Blackburn WR369 AL HTYPE COMP CONN 4/0-3/0ASCR 1-3

The WR369 is sized for a 4/0 ACSR run conductor with a 3/0 ACSR tap, per the product designation 4/0-3/0 ASCR. It joins two conductors, a main and a tap, in a single H-shaped compression barrel. If your run or tap falls outside those sizes, you need a different H-tap in the series, since compression connectors are die and size specific and will not grip properly on an undersized or oversized conductor.

It is a compression-only connector. The WR369 is installed with a hydraulic or battery compression tool and the correct die, not with a wrench. There are no bolts, set screws, or shear heads on it. If you want a connection you can take apart later for testing or re-tapping, a bolted split-bolt or a mechanical tap is the right choice instead, because a compressed H-tap is permanent.

It is RUS Accepted and complies with ANSI C119.4 specifications, which is the standard covering electric connectors for use between aluminum and copper conductors. That combination is what utility and co-op specs typically call for on distribution taps, so it will generally satisfy a drawing that names C119.4.

Bare aluminum, no insulation on the body. Any covering, tape, heat shrink, or a molded tap cover is field-applied and ordered separately. Overhead and enclosure work where the tap stays bare is the usual application; if the tap sits where it can be contacted or where you need dielectric integrity, plan the cover into the job.

Rated for service up to 90 degrees C, which lines up with the 90 C conductor insulation systems used on most commercial and utility feeders. Keep continuous operating temperature at or under that figure when you size the tap.

The connector body measures 1-7/8 inches in length, so that is the barrel run you need clear along the conductor, plus tool clearance on either side for the compression head to close. On tight pedestal or riser work, check the head swing before you strip the conductor.

The WR369 is an aluminum-body H-tap built for ACSR conductors in the 4/0 run and 3/0 tap sizes. Its compliance with ANSI C119.4, the standard for connectors used between aluminum and copper conductors, is what governs mixed-metal use; follow the conductor combination the connector is listed for and use the correct oxide-inhibiting compound on aluminum. For an all-copper tap, specify a copper compression tap sized to those conductors instead.

Sold each, one connector per unit, so order the exact count of taps your job needs rather than a carton quantity. Each piece carries the Blackburn part number WR369 and is made in Mexico.
