Blackburn WR949 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR949 H-tap connector take on the run and the tap?
The WR949 is sized for a 795 through 477 main run with a 336 through 1/0 tap. It is a two-conductor H-type connector, so one run and one tap per fitting.
2) Is the WR949 an aluminum connector, and can I use it on aluminum overhead conductor?
Yes. The WR949 is an aluminum H-type tap connector, which is what you want for aluminum-to-aluminum run and tap splices on distribution and service conductors. Nothing in the data covers use on copper, so treat it as an aluminum-body compression fitting.
3) Does the Blackburn WR949 meet ANSI C119.4, and is it accepted for RUS work?
Both. The WR949 complies with ANSI C119.4 and is RUS Accepted, which is the box utility and co-op specs usually require for a compression tap. It is rated for operation up to 90 degrees C.
4) Do I need a crimp tool for the WR949, or can it be bolted on?
It is a compression fitting, not a mechanical bolted tap. You crimp it with a hydraulic or battery compression tool and the correct die per the manufacturer's die chart. If you want a connector that goes on with a wrench instead, look at a bolted H-tap or a wedge connector rather than this one.
5) My tap is smaller than 1/0 or my run is bigger than 795, is the WR949 still the right H-tap?
No. The WR949 only covers 795 to 477 on the run and 336 to 1/0 on the tap. Outside that window the crimp will not compress correctly, so move to another WR-series H-tap sized for your actual run and tap combination.
6) Is the WR949 insulated, and does it need to be covered after crimping?
No insulation is supplied with it. The WR949 is a bare aluminum compression body, so any covering or re-insulation on the splice, tape, mastic, or a cover, has to be handled separately as part of your installation.
7) How long is the Blackburn WR949 connector body?
Length is 4-3/4 inches. Worth checking against your working space if you are tapping in a tight crossarm or pedestal, since the crimp tool jaws need room on top of the body length.
8) Is the WR949 sold by the each or in a bag?
Sold each, model WR949. Order one per tap you are making.
