Blackburn WR339 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR339 H-tap connector accept?
The WR339 is sized for a 3/0 ACSR run conductor with a 2/0 through 1 tap, which is what the catalog designation AL HTYPE COMP CONN 3/0ASCR 2/0-1 spells out. It is a two conductor connector, so one run and one tap per fitting. If your run or tap falls outside that range, you need a different H-tap die size rather than forcing this one.
2) Does the Blackburn WR339 meet utility connector specifications?
It is RUS accepted and complies with ANSI C119.4, the standard covering electric connectors for use between aluminum and copper bare overhead conductors. That is the pairing utility and co-op inspectors typically look for on a distribution or service tap.
3) Is the WR339 a compression connector or a bolted tap?
Compression. The WR339 is crimped with a hydraulic tool and the correct die, not bolted, so once it is pressed it is a permanent tap that cannot be loosened and re-tensioned like a bolted split-bolt or H-tap. Plan on tooling being on site before you order.
4) Does the Blackburn WR339 come insulated, or do I have to cover it after crimping?
It ships bare aluminum with no insulation on the body, so the connection has to be insulated in the field, typically with tape, a cover, or heat shrink, wherever the application calls for it. Grounding and utility taps are often left bare.
5) Can I use the WR339 H-tap on 90 degree C rated cable?
Yes. The WR339 is rated for service up to 90 degrees C, so it matches 90 degree C rated conductor insulation systems such as THHN or XHHW-2 at their full temperature rating.
6) Will a WR339 work for tapping copper conductors?
The WR339 is an aluminum bodied H-tap. Aluminum compression taps of this type are commonly rated dual-rated AL/CU, but the only conductor called out for this one is 3/0 ACSR on the run with a 2/0 to 1 tap, so treat it as an aluminum/ACSR tap. For an all copper splice, specify a copper compression tap in the matching conductor sizes instead.
7) How long is the WR339 connector body, and will it fit in a tight enclosure?
The body measures 2-1/8 inches in length. Add clearance for the crimp tool head and die on both crimp positions when you are working inside a pedestal, handhole, or gutter, since the tool footprint is larger than the connector.
8) Is the Blackburn WR339 sold individually or in a bag?
It is sold each, so quantity ordered equals the number of connectors. Count one per tap point and add spares, because a miscrimped compression connector has to be cut out and replaced.
