Blackburn AL 2-48 TN – Frequently Asked Questions
1) What wire size does the Blackburn AL 2-48 TN compression lug take?
The AL 2-48 TN is sized for #2 STR AWG conductor. One conductor, one barrel, crimped with a compression tool. If your cable is #1 or 1/0, this is the wrong lug and you need the next size up in the series.
2) Can I use this aluminum lug on copper conductor, or is it aluminum only?
It is a tin plated aluminum body lug. Tin plating on an aluminum barrel is what makes a connector dual rated in practice, and the AL 2-48 TN is built and tested to ANSI C119.4, the standard for connectors used on aluminum and copper conductors. For a copper-only installation many electricians still prefer a copper compression lug; for aluminum feeder terminations the tin plated aluminum body is the standard choice.
3) What temperature is this compression lug rated for?
90 degrees C. That matches 90 C rated building wire such as THHN or XHHW, so the lug won't be the limiting item in a termination sized at the 75 C or 90 C column.
4) Does this lug come with insulation or a heat shrink sleeve?
No. The AL 2-48 TN is a bare, uninsulated lug. If the termination needs to be covered, you add heat shrink or a molded boot separately.
5) Should I use a compression lug or a mechanical set screw lug for a #2 feeder?
A compression lug like the AL 2-48 TN is crimped permanently with a die tool, which gives a consistent connection that does not need retorquing and is what inspectors and utilities generally expect on aluminum. A mechanical set screw lug installs with nothing but a wrench, so it is the practical pick for field changes, small panel work, or where no crimp tool is on site, but the set screw wants checking over time. Pick compression when the termination is permanent and you own the tool.
6) Is the Blackburn AL 2-48 TN made in the USA? We have domestic sourcing requirements.
Country of origin is the United States. For government, institutional, or federally funded work with domestic preference language, the AL 2-48 TN is a US origin connector built to ANSI C119.4.
