Plasti-Grip spade, 10-12 AWG, #10 stud
The 52856-1 is a flanged spade terminal from the TE Connectivity Plasti-Grip series, accepting 10-12 AWG wire and fitting a #10 stud. The yellow PVC insulation covers the crimp barrel and a portion of the wire, with a serrated inner barrel for grip on the conductor. Tin-plated copper contact material is standard for this series.
Yellow insulation signals wire range
The yellow PVC colour is the industry-standard identifier for the 10-12 AWG wire range within the Plasti-Grip family — the same colour code runs across ring, spade, and hook terminals in the series.
