Ring Terminal for 16 AWG Copper Wire

The Sta-Kon A18-12 is a non-insulated ring terminal designed for 16 AWG copper conductors. It accepts wire sizes from 22 AWG up to 16 AWG and carries a 600 V rating. The terminal features a tin-plated copper body with a serrated barrel for secure crimping. It is UL Listed and CSA Certified for electrical applications.

Sustained Load Behaviour

The tin-plated copper contact resists corrosion during continuous operation up to 221 degrees F. The serrated barrel maintains mechanical grip on the conductor under vibration or thermal cycling. With no insulation sleeve, heat dissipates directly from the barrel. The 600 V rating applies to continuous service within the temperature limit.

Installation and Common Issues

Crimp the barrel using a tool matched to 16 AWG non-insulated terminals. The 0.32 in barrel length and 0.72 in tongue width require alignment on a 1/2 in stud with 0.38 in hole spacing. Common issues include loose crimps from undersized tools and strand damage if 22 AWG wire is over-crimped. Verify stud size before terminating.

Questions about this item

How hot can the A18-12 terminal get when current flows all day?

The maximum operating temperature is 221 Degrees F, so the connection stays within spec under continuous load at 600 V.

What crimp tool and wire gauge do I need before installing this ring terminal?

Use a crimper made for serrated barrels and 16 AWG copper wire; the barrel accepts 22 AWG to 16 AWG conductors.

Will the 1/2 in stud hole line up with the 0.38 in spacing on my existing terminal block?

Yes, the hole spacing is 0.38 in and the tongue width is 0.72 in, matching common 1/2 in stud patterns.
