when set out for trash 

===== Connectors =====

==== Anderson Powerpoles ====

[[https://en.wikipedia.org/wiki/Anderson_Powerpole|Anderson Powerpoles]] are great connectors to use for your battery/motor load carrying circuits.  They work best with the proprietary crimp-tool which is a bit pricey but worth every penny.  You will be crimping a lot of connections over the course of your build, and having the proper tool makes all the difference.  If you can't afford the crimp tool, you may be able to borrow one from a local HAM radio club as Anderson Powerpole connectors are popular with that crowd.  Good sources for powerpoles are eBay, Amazon, and [[http://www.powerwerx.com/anderson-powerpoles/powerpole-sets/|Powerwerx]].

Make sure to order the right size for your amperage needs!

**Note:** Anderson Powerpoles are **highly recommended**.

==== Battery Connectors ====

Anderson SB50 Connectors are good for batteries. They use 10 AWG wire. You can't connect them in reverse. They are pretty damn durable. ([[https://powerwerx.com/anderson-sb-connectors-sb50-50amp|More on the Anderson SB50 Connectors]].)
