Blackburn GLE 300 N AL 2 Hole Lug 300

The GLE 300 N is sized for 300 kcmil conductor. It is a compression lug, so the barrel is crimped onto the cable with a die, not bolted or set-screwed. If your cable is a different size, you need the matching GLE part for that kcmil rating, not this one.

The GLE 300 N is an aluminum-body lug, bare (unplated) finish, supplied as a two-hole compression lug for 300 kcmil. Aluminum-body compression lugs of this style are commonly used on aluminum conductor; if your run is copper and your spec calls for a copper or dual-rated barrel, order the corresponding copper lug instead of substituting this one.

It is a CSA-die compression lug, so it is crimped with the CSA die index for the 300 kcmil barrel in your hydraulic or battery crimper. Set the tool to the CSA index called out for 300 kcmil and make the number of crimps the die chart specifies. Do not substitute a different die index family, an undersized crimp on a 300 kcmil barrel will not hold pull-out or meet the connector standard.

Testing is to ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper conductors. That is the reference most utility and commercial connector specs cite for compression connectors, so the GLE 300 N can be submitted against it directly. It is also made in the United States, which matters on Buy American jobs.

Two-hole is the right call anywhere the connection can see vibration or cable torque, because the second bolt keeps the pad from rotating on the bus or panel landing. The GLE 300 N is a two-hole pad. Use a one-hole lug only where the pad drilling on your bus or breaker lug landing has a single tapped hole. Match the hole spacing and bolt size on the equipment before you crimp anything, since a two-hole pad will not land on single-hole prep.

Overall length is 6 inches. That is a long barrel, so check the bending space and gutter depth where the cable lands before committing, especially in a shallow enclosure or a tight pull box. In a full-size switchboard or CT cabinet it is not an issue.

No insulation is supplied, the barrel and pad are bare. On any installation where the terminated barrel is inside a live compartment or close to grounded metal, you will need to add your own insulating boot or tape wrap to keep the required clearance. Factor that into your material list, it is not included.

No. A compression lug is a permanent termination, the barrel is deformed onto the conductor by the die and cannot be opened and re-crimped. If you cut the cable back, order a new GLE 300 N. Where you need a reusable termination, use a mechanical set-screw lug instead of a compression lug.

The GLE 300 N sells individually, each. Handy when you only need to replace one termination, and it also means you should count your terminations (two ends of every conductor, plus spares for a miscrimp) when you build the order for a full feeder.
