Blackburn AL 500 N 24 HS – Frequently Asked Questions
1) What conductor size does the Blackburn AL 500 N 24 HS lug take?
The AL 500 N 24 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 tightened with a setscrew. If your feeder is smaller than 477 kcmil, this is the wrong barrel size and the crimp will not hold.
2) Is the Blackburn AL 500 N 24 HS lug aluminum or copper, and can I use it on copper conductor?
It is a tin-plated aluminum body, which is what makes it dual rated in practice for aluminum or copper conductor, and the tin plating is also what lets it land on a copper or aluminum pad without a dissimilar metal problem. The lug meets ANSI C119.4, the standard covering connectors for aluminum and copper conductors.
3) Is this a two-hole NEMA pad lug, and why does that matter for switchgear terminations?
Two-hole NEMA straight tongue, yes. Two bolts on a NEMA drilled pad stop the lug from rotating under fault current or vibration, which is why most gear, panelboard and transformer pads specify a two-hole termination for larger feeders. A single-hole lug on the same pad can spin and back off.
4) Can I install this lug with a wrench, or do I need a crimping tool?
This is a compression connector, so it requires a hydraulic or battery crimp tool with the correct die for the barrel; there is no setscrew to torque. If your crew only carries wrenches, you want a mechanical set-screw lug instead, not this one.
5) What does the 24 inch dimension on this Blackburn lug refer to?
The 24 inch figure is the overall length of the lug, giving a long barrel/extended body run from the crimp to the two-hole pad. That length is what you use when the conductor has to reach a pad set well back in a switchgear or transformer enclosure without a separate splice.
6) Does the Blackburn AL 500 N 24 HS come with insulation or a heat shrink sleeve on it?
No insulation is supplied; the lug ships bare. If the installation calls for a covered termination you will need to add heat shrink tubing or a boot separately, sized to the barrel and conductor.
7) Is the Blackburn AL 500 N 24 HS made in the USA for a Buy American job?
Country of origin on the AL 500 N 24 HS is the United States, which is the record institutional and government buyers usually need for domestic sourcing requirements on electrical material.
8) Is this compression lug sold individually or in a bag of multiples?
Sold each, so a three-phase plus neutral termination means ordering four. Worth counting both ends of the run before you order.
