Blackburn L250H – Frequently Asked Questions

1) What wire range does the Blackburn L250H mechanical lug take?
The Blackburn L250H accepts a single conductor in the 6 AWG through 250 MCM range, stranded. One conductor per lug, so a branch circuit that needs two runs landed needs either two lugs or a two-conductor body.
2) Can I use the L250H with aluminum conductors, or is it copper only?
Both. The lug body is copper, and it is rated for aluminum conductors as well, which is what the AL/CU hex designation in the L250H description covers. On aluminum, brush and apply an oxide inhibitor before landing the conductor per normal practice.
3) Is the Blackburn L250H UL listed for panel and service equipment work?
Yes. It carries UL file E9809, which is what an inspector looks for on a mechanical lug landing a feeder in a panel, gutter, or utility connection point.
4) How does the L250H mount, and how many bolt holes does it have?
One-hole mount. A single bolt or stud secures the lug pad to the bus or ground bar, which keeps the footprint small but means the lug can rotate under torque until the bolt is fully tight. If your bus prep has two holes on a fixed center, you need a two-hole lug instead.
5) Do I need a crimp tool or die set for the L250H?
No. It is a mechanical connector, tightened with a hex socket or Allen wrench on the setscrew, so no crimper, die set, or hydraulic tool is required. That makes it the usual choice for field terminations and MRO repairs where a compression tool is not on the truck.
6) Should I use a mechanical lug like the L250H or a compression lug on a 250 MCM feeder?
A mechanical lug is the practical pick when you are working in place, may need to re-terminate later, or do not want to carry a hydraulic crimper and 250 MCM dies. It installs with a wrench and can be removed. A compression lug gives a permanent one-shot termination and is preferred where vibration or spec calls for it. For panel connections, wire management, and maintenance work, the L250H covers it.
7) Is the L250H sold individually or in a bag of multiples?
Sold each, one lug per unit. Order the quantity you need, counting one lug per conductor being landed.
8) Where is the Blackburn L250H made?
Mexico. Relevant if you are bidding work with domestic-sourcing or country-of-origin documentation requirements on the submittal.
