Blackburn GLE 350 ALUM SPLICE FOR 350 CANADA

The GLE 350 is sized for 350 kcmil aluminum conductor, which is what the 350 in the model designation refers to. It joins two conductors, so it is a straight inline splice rather than a tap or multi-port connector. If your run is a different kcmil size, you need the matching GLE number instead, since a compression splice only crimps correctly on the conductor size it was built for.

Compression. The GLE 350 is crimped with a die-type compression tool, not tightened with set screws, so you need the correct hydraulic or battery crimper and die for the barrel. Mechanical set-screw splices are the alternative when you do not have a crimper on site, but they are a different part. Nothing about the GLE 350 can be installed with a hex key.

It ships bare, with no insulation on the barrel. Aluminum, uncoated finish. That means the installer supplies the covering: heat shrink, a cold shrink tube, or tape build-up appropriate to the circuit voltage. Plan for that material on the job, because a bare splice left uncovered on a service entrance conductor is not a finished installation.

Overall length is 4 inches. Add the length of whatever insulating cover you put over it plus bending room for two 350 kcmil conductors when you check clearance in a pull box, meter can, or handhole. A 350 kcmil aluminum conductor has a large bending radius, so the box, not the splice, is usually the limiting factor.

It is an aluminum splice, listed for 350 aluminum conductor. Do not treat it as a copper-to-aluminum transition unless the connector is marked AL9CU for dual-rated use. For joining copper to aluminum you want a connector specifically rated for both metals, otherwise you risk a dissimilar-metal connection in a service entrance.

The GLE 350 is built to ANSI C119.4, the standard covering connectors for use between aluminum and aluminum or aluminum and copper conductors. If a utility spec or an inspector on a service entrance job asks for a C119.4 connector, this designation is what they are asking for. Country of origin is the United States.

No. The GLE 350 accepts two conductors in line, so it makes a straight splice between two ends of the same size run. For pulling a smaller tap off a larger feeder you need a reducing tap connector or an H-tap, not this barrel.

Sold each. One splice per unit, so order one per joint you are making. For a three-phase service with a neutral you would be ordering four, plus whatever insulating material you cover them with.
