Which gauge wiring should you use for your ESC?

RC Cars - Tech Tips - Which gauge wiring should you use for your ESC?

Silicon wire is the popular choice for electronic speed controllers (ESCs) in , RC cars, drones and other hobby electronics. 

Silicon wire has a number of advantages over other types of wire, including high flexibility, high temperature resistance, and good electrical insulation properties. These properties make them ideal for use in ESCs, which are subject to vibration, high temperatures, and other harsh conditions.

When selecting the correct gauge (thickness / capacity)  for an ESC, it is important to consider the current rating of the wire. This is typically measured in amperes (A) and indicates the maximum amount of current that the wire can safely handle. The current rating will depend on the wire's cross-sectional area and the material used. 

For example, a 18 AWG (American Wire Gauge) silicone wire will handle up to 15A and 22 AWG will handle up to 7A. In general, it is recommended to choose a wire gauge that is rated for at least double the maximum current that the ESC will draw.

Another consideration is the wire's resistance. Resistance is the measure of how much the wire resists the flow of electrical current, and it is measured in ohms. The lower the resistance, the better the wire will perform in terms of efficiency and power transfer. 

Additionally, color coded wire gauges are available for easy identification and organization of different connections. 

When it comes to installing the wire, it is crucial that the wiring is done correctly, and the wire is properly secured to prevent damage from vibration. Soldering the wire connections is generally recommended for a secure and durable connection.
