Blackburn PTM 500-346 – Frequently Asked Questions
1) What wire size does the Blackburn PTM 500-346 pin terminal take?
The PTM 500-346 is built for 500 kcmil conductor, one size only. It is a compression connector, so the barrel gets crimped onto the cable with a die matched to the connector, not bolted or set-screwed. If your feeder is 350 or 600 kcmil, this is the wrong part number.
2) How long is the pin on the Blackburn PTM 500-346?
Pin length is 6 inches. That matters when you are reducing 500 kcmil down into a breaker or switch lug that will not accept the full cable: the long pin gives you the reach and the smaller cross-section the equipment lug can clamp on. Check that your enclosure has the gutter depth to take a 6 inch pin plus the crimped barrel.
3) Can I use an aluminum pin terminal on copper 500 kcmil cable?
The PTM 500-346 body is aluminum, and it is a bare, uninsulated connector. Aluminum-bodied compression connectors are commonly listed AL9CU for both aluminum and copper conductor, but that dual rating has to be read off the connector or its packaging for the specific catalog number. Match the connector to the conductor metal your feeder actually uses before crimping.
4) What is a pin terminal used for on a 500 kcmil feeder?
A pin terminal converts a large stranded conductor into a solid pin so it can land in equipment whose lug is too small for the cable, or in a lug designed for solid wire. You crimp the 500 kcmil cable into the barrel and the exposed 6 inch aluminum pin goes into the breaker, switch, or panel lug. It is not a splice and not a lug itself.
5) Does the PTM 500-346 come with insulation or a cover?
No insulation. The connector ships bare with no sleeve, boot, or coating, so the crimped barrel and the pin both need to be insulated or kept at clearance in the field. Plan on heat shrink or tape on the barrel if the installation requires it.
6) Do I need a special crimp tool for the PTM 500-346 pin terminal?
Yes, this is a compression terminal, so it takes a hydraulic crimper and the die called out for the connector on 500 kcmil. Mechanical set-screw lugs are the alternative if you do not have compression tooling on site, but they are a different part; this one cannot be torqued on.
7) Is the Blackburn PTM 500-346 sold individually or in a bag?
Each. The selling unit is a single pin terminal, so order one per conductor you are terminating. A three-phase run with a neutral needs four.
8) Is the Blackburn PTM 500-346 made in the USA?
Country of origin is the United States. That is the detail institutional and government procurement usually needs for domestic-content documentation on a bid.
