Blackburn 2AAW – Frequently Asked Questions
1) What wire sizes does the Blackburn 2AAW split bolt connector take?
The 2AAW covers a range of #1 stranded down to #8 solid, which is what the "1STR-8SLD" in the part description means. Both the run and the tap have to fall inside that range. Anything larger than #1 stranded or smaller than #8 solid needs a different split bolt size.
2) Can I use the Blackburn 2AAW aluminum split bolt on copper conductors, or is it aluminum only?
The body is aluminum with an electro tin-plated finish, and it is UL listed under E9809. Aluminum-bodied tin-plated split bolts of this type are the ones used for aluminum-to-aluminum and aluminum-to-copper taps; the tin plating is what keeps the dissimilar metal contact from corroding. Use an oxide inhibiting compound on the aluminum conductor as the installation instructions require.
3) Is the 2AAW split bolt a UL listed connector for inspection?
Yes. It carries UL file E9809, so it satisfies an inspector looking for a listed mechanical connector on a tap or splice. It is a mechanical connector, meaning it is tightened with a wrench rather than crimped, so no die set or hydraulic tool is needed on site.
4) Does the Blackburn 2AAW come with a spacer, and when do I need it?
Yes, it ships with the spacer, which is what "W/SP" means in the part name. The spacer goes between the two conductors when you are tapping a small wire off a much larger one, keeping both conductors seated in the bolt grooves so the pressure is even instead of the small wire being crushed. On same-size or close-size conductors it can be left out.
5) Do I still need to tape or insulate a split bolt connector like the 2AAW?
Yes. A split bolt is a bare mechanical connector, so the finished tap has to be insulated in the field with rubber splicing tape and an overwrap of vinyl electrical tape, or with a suitable insulating cover, built back to the insulation level of the conductors. Nothing insulating is supplied with the connector.
6) What is the difference between an aluminum split bolt like the 2AAW and a copper split bolt?
Material and where they are approved. The 2AAW has an aluminum body with electro tin plating, which is the configuration used where aluminum conductors are involved, including aluminum to copper taps. Copper alloy split bolts are for copper-to-copper only and should not be put on aluminum conductors. If the run is aluminum USE, URD or triplex, the aluminum bodied connector is the correct choice.
7) Is the Blackburn 2AAW sold individually or in a bag of multiples?
It is sold each, so quantity one gets you a single split bolt with its spacer. Order a count per tap; a service or feeder splice typically needs one per phase plus one per neutral or ground conductor being joined.
8) Where is the Blackburn 2AAW split bolt made? I need country of origin for a government job.
Country of origin is Mexico. That is the documented origin for the 2AAW if you are filling out a submittal or a domestic preference form.
