Blackburn WR139 – Frequently Asked Questions
1) What wire sizes does the Blackburn WR139 H-tap connector accept?
The WR139 is an aluminum H-type compression tap rated for a main run of 1/0 through 4 ASCR and a tap of 2/0 through 3. Match your conductor size to that range before crimping; an H-tap outside its stated conductor range will not compress to a reliable connection.
2) Is the WR139 tap connector insulated, or do I have to cover it after crimping?
No insulation on it. The WR139 ships as a bare compression tap, so the splice needs to be insulated in the field with tape, a cover, or a shrink boot, or installed where an uninsulated connection is acceptable such as inside a pedestal or enclosure.
3) Will a utility or co-op accept the WR139 on a distribution job?
It is RUS accepted and complies with ANSI C119.4, which is the specification utilities and rural electric cooperatives typically call out for sealed and unsealed connector systems on distribution conductors.
4) Does a WR139 H-tap need a crimping tool, or can it be bolted or set screwed?
Compression only. This is a crimp connector, not a mechanical set-screw or bolted tap, so it takes a hydraulic or battery compression tool with the correct die. If you need a connection that can be torqued with a wrench and taken apart later, use a mechanical set-screw tap instead.
5) Can I use the Blackburn WR139 H-tap on copper conductors, or is it aluminum only?
It is an aluminum-bodied H-type compression tap. Because it meets ANSI C119.4, it is built for the connection classes that standard covers for aluminum and copper-to-aluminum service connections. Verify your conductor metal matches the sizes marked on the connector, and use the manufacturer-specified die for the crimp.
6) How hot can a Blackburn WR139 compression connection run?
Rated for conductor operating temperatures up to 90 degrees C, so it suits 90 C rated cable such as XHHW-2 or RHW-2 without derating the connector itself.
7) How much room do I need for the WR139 H-tap inside a pedestal or handhole?
The connector body is 1-1/2 inches long, so plan for that plus the crimped conductor bends and whatever insulating cover you add over the splice.
8) Is the Blackburn WR139 sold individually or in a box?
Sold each, so order one per tap connection you are making. Count your splices, not your reels.
9) What part number do I give my distributor for this Blackburn aluminum H-tap?
Blackburn WR139 is the manufacturer part number. It is made in Mexico and covers a 1/0 to 4 ASCR main with a 2/0 to 3 tap.
