Blackburn SA 3-38 – Frequently Asked Questions
1) What wire size does the Blackburn SA 3-38 compression lug take?
The SA 3-38 is sized for #2 AWG stranded conductor, compression installed. It is a single-conductor, one hole lug, so one #2 run per lug. If your feeder is a different gauge, you need a different die-coded lug, not this one, because compression lugs are barrel sized to the conductor.
2) Will the SA 3-38 lug bolt to a 3/8 inch ground bus stud?
Yes. The pad on the SA 3-38 is drilled for a 3/8 inch stud or bolt, single hole. That covers most panelboard ground bars, switchgear lugs pads and busbar terminations using 3/8 inch hardware. Bolt and washers are not part of the lug itself.
3) Do I need a crimp tool for this lug, or can I tighten it with a wrench?
It is a compression lug, not a mechanical set screw lug. Termination requires a hydraulic or battery crimper with the correct die for a #2 aluminum barrel. If your crew does not carry a crimper, a mechanical lug with a set screw is the type to specify instead.
4) Can I use an aluminum lug like the SA 3-38 on copper wire?
The SA 3-38 is an aluminum body lug and it meets ANSI C119.4, the standard covering connectors for aluminum and copper conductors. What it is listed for on your job is set by the connector's own dual-rated marking, so read the barrel stamp before you crimp copper into it. The catalogued conductor for this lug is #2 stranded.
5) Is the SA 3-38 insulated, and does it need taping after crimping?
Bare aluminum, no insulation on the barrel or pad. In a panel or on a ground bus that is normally fine. On an insulated phase conductor termination where you want the barrel covered, plan on heat shrink or tape, or specify an insulated lug instead.
6) How long is the Blackburn SA 3-38 lug? I have tight gutter space.
Overall length is 3-1/8 inches from the end of the barrel to the far edge of the tongue. Worth checking against your gutter or wireway depth before you crimp, because once the die is set the lug is committed to that conductor.
7) Does the SA 3-38 meet spec for a connector called out to ANSI C119.4?
Yes, the SA 3-38 is built to ANSI C119.4, which is the standard for electric connectors used on aluminum and copper conductors. That is the line a spec writer or inspector usually looks for on a grounding or feeder lug submittal. Order by manufacturer part number SA 3-38.
8) Is the SA 3-38 sold individually or in a bag?
Sold each, one lug per unit, so you can buy the exact count a termination schedule calls for rather than a bag quantity. It is made in the United States.
