Blackburn ATL2502 – Frequently Asked Questions
1) What is the advantage of a two-hole lug like the ATL2502 over a single-hole lug?
Two bolt holes stop the lug rotating on the pad. A single-hole lug can spin under fault current or vibration and loosen the joint or shift the conductor; the two-hole pattern locks the tongue flat to the bus or ground bar. The tradeoff is that your landing pad has to have two tapped holes on the correct spacing, so check the pad before you order a two-hole tongue.
2) Is the Blackburn ATL2502 a compression lug or a mechanical set-screw lug?
It's a compression lug. The barrel is crimped onto the conductor with a hydraulic or battery tool and the matching die, so there is no set screw to torque and no re-tensioning later. If you need a termination you can install with a hex key and re-use on a different conductor, you want a mechanical lug instead, not this one.
3) Can I use the Blackburn ATL2502 aluminum lug on copper conductors?
The ATL2502 is an aluminum-bodied compression lug. Aluminum-body compression lugs of this kind are commonly dual rated for aluminum or copper, but the rating that governs is the one marked on the barrel itself, so read the barrel stamp and the die index before you crimp. What the record does state plainly is the body material: aluminum.
4) What part number and manufacturer should I put on the submittal for this two-hole aluminum compression lug?
Specify it as Blackburn ATL2502. Blackburn is the sub-brand label on the part, and ATL2502 is the manufacturer part number stamped on the connector. Country of origin is Mexico, which is the line buyers on federal and institutional jobs usually need for their documentation.
5) Why is this Blackburn lug red, and does the color mean anything on the job?
Red is the color coding on the ATL2502, and on compression connectors that color is a field aid: it lets an inspector or a second installer confirm at a glance that the connector matches the conductor size and the die used to crimp it. It is not a finish or a jacket, and it has no bearing on phase identification.
