Blackburn WR299 – Frequently Asked Questions
1) What wire sizes does the Blackburn WR299 H-tap connector take on the run and the tap?
The WR299 is sized for a 2/0 to 1/0 ACSR main run with a 4 to 6 AWG tap. It joins two conductors, one run and one tap, in a single compression crimp. If your main is larger than 2/0 or your tap is heavier than 4 AWG, you need a different H-tap in the range, not this one.
2) Does the WR299 meet utility specs for distribution work?
Yes. The WR299 complies with ANSI C119.4 and is RUS accepted, which is the pairing most utility and co-op specs call for on compression taps. That makes it usable on RUS-funded distribution jobs where the specification names C119.4 connectors.
3) Is the Blackburn WR299 an aluminum body connector, and can I use it on copper as well as ACSR?
It is an aluminum H-type compression tap sized for ACSR conductors. Aluminum bodies of this kind are normally supplied oxide-inhibitor filled for aluminum and ACSR work. Match the conductor material and size called out for the part, 2/0-1/0 ACSR run with 4-6 tap, rather than substituting a copper conductor into an aluminum-rated tap.
4) What temperature can this H-tap run at once it is energized?
The WR299 is rated for operation up to 90 degrees C, which covers standard 90 C rated conductor installations. Do not apply it where the conductor or the emergency loading takes the joint above that.
5) Does the Blackburn WR299 come insulated, or do I have to cover it after crimping?
It is a bare connector with no insulation on the body. On an energized or covered installation you cover the finished tap yourself, with a cover, tape, or shrink, per your utility or job standard.
6) How long is the WR299 connector body, and will it fit in a tight crimp window?
The body is 1-1/2 inches long. That is the dimension to check against your die length and the working space between the run conductor and any adjacent hardware before you set the crimp.
7) Should I use an H-tap compression connector or a bolted split-bolt for an overhead ACSR tap?
An H-type compression tap like the WR299 is crimped once with a hydraulic tool and die and cannot loosen or be retorqued, which is why utility specs favour it on overhead aluminum and ACSR taps. A bolted split-bolt is reusable and needs no tool, but it needs periodic torque checks and is generally used indoors or on temporary work. Compression is permanent, so size the connector to the conductors before you crimp: 2/0-1/0 ACSR run, 4-6 tap.
8) Is the WR299 sold in bags or individually?
Each. The WR299 is sold as a single connector, so order one per tap you are making rather than by the box quantity.
9) What is the exact part number and who makes the WR299?
Manufacturer part number WR299, made by Blackburn, country of origin Mexico. That MPN is what to quote when matching an existing tap on a line or restocking a truck.
