Blackburn OAPA-250 AL TP SOLID OFFSET PIN TERM 250 BRN

The Blackburn OAPA-250 is an aluminum offset pin terminal, a cable or wire lug that converts a stranded conductor into a solid pin so it can land in a breaker, meter socket or lug jaw built to take a solid conductor. The offset design steps the pin off the axis of the cable barrel so the conductor can be routed around the terminal block. It is rated 600 V.

It carries UL file E63167. The terminal is rated for 600 V service, which covers typical commercial and industrial panel, meter and service-entrance work.

The body is aluminum, and the brown color coding on this pin terminal identifies it as an aluminum-conductor terminal rather than a dual-rated or copper-only part. Brown is the standard color code used on this family for the aluminum-only line, so if you are terminating copper you want a terminal identified for copper or marked AL9CU.

The 250 in the catalog number is the conductor size: it is sized for 250 kcmil aluminum cable, terminating into a solid pin. Order by that number, OAPA-250, since the pin terminals in this family are size specific and a 250 kcmil barrel will not grip a smaller conductor correctly.

Sold each, so you order one per conductor being terminated. On a three-phase plus neutral service that is four pieces per point of termination.

Use the offset version when the cable cannot come in on the same centerline as the landing point, which is common in tight meter sockets and panel gutters where the conductor has to be bent around adjacent phases. A straight pin terminal keeps the pin in line with the barrel and is the simpler choice when you have room for a direct approach. Both do the same electrical job of presenting a solid pin to a lug built for solid conductor.

Country of origin is the United States. That matters on public and institutional jobs carrying domestic-sourcing requirements for electrical materials.
