Blackburn AL 500 NRTN – Frequently Asked Questions
1) What wire size does the Blackburn AL 500 NRTN compression lug take?
The AL 500 NRTN is sized for 500 kcmil conductor. It is a compression connector, so the barrel is crimped onto the cable with a die-type tool rather than tightened with a set screw. Barrel length is 2.563 inches and overall length is 5.815 inches.
2) Will the two-hole pad on this 500 kcmil lug land on my bus bar?
The pad measures 1.750 inches wide, with 4.125 inches from the end of the pad to the side of the barrel. It is a two-hole pad, so it will not rotate under torque once both bolts are set, which is why utilities and switchgear specs call for two-hole on large feeders. Check your bus hole spacing and pad width against those numbers before you drill.
3) Can I use an aluminum compression lug like the AL 500 NRTN on copper conductor?
The AL 500 NRTN is a tin plated aluminum body lug. Tin plating is what makes an aluminum barrel suitable for dual-rated aluminum or copper use on many products, but the rating that governs that is printed on the connector and its die chart, so match the lug marking and die to the conductor you are terminating. The tin plating also keeps the pad from galvanic corrosion where it bolts to a copper or plated bus.
4) Does this compression lug come insulated or do I need to tape and boot it?
It ships bare. There is no insulation on the AL 500 NRTN, so the barrel and pad need covering in the field where required, typically heat shrink or a molded boot sized for a 500 kcmil lug barrel. Plan the boot into the order if the enclosure or the inspector calls for it.
5) Are Blackburn AL 500 NRTN lugs sold individually or in bags?
Sold each. Count one per conductor termination, so a three-phase 500 kcmil feeder with neutral needs four, and add for the ground if it is being landed on a lug of its own.
6) Is the Blackburn AL 500 NRTN made in the USA for a government or Buy American job?
Country of origin on the AL 500 NRTN is the United States, which is what a federally funded or Buy American-spec project will ask you to document at submittal.
