Blackburn WR259 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR259 H-tap connector accept?
The WR259 is an aluminum H-type compression tap sized for a 1/0 to 2 ACSR run with a 2/0 to 1 tap, per the product designation. It joins two conductors, so it is a single run-to-tap connection, not a multi-tap block. Confirm your run and tap fall inside those ranges before crimping, because a compression tap cannot be re-opened once it is pressed.
2) Is this H-tap insulated, or do I need to cover it after crimping?
No insulation is supplied on the WR259. It presses as a bare aluminum tap, so the joint has to be insulated in the field, typically with a cold shrink or heat shrink tap cover or tape system rated for the operating voltage and for the 90 C conductor rating.
3) Will the WR259 H-tap pass a utility or rural electric spec?
It is RUS Accepted and complies with ANSI C119.4, which is what a rural electric cooperative or utility inspector looks for on a distribution tap connector. That acceptance is the reason this style gets specified on overhead and pad-mount work rather than a generic split bolt.
4) How much room do I need in a pedestal or handhole for this tap?
The WR259 body is 1-7/8 inches long. Add the bend radius of the tap conductor and the length of the insulating cover you plan to install over it when you are figuring clearance inside a pedestal, handhole, or transformer compartment.
5) Should I use an H-type compression tap or a split bolt for tapping a service conductor?
A compression H-tap like the WR259 is pressed with a hydraulic or battery crimp tool and a matching die, giving a permanent, torque-free connection that will not loosen from thermal cycling. A split bolt is mechanical, reusable, and requires torque checks. On aluminum and ACSR distribution taps, where creep under load is the failure mode, the compression tap is what utility specs call for, and this one carries RUS acceptance and ANSI C119.4 compliance. Choose a split bolt only where you need to break the connection later.
6) What temperature is the WR259 compression tap rated for?
Up to 90 C, which lines up with standard 90 C rated conductor insulation such as XHHW-2 and THHN. That makes it suitable for feeders and services run at the 90 C column as long as terminations elsewhere in the circuit carry the same rating.
7) Do I get more than one connector when I order the Blackburn WR259?
The WR259 sells each, so one order line is one connector. Count your taps, and order the die-matched crimp tool and insulating covers separately since neither is included with the connector.
