Blackburn WR839 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR839 H-tap connector take?
The WR839 is sized for a 477 or 556 run conductor with a 336 tap, per the product designation AL HTYPE COMP CONN 477-336 556-336. It is an aluminum H-type compression tap, so it joins two conductors, a main run and a tap, in one crimp. Match your actual conductor size and stranding to those ratings before crimping; an H-tap outside its size range will not compress to a sound connection.
2) Can I install the WR839 tap with a mechanical wrench, or do I need a crimp tool?
This is a compression connector, not a bolted or set-screw tap. It has to be crimped with a hydraulic or battery compression tool using the die called out for the connector. If your crew works with hand wrenches only, you want a bolted split-bolt or mechanical tap instead.
3) Is the WR839 H-tap rated for 90 degree C conductors?
Yes. The WR839 compression tap is rated for operation up to 90 degrees C, which covers standard 90 C rated aluminum and copper-clad overhead and underground conductors. It also complies with ANSI C119.4 and is RUS accepted, which is what utility and co-op specs typically call for on connectors.
4) Does the Blackburn WR839 come insulated or do I need to cover it?
It ships bare. The WR839 has no insulation on the connector body, so any dielectric protection, tape, a cover, or a shrink boot has to be added separately on energized or exposed work.
5) How long is the Blackburn WR839 connector body?
The body measures 2 inches in length. That matters when you are fitting a tap into a tight pedestal, hand hole, or crossarm space, and when you are stripping conductor, since the full barrel length has to be crimped.
6) Is the WR839 sold individually or in a box quantity?
It is sold each, one connector per unit, under manufacturer part number WR839. Order the count you need for the job rather than a carton quantity.
7) Where is the Blackburn WR839 made?
The WR839 aluminum H-tap is manufactured in Mexico. Buyers with domestic-content requirements on a funded project should confirm that against their own procurement rules.
