Blackburn WR819 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR819 H-tap connector take on the run and the tap?
The WR819 is sized for a 477 through 336 ACSR main run with a 2/0 to 3 AWG tap. It is a two-conductor H-type tap, so one run and one tap per connector. If your main is outside the 477 to 336 range, or the tap falls outside 2/0 to 3, you need a different H-tap size in the series.
2) Is the Blackburn WR819 a bolted tap or does it need a compression tool?
It's a compression connector, not bolted. Installation is with a hydraulic or battery compression tool and the correct die for an H-tap body; there are no bolts or set screws to torque. Body length is 2 inches, so plan crimp positions and conductor slack for that footprint.
3) Does the Blackburn WR819 meet ANSI C119.4 and is it accepted for RUS utility work?
Both. The WR819 complies with ANSI C119.4 and is RUS Accepted, which is what utility and co-op specs typically call for on compression taps. Rated for service up to 90 degrees C.
4) Can I use the WR819 H-tap on aluminum ACSR overhead conductor?
Yes. The WR819 is an aluminum H-type compression tap intended for ACSR main conductors in the 477 to 336 range, which is the standard overhead distribution application for this body style.
5) Is the WR819 insulated, or do I have to cover the tap after crimping?
It is a bare connector with no insulation. On energized or exposed work you cover it yourself, with tape, a cover, or shrink, per your utility's practice. Nothing insulating ships with the connector.
6) Will the WR819 hold up at 90 C conductor temperature on a loaded feeder?
Yes, the connector is rated for operation up to 90 degrees C, and its ANSI C119.4 compliance covers the current-cycling and mechanical performance a tap connection sees on a loaded line.
7) What is the exact Blackburn part number to order for a 477-336 ACSR run with a 2/0 tap?
Blackburn WR819. That is the manufacturer part number for the aluminum H-type compression tap covering 477 to 336 ACSR main with 2/0 to 3 tap.
8) How is the Blackburn WR819 sold, individually or in a box?
Sold each. One WR819 H-tap per unit, so order the exact count of taps your job needs plus spares for miscrimps. Country of origin is Mexico.
