Blackburn WR799 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR799 H-tap connector take?
The WR799 is sized for a 477 to 266 ACSR run conductor with a 4 to 6 tap. That pairing is what the catalog designation 477-266ASCR 4-6 refers to, and it is a two-conductor connector: one run, one tap. If your run or tap falls outside that range, you need a different H-tap in the series.
2) Is the WR799 H-tap an aluminum body, and can I use it on copper?
It is an aluminum H-type compression tap connector, called out as AL in the Blackburn designation, and it is built for the aluminum ACSR sizes in its range. Treat it as an aluminum-to-aluminum tap; for copper runs or copper-to-aluminum transitions, use a connector rated for that combination.
3) Does the Blackburn WR799 meet ANSI C119.4 and is it accepted for RUS jobs?
Yes on both counts. The WR799 complies with ANSI C119.4 specifications for connectors used on aluminum and copper conductors, and it is RUS Accepted, which matters on rural utility and co-op work where RUS acceptance is a bid condition.
4) What temperature is this H-tap connector rated for?
Up to 90 degrees C. That covers standard 90 C rated conductor operation, so the tap is not the limiting element on a typical 90 C rated overhead or service run.
5) Do I need a special crimp tool for the WR799 tap connector?
This is a compression connector, not a bolted or set screw tap, so it goes on with a hydraulic or battery compression tool and the die specified for the connector. There is no mechanical torque option on it. Plan the tool and die into the job before you get to the pole or the pedestal.
6) Is the WR799 insulated, or do I have to cover it after crimping?
It ships bare, with no insulation on the body. Any covering, whether tape, a cover kit, or heat shrink, has to be added in the field if the installation calls for it.
7) How long is the Blackburn WR799 connector body, and how is it sold?
The body measures 2 inches in length, which is the figure to check against your available working space on a tight tap or inside a pedestal. It is sold individually, each, rather than in a bag or carton quantity.
8) What is the exact manufacturer part number for this Blackburn H-tap?
Blackburn WR799. That is the full catalog number for the aluminum H-type compression tap covering 477-266 ACSR run with 4-6 tap, and it is manufactured in Mexico.
