Blackburn WR989 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR989 H-tap connector accept on the main and tap?
The WR989 takes 900 through 600 kcmil stranded on the main run and 900 through 600 kcmil stranded on the tap, so both legs cover the same range. It is a two-conductor connector: one main, one tap. If either of your cables falls outside 600 to 900 kcmil stranded, this is the wrong die size and you need a different H-tap.
2) Does the WR989 H-tap meet utility specs for a distribution or substation 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 underground and distribution applications. That is the pairing most utility and co-op material specs call for on a compression tap.
3) Is this a bolted tap or does it need a crimp tool?
Compression only. The WR989 is installed with a hydraulic crimper and the matching die set for the H-tap body, not with a wrench. If you need a connection you can take apart later for testing or load transfer, use a bolted split-bolt or mechanical tap instead.
4) Is the Blackburn WR989 an aluminum body tap, and can I use it on copper?
The WR989 is an aluminum H-type compression tap. Aluminum bodied taps of this style are commonly filled and rated for aluminum-to-aluminum and aluminum-to-copper combinations, but the WR989's own record states only the aluminum body and the 900 to 600 kcmil stranded range for main and tap. If your job is copper to copper, confirm the conductor combination against the die chart before you crimp.
5) What temperature is the Blackburn WR989 tap rated for?
Rated for operation up to 90 degrees C, which lines up with 90 C rated cable insulation on the conductors it joins. Do not use it on a circuit where the conductor operating temperature exceeds that.
6) Does the WR989 come insulated, or do I have to cover it after crimping?
It ships bare, with no insulation on the connector body. Plan on covering the completed tap yourself, typically with a heat shrink or cold shrink tube, a mold-in-place kit, or tape, sized to clear the finished crimp on 600 to 900 kcmil cable.
7) How much room do I need in the enclosure or handhole for a WR989 H-tap?
The connector body is 4-3/4 inches long, and that is before you add cover material. Allow for the full length plus the bend radius of two 600 to 900 kcmil cables when you are laying out a pedestal, handhole, or gutter.
8) Is the Blackburn WR989 sold individually or by the box?
Sold each, one connector per unit, so order the exact count of taps your splice plan calls for. Buy your cover kits separately since the connector ships uninsulated.
