Blackburn PTL 1000-8051 OH-PIN TERMINAL, MPT, BMS NO PLATE

The PTL 1000-8051 is sized for 954 to 1000 kcmil conductor. It is a compression connector, so the barrel is crimped onto the cable with a hydraulic tool and the correct die, not bolted or set-screwed. If your cable falls outside that 954 to 1000 kcmil range, you need a different size in the PTL series.

Pin length is 6 inches. That length is what lets a large 954 to 1000 kcmil cable land in a breaker, panel or meter socket lug that was only built to accept a much smaller conductor, and it gives you enough reach to seat the pin fully in a deep lug barrel. Check your lug depth and the clearance inside the enclosure before you crimp, since a 6 inch pin needs room to bend the cable in behind it.

You use one when the cable is too big for the terminal it has to land in. A pin terminal like the PTL 1000-8051 crimps onto the 954 to 1000 kcmil conductor and presents a small solid pin that drops into a mechanical lug rated for a much smaller wire. If the equipment lug already accepts your full conductor size, you do not need a pin terminal at all, just a straight compression or mechanical connector.

The body is aluminum with a bare finish and a tin-plated pin. Aluminum-bodied compression connectors of this kind are commonly dual rated for aluminum or copper conductor, but that rating is stamped on the connector and printed on the manufacturer's packaging, so read the marking on the part before you put it on copper. The tin plating on the pin is there so the pin can sit in a lug without the aluminum-to-copper contact problem.

No insulation. The PTL 1000-8051 is a bare-bodied connector, so you supply your own insulation, whether that is heat shrink, tape or a molded cover. That also means the crimp barrel is exposed and needs the clearances an uninsulated connector requires inside the enclosure.

The manufacturer part number is PTL 1000-8051, a Blackburn overhead pin terminal with a 6 inch pin for 954 to 1000 kcmil conductor. Order by that exact number, since the PTL family runs across many conductor sizes and pin lengths and the suffix is what separates them.

Sold each. One pin terminal per unit, so a three-phase plus neutral termination means ordering four, and a spare is worth adding since a mis-crimped compression connector cannot be reused.

Country of origin is the United States. That matters on public work and institutional jobs carrying domestic-content requirements, where the origin of every electrical connector on the submittal gets checked.
