Blackburn WR399L – Frequently Asked Questions
1) What is a Blackburn WR399L H-tap connector used for?
The WR399L is an H-type compression tap connector, used to join a tap conductor to a run conductor in a permanent, non-reversible crimp. It handles two conductors, one run and one tap, and is crimped with a compression tool rather than bolted, so once it is pressed it stays put. It is sold individually, each.
2) Does the Blackburn WR399L come insulated, or do I have to cover it after crimping?
It ships bare, with no insulation on the connector body. Any insulating or re-jacketing at the tap, tape, a cold shrink, or a mold-on cover, is a separate item you need to add to the job if the application calls for it.
3) Does the Blackburn WR399L meet ANSI C119.4 for utility work?
Yes. The WR399L complies with ANSI C119.4, the standard covering connectors for underground and overhead distribution conductors, and it is RUS accepted, which is what utility and rural electric co-op specs typically call for on tap connectors.
4) What temperature is the WR399L H-tap rated to, and can I use it on 90 degree C rated cable?
Rated up to 90 degrees C, so it matches conductors with 90 degree C rated insulation such as THHN/THWN-2 or XHHW-2. Running it above that rating is outside what the connector is listed for.
5) How long is the Blackburn WR399L H-tap body?
The barrel is 2-1/2 inches long. That length matters for die selection and crimp count, and for making sure you have clearance in the enclosure, handhole, or pedestal where the tap lands.
6) Can I install a WR399L H-tap with a manual crimper or do I need a hydraulic tool?
It is a compression connector, not a mechanical or bolted tap, so it has to be pressed with a compression tool and the correct die, not tightened with a wrench. A 2-1/2 inch barrel of this class is normally a hydraulic or battery tool job. There is no screw or bolt to re-tension, which is why it is used where a maintenance-free connection is required.
7) I need to tap three conductors off one run. Will one WR399L do it?
No. The WR399L is built for two conductors, the run and a single tap. For additional taps you need a separate connector per tap, or a multi-tap connector rated for the extra conductors.
8) What part number do I order for the Blackburn 2-1/2 inch H-tap, and where is it made?
Order it as Blackburn WR399L, sold each. Country of origin is Mexico.
