Blackburn WR189 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR189 H-tap connector accept?
The WR189 is sized for a 2/0 through 1/0 ACSR run conductor with a 2 through 6 tap. It's a two-conductor connector, so one run and one tap per crimp. If your run is larger than 2/0 or the tap is bigger than #2, you need a different catalog number in the H-tap series.
2) Is the Blackburn WR189 tap connector installed with a crimp tool or a bolt?
It's a compression connector, not a bolted tap. The H-shaped aluminum body is crimped over the run and tap with a hydraulic or battery compression tool using the matching die. There is no hardware to torque and no way to re-open the joint once it's crimped, so conductor placement has to be right before you press it.
3) Does the WR189 H-tap meet utility specs for overhead distribution work?
The WR189 is RUS Accepted and complies with ANSI C119.4, which is the standard covering connectors for use with aluminum and copper conductors. That's the pairing most co-ops and municipal utilities call out on a tap connector submittal.
4) Is the Blackburn WR189 insulated, or does it need covering after crimping?
Bare aluminum, no insulation on the body. Any covering the job requires, such as a shrink or cold-shrink tap cover or tape buildup, is a separate item you order alongside it.
5) What temperature is the WR189 aluminum H-tap rated to?
Rated for operation up to 90 degrees C, which matches the continuous rating of common 90 C cable insulation systems. Conductor emergency ratings above that are outside what this connector is listed for.
6) How long is the Blackburn WR189 H-tap body, and will it fit in a tight space?
The body measures 1-11/16 inches in length. That is the dimension to check against your available spacing between the pole hardware and adjacent phases, and it also tells you how much clear conductor you need to strip and brush before crimping.
7) Can I use the WR189 to tap a copper conductor off an aluminum run?
The WR189 is an aluminum H-tap sized for ACSR run conductor. For a copper-to-aluminum transition you want a connector specifically listed for dual-rated or bimetallic service; ANSI C119.4 compliance covers connector performance but does not by itself make this the right part for mixing metals.
8) Is the Blackburn WR189 sold individually or in a box?
Sold each, one connector per unit, under manufacturer part number WR189. Order the quantity of taps the job calls for; there is no fixed carton count applied to the selling unit.
