Blackburn PTB 400-6 – Frequently Asked Questions
1) What conductor size does the Blackburn PTB 400-6 pin terminal take?
The PTB 400-6 is sized for 397.7 through 400 kcmil stranded aluminum conductor. It is a one-conductor-size part, so it should not be used on a smaller cable to make up a difference in fill; match the run to the stated range or step to the correct barrel size.
2) Why would an electrician use a pin terminal instead of landing aluminum cable straight into the lug?
A pin terminal converts a large stranded aluminum conductor into a solid 6 inch pin that lands in a breaker, panelboard, or mechanical lug built for a smaller or solid connection. That is the whole point of the PTB 400-6: the compression barrel takes the 397.7-400 kcmil aluminum run and the tin-plated copper pin goes into the terminal. It avoids a loose or poorly seated strand bundle in a box lug.
3) Can I use this Blackburn pin terminal on copper cable?
No. The compression barrel on the PTB 400-6 is aluminum and the part is specified for aluminum conductor in the 397.7-400 kcmil range. For a copper run of the same size, use a copper compression pin terminal rated for copper instead.
4) Is the Blackburn PTB 400-6 a crimp fitting or a set screw fitting?
Compression. The barrel is crimped onto the conductor with a hydraulic tool and the proper die, not tightened with a set screw, so there is no torque value to check later and nothing to re-tighten at maintenance.
5) Does the PTB 400-6 pin terminal come insulated or do I need to cover it?
It ships bare, with no insulation on the body; only the pin is tin plated. Any insulating or sealing at the termination, heat shrink or tape, has to be supplied separately.
6) How long is the pin on the PTB 400-6 and will it reach into a deep lug?
The pin measures 6 inches, which is the long-pin version for terminals that need extra reach or where the pin gets cut to length in the field. If your equipment lug only needs a short stab, a shorter pin length in the same PTB family is the cleaner fit.
7) Is the Blackburn PTB 400-6 made in the USA?
Country of origin is the United States, which matters on public works and federally funded jobs carrying domestic sourcing requirements. The orderable part number is PTB 400-6.
