Sta-Kon RA18-6 Ring Terminal #6 Stud 16 AWG 600 V Nylon Insulated

Electrical connector for 16 AWG copper wire

The Sta-Kon RA18-6 ring terminal accepts copper conductors from 22 AWG up to 16 AWG and is rated for 600 V. Its tin-plated copper barrel uses a serrated crimp style to secure the wire. A #6 stud hole with 0.25 in spacing mounts the tongue, which measures 0.26 in wide. The nylon insulation provides partial coverage and is coloured red for quick identification.

Thermal rating and sustained current handling

The nylon insulation is rated to a maximum operating temperature of 221 Degrees F, setting the practical thermal limit for continuous use. Because the barrel is crimped rather than soldered, the joint resistance remains stable as long as the crimp tool matches the serrated barrel dimensions of 0.46 in length. Exceeding the temperature rating risks insulation degradation and increased contact resistance over time.

Standards and voltage interface limits

The terminal carries UL Listing E9809 and CSA certification, confirming compliance with North American safety standards for 600 V applications. The 600 V rating defines the maximum voltage the insulation and creepage distances can withstand. Users must ensure the connected circuit does not exceed this voltage and that the stud size matches the #6 requirement for proper mechanical retention.
