Blackburn PTB 350 TN – Frequently Asked Questions

1) What wire size does the Blackburn PTB 350 TN pin terminal take?
The PTB 350 TN is sized for 336.4 kcmil through 350 kcmil stranded conductor, and it's built for aluminum cable with a tin-plated copper pin on the output side. One terminal per conductor, sold each.
2) How is the Blackburn PTB 350 TN attached to the cable - is it a set screw or crimp connector?
It's a compression fitting, not a mechanical set screw lug. The barrel is crimped onto the conductor with a hydraulic or battery compression tool and the correct die, so plan on having a crimper on site.
3) Why would I use a pin terminal instead of a standard aluminum compression lug?
A pin terminal converts a large stranded cable into a solid round pin so it can land in equipment that only accepts a pin or a screw-clamp terminal, such as breaker or panelboard lugs that won't take a bolted pad. If your gear has a bolt-hole pad, you want a compression lug instead. The PTB 350 TN gives a 4 inch pin off 336.4 to 350 kcmil cable.
4) Can I use the Blackburn PTB 350 TN on copper conductor as well as aluminum?
The barrel is aluminum and the terminal is specified for 336.4 to 350 kcmil aluminum cable. The tin plating is on the copper pin, which is what makes the pin safe to land in a copper or aluminum equipment terminal. For copper feeder cable, use a copper compression pin terminal in the same kcmil range rather than this one.
5) Does the Blackburn PTB 350 TN come insulated or do I need to tape and shrink the barrel?
Bare metal, no insulation on the barrel. If the installation needs the barrel covered, add adhesive-lined heat shrink or tape it out as part of the terminaton.
6) Is the Blackburn PTB 350 TN made in the USA?
Yes, country of origin is the United States. That matters on public and federally funded work where domestic sourcing is written into the spec.
7) How many Blackburn PTB 350 TN terminals do I need for a three-phase 350 kcmil feeder?
One per conductor. A three-phase feeder with a neutral in 350 kcmil takes four, plus one more for each parallel set. They are sold individually, not in kits or pairs.
