Blackburn WR999 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR999 H-tap connector take?
The WR999 is sized for a 954-666 main run with a 654-666 tap, which is the size combination printed on the connector body. Both conductors seat in the same die-crimped H body, so match your cable to those ranges before crimping; an undersized conductor in an oversized H-tap will not develop a sound compression joint.
2) Is the Blackburn WR999 for aluminum conductors or copper?
It is an aluminum H-type compression tap connector. Aluminum bodies of this style are normally used on aluminum-to-aluminum runs; for a copper tap you want a connector rated for that combination rather than this one.
3) Does the WR999 H-tap meet utility spec for a distribution tap?
It is RUS Accepted and complies with ANSI C119.4, which is the standard covering connectors for use between aluminum and copper conductors in distribution and transmission. That is typically what a utility or municipal spec calls out for a compression tap.
4) What temperature can this Blackburn compression tap run at?
Rated for conductor operating temperatures up to 90 C, so it suits 90 C rated cable such as XHHW-2 aluminum feeders without derating the connector.
5) Does the WR999 come insulated, or do I have to tape or boot it?
Bare metal, no insulation on the connector. Any insulating or re-jacketing of the finished tap has to be done in the field with tape, a cover, or a shrink boot ordered separately.
6) How long is the Blackburn WR999 H-tap body?
4-3/4 inches long. That matters in a tight pedestal, handhole, or gutter, since you need room for the connector plus the crimp head to swing around it.
7) Can I use a mechanical setscrew tap instead of this compression H-tap?
Different tools, different joint. The WR999 is a compression connector, crimped with a hydraulic tool and the correct die, and it gives a permanent joint that meets ANSI C119.4. A mechanical setscrew tap installs with a wrench and can be taken apart later, which is why crews pick it for temporary or serviceable connections. Pick compression when the spec calls for a permanent, non-reenterable tap.
8) How many wires does one WR999 connector join?
Two conductors, one run and one tap, in a single H body. For a second tap off the same run you need a second connector and enough clear cable to crimp it.
9) Is the Blackburn WR999 sold individually or in a bag?
Sold each, so the count you order is the count of connectors you get. Order one per tap point and a spare or two, since a miscrimped H-tap cannot be reused.
