Burndy YA25A7 – Frequently Asked Questions

1) What wire size does the Burndy YA25A7 lug take, and can I use it on aluminum conductor?
The YA25A7 HYLUG is sized for 1/0 AWG stranded conductor, and it's dual rated for both copper and aluminum. One barrel size only, so it is not a range-taking lug; 2 AWG or 2/0 conductor needs a different YA part.
2) What die do I need to crimp a Burndy YA25A7?
Die Index 296, identified by the tan color code stamped on the lug. Match the tan die marking in your Burndy hydraulic or battery crimper set; the color code is there so you can verify tool and die at the connection rather than guessing from the part number.
3) Is the Burndy YA25A7 UL Listed, and to what standard?
Yes, UL Listed to UL468A-468B, the standards covering wire connectors. Note that CSA approval, ETL, cULus and UL Recognized are all marked No on this part, so if your job requires a CSA mark for Canadian work this is not the lug for it.
4) Will an aluminum body lug work on copper conductor without causing corrosion?
Yes. The YA25A7 is a dual rated AL/CU lug, and the aluminum body is electro tin plated, which is what puts a compatible surface between the aluminum lug and copper conductor or a copper bus. Tin plating is also what gives it corrosion resistance in damp or outdoor gear.
5) How much insulation do I strip back for this compression lug?
Strip length is 1-1/16 in, which matches the barrel depth (B length 1.05 in). Strip to that and the conductor bottoms out in the chamfered barrel with no bare copper or aluminum showing past the crimp.
6) What voltage and temperature is this HYLUG rated for?
600V minimum rating with a 35 kV (35,000V) maximum, so it covers everything from service entrance and panel work up through medium-voltage terminations. Temperature rating is 194 degrees F.
7) Why use a two-hole lug instead of a one-hole on a ground bar or equipment pad?
Two bolts keep the lug from rotating under load or vibration, which is why two-hole pads are the norm on bus bars, ground bars and equipment terminals. The YA25A7 has a two-hole pad with a straight tongue angle, meaning the pad runs in line with the barrel rather than offset or bent, so plan your conductor approach square to the pad.
8) How much room do I need behind the pad to land this lug?
Overall length is 4.59 in (117 mm) with a barrel outside diameter of 0.60 in. Allow for that full length plus the conductor bend radius when you're landing it in a tight gutter or a shallow equipment enclosure.
