Blackburn SA 2-38 TN – Frequently Asked Questions
1) What wire sizes does the Blackburn SA 2-38 TN compression lug take?
The SA 2-38 TN is rated for #1 to #2 stranded AWG and #1 compressed/compact AWG conductor. Match the conductor to that range before you crimp; a compression lug is a one-shot connection and an undersized or oversized conductor will not give you a sound termination.
2) Can I use the Blackburn SA 2-38 TN aluminum lug on copper conductor?
The SA 2-38 TN is an aluminum body lug with a tin plated surface. Tin plating is what allows an aluminum connector to be used on either aluminum or copper conductor without direct dissimilar metal contact at the barrel and the pad. Confirm the conductor falls in the #1 to #2 stranded range either way.
3) Is this a one hole or two hole lug, and will it land on a standard bus pad?
One hole. The SA 2-38 TN is a single bolt hole compression lug, so it lands on a single tapped or drilled pad and it can rotate on the bolt under torque. If your pad is drilled for two bolts on NEMA spacing, or you need the terminal held against rotation, you want a two hole lug instead.
4) What standard does the Blackburn SA 2-38 TN compression lug meet?
It is built to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. That is the reference an inspector or a spec writer will be looking for on a compression terminal in a panel or switchgear termination.
5) How long is the SA 2-38 TN lug, and will it fit in a tight gutter?
Overall length is 1-5/16 inch. That is a short body, so it works in shallow gutters and crowded panel terminations where a long barrel lug would bind. There is no insulation on it, so plan for clearance or apply your own heat shrink after crimping.
6) Should I use a compression lug like this or a mechanical set screw lug?
A compression terminal like the SA 2-38 TN is crimped with a die tool and is permanent, which is what most engineered specs call for on feeders because there is nothing to re-torque over time. A mechanical set screw lug is the choice when you need to terminate in the field without a crimper, or you expect to change the conductor later. If the drawing calls out compression, this is the type you want.
7) Does the Blackburn SA 2-38 TN come insulated or do I need to sleeve it?
It ships bare. Insulation material is listed as none, so if the application calls for a covered termination you add your own heat shrink or boot after the crimp.
8) Are Blackburn SA 2-38 TN lugs sold individually or in bags?
Each. The selling unit on the SA 2-38 TN is a single lug, so order one per conductor termination and remember phase plus neutral plus ground when you count out a feeder.
9) Is the Blackburn SA 2-38 TN made in the USA?
Yes, country of origin on the SA 2-38 TN is the United States, which matters if you are working a government, federal, or Buy American funded project with domestic content requirements on electrical materials.
