Typical use is in lighting fixtures, appliances, and control cabinets where a quick, tool-less wire splice at 600 V is the goal.
Wiring and Current — the Wire-Gauge Trade-Off
The 2834048-4 accepts 16-22 AWG wire, and the current rating depends on which gauge you land: 8 A per circuit on 16 AWG, 3 A per circuit on 22 AWG. That dual rating is the derating curve in one line — the poke-in contact's temperature rise is lower with the larger conductor, so the full 8 A is only available at the heavy end of the wire range. For a lighting harness pulling 5 A per circuit, 18 AWG sits in the middle and runs safely; for a signal-only splice at 22 AWG, the 3 A ceiling is the limiter.
Rated for 10 mating cycles, this plug is a semi-permanent splice — you mate it once or twice during assembly and leave it. The tin contact finish supports that low-cycle duty; gold would be overkill for a connection that isn't meant to be broken repeatedly. If your application requires frequent disconnect (e.g., a service-disconnect point), look at a higher-cycle-rated connector in the same series.
