Blackburn WR699 – Frequently Asked Questions
1) What conductor sizes does the Blackburn WR699 H-tap connector accept?
The WR699 is sized for a 397.5 to 266.8 ASCR main run with a 4 to 6 AWG tap, which is what the 397-266ASCR 4-6 designation on the part spells out. It is a two conductor connector, main plus tap, so it is not intended for bundling additional runs into the same crimp.
2) Is the Blackburn WR699 a compression tap or a bolted/mechanical tap?
Compression. The WR699 is an H-type compression tap, so it is installed with a hydraulic or battery crimp tool and the correct die, not tightened with a wrench. Once crimped it is a permanent connection, which is why utilities and line crews use it on aerial and service taps rather than a re-openable bolted connector.
3) Will the WR699 tap connector meet utility spec requirements?
It is RUS accepted and complies with ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors. That is the pair of acceptances most rural electric co-ops and utility specs call out for compression taps.
4) Can I use the WR699 H-tap to connect aluminum to copper?
The WR699 is an aluminum bodied H-tap that complies with ANSI C119.4, the standard for connectors used between aluminum and copper conductors. Sizing is the thing to hold to: the main side is built for 397.5 to 266.8 ASCR and the tap side for 4 to 6 AWG. Outside that range, move to a different H-tap size.
5) Does the Blackburn WR699 come insulated, or do I need to cover it after crimping?
It ships bare, with no insulation on the body. Plan on covering the finished crimp yourself where the application calls for it, typically with a sealed insulating cover, heat shrink, or tape build-up rated for the circuit.
6) What operating temperature is the WR699 H-tap rated for?
Up to 90 degrees C. That covers standard 90 C rated conductor insulation systems, so the tap is not the limiting element on a typical 75 C or 90 C terminated circuit.
7) How long is the Blackburn WR699 barrel, and will it clear my existing hardware?
The connector measures 2 inches in length, so allow that much clear run on the main conductor plus tool jaw clearance either side before you set the crimp. Tight spans near insulators or deadends are where installers most often run short.
8) Is the Blackburn WR699 sold individually or in a bag of multiples?
Sold each, one connector per unit, under MPN WR699. Order the quantity of taps you need for the job rather than by carton.
