Blackburn WR719 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR719 H-tap connector take on the run and the tap?
The WR719 is sized for a 397.5 to 266.8 ACSR main run with a 2/0 to 3 conductor tap, which is what the 397-266ASCR 2/0-3 marking on the connector means. It is a two-conductor connector, one run and one tap, so it makes a single tap off a main line.
2) Is the Blackburn WR719 a compression connector or a mechanical bolted tap?
It is a compression H-tap, not a bolted or set-screw connector. You crimp it with a hydraulic tool and the correct die for the body, so there is nothing to re-torque later. If your crew is not carrying a compression tool on the truck, a mechanical wedge or bolted tap is the better choice for that job.
3) Can I use the WR719 aluminum H-tap on copper conductors?
The WR719 is an aluminum-body H-tap intended for aluminum and ACSR conductors. Copper-to-aluminum transitions need a connector rated for dual metals, so specify a bimetallic or AL9CU-marked tap instead of this one where a copper conductor is involved.
4) Does the WR719 meet ANSI C119.4 and is it accepted for RUS work?
Yes on both counts. The WR719 complies with ANSI C119.4 specifications and is RUS Accepted, which is what utility and rural electrification jobs ask for on a tap connector.
5) What temperature is this aluminum compression tap rated for?
Rated for operation up to 90 degrees C, so it suits 90 C rated conductor systems. Above that rating you need a connector specified for the higher temperature.
6) Is the Blackburn WR719 insulated, or do I need to cover the connection?
It is a bare connector with no insulation, so the completed tap has to be insulated or covered in the field where the application calls for it, typically with a suitable cover or tape system. Bare bodies are normal for overhead and enclosure taps.
7) How long is the WR719 connector body, and how many crimps does that mean?
The body measures 2 inches in length. Plan your working space and die spacing around that, and follow the crimp count marked on the connector body for the die you are using.
8) Is the Blackburn WR719 sold individually or in a bag?
Sold each, so order the exact quantity of taps you need for the job rather than a fixed carton. Part number is WR719.
