American Wire Gauge (AWG) is a logarithmic stepped 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.

You can crimp both Large (ex: 150 AWG) and small (ex. 20 AWG) wires. However, keep in mind that the crimping process might differ based on the wire size. For larger gauges like 100 AWG, you’ll need appropriate crimping tools and connectors designed for thicker wires.

Items needed for wire Crimping

1. Crimper Tool to remove insulation
   

2. Ferrule Caps for the copper wire

3. AWG Gauge Wire (20 AWG in this example)
   
4. Wire Strippers to strip correct Wire Guage

5. Wire Cutter to cut excess copper wire
   

1. Fit Crimper onto insulation of wire, then clamp and remove it.

2. Once insulation is removed, slide ferrule caps onto the appropriate wire (in this example, red and black wire)

3. Cut excess wire with the wire cutter 

4. Congratulations! You have just safely crimped and capped the electrical wire.
