Blackburn PTA 500 – Frequently Asked Questions
1) What conductor sizes does the Blackburn PTA 500 pin terminal accept?
The PTA 500 is sized for 4/0 stranded AWG through 500 kcmil aluminum or copper conductor. It is a compression fitting, so the barrel is crimped onto the cable with a die-type tool rather than bolted or set-screwed. If your feeder is smaller than 4/0, this barrel is too large to get a proper crimp and you need a smaller pin terminal in the series.
2) Why would I use an aluminum pin terminal instead of a lug on a large feeder?
A pin terminal converts a large stranded cable into a solid pin so it can land in a mechanical set-screw terminal, such as a breaker, panel lug, or disconnect that was never sized for 500 kcmil stranded aluminum. The PTA 500 crimps onto 4/0 through 500 kcmil cable and presents a 6 inch tin-plated solid copper pin. If your equipment terminal is already rated for the full stranded conductor, a standard compression lug is the simpler choice.
3) Will the Blackburn PTA 500 work on copper cable or only aluminum?
The body is aluminum with a tinned solid copper pin, which is the standard dual-rated construction for AL/CU service. Pin terminals of this type are commonly applied to both aluminum and copper conductors in the stated 4/0 to 500 kcmil range. On aluminum conductor, brush and apply the joint compound your installation practice calls for before crimping.
4) Is the PTA 500 pin terminal insulated, and do I need to tape or boot it?
No insulation is supplied. The barrel is bare aluminum and the pin is tin-plated, so the connection is exposed once crimped. In a panel or gutter where clearance to grounded metal or adjacent phases is tight, plan on a heat-shrink sleeve or insulating boot sized for a 500 kcmil barrel as a separate item.
5) Does the PTA 500 come in a package or is it sold individually?
Pin terminals in this line sell each, so quantity is per piece. For a three-phase feeder plus neutral you would order four, and for a full four-wire set on a parallel run you multiply by the number of conductors per phase.
6) Is the Blackburn PTA 500 pin terminal made in the USA?
Country of origin is the United States, which matters on public work and institutional projects carrying domestic-preference language in the spec. Order by manufacturer part number PTA 500.
