Blackburn AL 1250 NGSH – Frequently Asked Questions
1) What conductor size does the Blackburn AL 1250 NGSH lug take?
The AL 1250 NGSH is sized for 1250 kcmil conductor. It is a compression lug, so it is crimped onto the cable rather than set-screwed, and there is one conductor barrel per lug. If your feeder is a different kcmil size, you need the matching size in the series, not this one.
2) Is the AL 1250 NGSH a one-hole or two-hole lug?
Two-hole. It is a two hole compression lug, so it bolts to a pad with two fasteners and resists rotating under torque, which is what most switchgear and busbar pads are drilled for.
3) How much room do I need in the gutter or termination compartment for this 1250 kcmil lug?
Plan on a footprint of 9-11/16 inches long by 2-21/32 inches wide for the AL 1250 NGSH. At that length, check bending space and barrel clearance in the cabinet before you commit, especially where several 1250 kcmil terminations land side by side on the same pad.
4) Does the Blackburn AL 1250 NGSH meet a connector standard for specification work?
It is built to ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors. That is the reference to put on a submittal when the spec calls for a listed compression connector.
5) Is this lug insulated, or do I need to cover the termination myself?
Bare. The AL 1250 NGSH has no insulation on the barrel or tongue, so any covering, heat shrink, or boot at the termination has to be ordered separately and applied after crimping.
6) Can I use a compression lug like this instead of a mechanical set-screw lug on a 1250 kcmil feeder?
Yes, and on conductors this large compression is the common choice. A compression lug is crimped once with a die and hydraulic tool, so there is no torque to re-check and no set screw to back off under thermal cycling. The trade-off is that it is permanent and you must have the correct tool and die on site. Mechanical lugs make sense when you need a field-adjustable or reusable termination.
7) Are Blackburn AL 1250 NGSH lugs sold individually or in packs?
Each. The selling unit is a single lug, so for a three-phase feeder with a neutral you would order four, one per conductor termination.
8) Where is the Blackburn AL 1250 NGSH made? We have domestic-content requirements.
Manufactured in the United States. That matters on federal, municipal, and institutional jobs carrying domestic sourcing language, and it is the country of origin to cite on the submittal.
