Blackburn PTSG 4 – Frequently Asked Questions
1) What wire size does the Blackburn PTSG 4 pin terminal take?
The PTSG 4 is sized for #4 AWG stranded aluminum and #4 AWG ACSR conductor. It will not grip a smaller or larger conductor correctly, so match the run conductor to that size before crimping.
2) Can I use an aluminum pin terminal like the Blackburn PTSG 4 to land aluminum wire in a copper-only lug or breaker?
That is what it is for. The PTSG 4 crimps onto #4 aluminum or ACSR conductor and presents a solid pin, so the aluminum cable can be terminated into a breaker, meter socket, or panel lug that only accepts a copper pin or is too small for the stranded aluminum. It is built of aluminum and copper for that transition.
3) Is the Blackburn PTSG 4 a crimp connector or a set screw connector?
Compression only. There is no set screw on the PTSG 4, so you need a hydraulic or battery crimp tool with the correct die for the barrel. A mechanical set screw pin adapter is the alternative if you have no crimper on the truck.
4) What does shrouded mean on the Blackburn PTSG 4 pin terminal?
The shroud is an insulating sleeve over the barrel of the compression pin, so only the pin itself is exposed once the conductor is crimped in. It reduces the chance of a phase to phase or phase to ground flash inside a tight meter socket or panel gutter. The bare pin length on the PTSG 4 assembly is 1-7/8 inch.
5) Is the Blackburn PTSG 4 made in the USA for a government or public works job?
Country of origin on the PTSG 4 is the United States, which is the line item most public agency and Buy American submittals ask for on wire termination hardware.
6) Will the Blackburn PTSG 4 work on #4 copper wire?
No. It is specified for #4 stranded aluminum and #4 ACSR. For copper conductor you want a pin terminal rated for copper at that size; using this one on copper puts the conductor outside the listed range for the barrel.
7) Does the Blackburn PTSG 4 come in a pack or is it sold individually?
Sold each. Order one PTSG 4 per conductor you are terminating, so a three phase plus neutral service change takes four.
8) What is the exact Blackburn part number for a #4 shrouded compression pin terminal?
PTSG 4 is the Blackburn catalog number, and it is the number to quote for the #4 aluminum/ACSR shrouded compression pin with the 1-7/8 inch pin.
