Blackburn AL 1-38 TN – Frequently Asked Questions
1) What wire size does the Blackburn AL 1-38 TN compression lug take?
The AL 1-38 TN is sized for #1 STR AWG conductor. It is a one hole compression lug, so the barrel is crimped onto the conductor rather than clamped with a setscrew. Using it on a conductor other than #1 stranded will not give you a proper crimp.
2) Will this lug bolt to a 3/8 inch stud on my panelboard ground bar?
Yes. The AL 1-38 TN pad is drilled for a 3/8 inch bolt, single hole. The lug body measures 2-5/8 inches long by 3/4 inch wide, so check you have that much room on the bar before the next termination.
3) Can I use this aluminum lug on a copper conductor?
The AL 1-38 TN is an aluminum-body lug with a tin plated finish. Tin plating is what makes it suitable for terminating either aluminum or copper conductors of the rated size, and it is the standard dual-rated construction electricians look for on aluminum-body connectors. Size it to #1 STR AWG either way.
4) Is this lug rated for 90 degree C conductors like THHN or XHHW-2?
The lug carries a 90 degree C temperature rating, so it matches the insulation rating of common 90 C building wire. The termination temperature you actually size to is still set by the equipment rating at each end.
5) Does this compression lug meet a recognized connector standard for an inspected job?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference an inspector or spec writer looks for on a compression connector submittal. It is also made in the United States.
6) Should I use a compression lug or a mechanical setscrew lug for a #1 feeder termination?
A compression lug like the AL 1-38 TN is crimped permanently with a hydraulic or battery tool and the correct die, which gives a termination that will not loosen and needs no re-torque. A mechanical setscrew lug installs with a hand tool and can be taken apart later. Pick compression where the connection is permanent and you already have the crimp tool on site; pick mechanical where you may need to re-terminate or have no tooling.
7) Is the Blackburn AL 1-38 TN insulated, or do I need to cover the barrel?
No insulation on this one, the barrel is bare. If the termination needs to be covered you will need heat shrink or tape over the barrel and crimp area yourself.
8) Is this Blackburn lug sold individually or in a bag?
The AL 1-38 TN sells each, so order one per termination. Count both ends of every conductor when you are pulling a feeder.
