An insulated type 600 volt crimp terminal for a 12-10 AWG is typically identified by which color code?

• A. Blue
• B. Purple
• C. Yellow
• D. Orange

Answer: (C)

The color code on insulated crimp terminals shows the wire gauge they’re designed to fit. For 12-10 AWG, the standard color is yellow, which matches that size range and ensures a proper crimp and secure electrical connection. The 600-volt rating is about voltage capability, not the wire size, so it doesn’t affect the color choice. Other colors correspond to different gauges—blue for 16-14 AWG, orange for 8-6 AWG, and purple isn’t the standard color for this size—so yellow is the correct match for 12-10 AWG.
