Blackburn AL 500 N 32 HS – Frequently Asked Questions
1) What wire size does the Blackburn AL 500 N 32 HS compression lug take?
The AL 500 N 32 HS is sized for 477 to 500 kcmil and 500 to 600 kcmil conductor. It is a compression lug, so the barrel is crimped onto the conductor rather than bolted, and the conductor has to fall in that kcmil range for the die set and barrel to give a proper crimp.
2) Is the Blackburn AL 500 N 32 HS a two-hole NEMA pad lug?
Yes, it is a two-hole straight tongue lug with a NEMA-spaced pad, so it lands on standard two-hole bus and equipment pads. Two-hole termination resists rotation under load, which is why it is specified for switchgear, panelboard and transformer terminations instead of a single-hole lug.
3) What does the 32 inch length on the AL 500 N 32 HS mean?
32 inches is the overall length of the lug, an extra-long barrel and tongue version rather than a standard short-barrel lug. That length is used where the termination has to reach across a cabinet or up a bus riser without a splice. If your gear has a short landing space, this is the wrong part, a standard-length two-hole compression lug in the same kcmil range is what you want.
4) Can I use this aluminum lug on copper conductor?
The AL 500 N 32 HS is an aluminum body with tin plating. Tin-plated aluminum compression lugs of this type are rated AL9CU dual-rated in most Blackburn listings, but what is confirmed here is the aluminum barrel, the tin plate and conformance to ANSI C119.4, the standard covering connectors for aluminum and copper conductors. Confirm the AL9CU marking stamped on the barrel against your inspector's requirement before terminating copper.
5) Does this Blackburn lug meet ANSI C119.4 for utility and institutional work?
Yes. The AL 500 N 32 HS is built to ANSI C119.4, the standard for connectors used with aluminum and copper conductors, which is the conformance line most utility, government and institutional specs call out for compression terminations. It is made in the United States.
6) Is this lug insulated?
No insulation. The AL 500 N 32 HS ships bare, so the crimped barrel needs to be covered in the field with heat shrink or tape where phase identification or barrier spacing is required by the installation.
7) What is the manufacturer part number for this Blackburn two-hole lug?
The part number is AL 500 N 32 HS from Blackburn. That is the identifier to quote for the tin-plated aluminum two-hole NEMA straight lug in the 477 to 600 kcmil range with the 32 inch length.
