Blackburn AL 1000 CPTNTN – Frequently Asked Questions
1) Will this two hole lug bolt to a 1-3/4 inch NEMA bus pad?
Yes. The pad holes are on 1.750 inch centers, which is the standard two hole spacing for large NEMA bus drillings. Pad dimensions are 3.625 long by 2.443 wide by .639 thick, so confirm you have that much landing room on the bus or breaker pad before you crimp.
2) Can I use this aluminum lug on copper conductor?
It is an aluminum body lug with a tin plated finish, which is what makes it suitable for terminating either aluminum or copper in a dual rated application, and the tin plating is also what protects the aluminum pad against corrosion where it lands on a copper bus. It meets ANSI C119.4, the standard covering connectors for aluminum and copper conductors.
3) Do I need a hydraulic crimper for this lug, or can it be bolted on?
This is a compression terminal, not a mechanical set screw lug, so the barrel has to be crimped onto the conductor with a die type compression tool. At 1000 kcmil that means a hydraulic crimper with the correct die. If you need a connection you can make with a wrench only, look for a mechanical lug instead.
4) Is this lug rated for 90 degree C conductor?
Yes, the temperature rating is 90 C, so it can be used where the cable insulation and the equipment terminations are rated to that level. It is a bare lug with no insulation, so the connection gets covered in the field with heat shrink or tape if your installation calls for it.
5) Does the AL 1000 CPTNTN lug come with the bolts to land it on the pad?
No. It ships as a bare two hole lug, sold each, with no mounting hardware. You supply the bolts, nuts, flat and Belleville washers to suit the 1.750 inch hole centers and the pad drilling on your equipment.
6) Is this Blackburn lug made in the USA for a Buy American job?
Country of origin on the AL 1000 CPTNTN is the United States, which is the documentation institutional and government procurement typically asks for. It also carries the ANSI C119.4 connector standard called out on many electrical specs.
7) Why pick a two hole pad lug over a single hole for a 1000 kcmil feeder?
A two hole pad on 1.750 inch centers keeps a heavy 1000 kcmil cable from rotating on the bus under fault or vibration, which is why most switchgear and transformer terminations spec it. A single hole lug is fine on light branch work but lets a large cable twist. If your equipment pad is only drilled for one bolt, a two hole lug will not land.
