Blackburn WR399 – Frequently Asked Questions

1) What conductor sizes does the Blackburn WR399 H-tap take on the run and the tap?
The WR399 is sized for a 4/0 to 3/0 ACSR main line with a 2/0 to 1 AWG tap. Both conductors seat in the same H body and get compressed together, so the run and tap ranges are not interchangeable. If your tap is heavier than 2/0 or your run is smaller than 3/0 ACSR, this is the wrong connector in the series.
2) Is the Blackburn H-tap a bolted connector or does it need a compression tool?
Compression only. There is no bolt or set screw on the WR399 H-tap, so it takes a hydraulic or battery compression tool with the correct die for the body. Once crimped it is a permanent connection, which is why utilities use it on overhead distribution rather than a bolted split bolt you can take apart later.
3) Does this Blackburn H-tap meet utility spec for a rural co-op job?
It is RUS accepted and complies with ANSI C119.4, which is the connector standard utilities write into distribution specs. That covers it for rural electric cooperative and overhead line work where the drawing calls out a C119.4 compression tap.
4) Can I use the WR399 H-type tap on insulated cable or in a wet underground splice?
No. The WR399 ships bare with no insulation on the body, so any connection you make with it has to be insulated or covered separately, or left open on an overhead line where air is the insulation. It is not a submersible or direct-bury splice assembly.
5) What temperature can this compression tap run at?
Rated up to 90 degrees C. That matches the usual 90 C conductor rating on distribution work, so it will not be the limiting element on a line loaded to conductor temperature.
6) How much room do I need on the conductor to fit this H-tap?
The body is 2-3/16 inches long, so you need a clear run of at least that much plus your tool jaw clearance on the line. Short enough to work in a crowded enclosure or between existing taps.
7) How many conductors go into one Blackburn WR399?
Two, one run and one tap. It is a 2-conductor H body, not a multi-tap block, so a second tap off the same point means a second connector.
8) Is the WR399 sold individually or in a box quantity?
Sold each, so you can order the exact count for the job rather than a carton. Country of origin is Mexico.
9) Does this H-tap mount to a pole or panel?
No mounting provision at all. The WR399 is carried entirely by the conductors it crimps onto, so there is no bracket, stud, or panel hole. Plan the connection where the line can support it.
