Blackburn WR879 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR879 H-tap connector take?
The WR879 is sized for a 477 to 336 run conductor with a 336 to 266 tap. Both are aluminum ranges, so match the ACSR/AAC size on your run and tap before crimping. It handles two conductors, one run and one tap, in a single H-shaped compression body.
2) Can I use an aluminum H-tap like the WR879 on copper conductors?
No. The WR879 is an aluminum body H-tap intended for aluminum run and tap conductors in the 477-336 / 336-266 range. For copper-to-copper or mixed copper-aluminum taps you need a connector rated for those combinations, not this one.
3) Does the Blackburn WR879 meet utility spec for distribution work?
It is RUS Accepted and complies with ANSI C119.4, which is the standard covering connectors for underground and aboveground conductor connections. That is the spec most utilities and co-ops cite on a tap connector submittal.
4) What operating temperature can this compression tap connector handle?
Rated for conductor operating temperatures up to 90 degrees C, which lines up with standard 90 C rated distribution and building conductors.
5) Is the WR879 H-tap insulated, or do I have to cover it after crimping?
It ships bare, with no insulation on the body. If the tap needs to be covered, plan on a separate insulating cover, tape, or shrink kit as part of the job.
6) Is the WR879 a bolted tap or does it need a crimp tool?
Compression only. It is installed with a hydraulic or battery crimp tool and the correct die for the connector, not with a wrench. If you want a connection you can open later for testing, a bolted or wedge-type tap is the better choice; compression H-taps are permanent.
7) How long is the Blackburn WR879 connector body?
The body measures 3 inches in length, so allow that much parallel conductor overlap plus working room inside the enclosure, handhole, or on the pole before you set the crimp.
8) Is the WR879 sold in bags or individually?
It sells each, so order one connector per tap you are making. For a run of splices, count taps and add spares for miscrimps.
