Blackburn L250P – Frequently Asked Questions
1) What wire sizes does the Blackburn L250P mechanical lug accept?
The L250P is built for a single conductor in the 6 STR through 250 kcmil range, which is what the "6STR-250" in the part description refers to. It takes one conductor per lug, so parallel runs need one lug per conductor.
2) Is the Blackburn L250P suitable for aluminum conductors or copper only?
Copper only. The lug body is copper, tin-plated, and the "CU" designation in the part description means it is rated for copper conductors. For aluminum or dual-rated AL/CU work you need a lug marked AL9CU.
3) How does the Blackburn L250P mount to a panel or ground bar?
One-hole mount, single conductor. You get a single bolt hole through the lug pad, so it lands on a flat surface, bus, or ground bar with one fastener. Mounting hardware is not part of the lug itself; supply the bolt, washers, and nut to suit the pad and the surface you are landing on.
4) Is this a compression lug or a mechanical set-screw lug?
Mechanical. The L250P is a set-screw type mechanical connector, so it is installed with a hex key or driver to the specified torque and needs no crimp tool or die set. If your spec calls for a compression lug, this is not a substitute.
5) Why is the L250P tin-plated instead of bare copper?
Tin plating over the copper body slows oxidation on the contact surface and at the bolted pad, which matters in damp, outdoor, or corrosive environments and where the lug bolts to a dissimilar metal surface. Electrically it behaves as a copper connector.
6) Is the Blackburn L250P sold individually or in a bag of multiples?
Sold each. One lug per unit, so order the exact count of terminations you need rather than by bag or box.
7) What is the exact part number and origin for submittal paperwork on this Blackburn lug?
Blackburn manufacturer part number L250P, made in Mexico. That, with the UL E9809 file reference, is normally what a submittal package needs for a mechanical copper lug.
