Blackburn APS21-B1-5 – Frequently Asked Questions
1) What wire sizes does the Blackburn APS21-B1-5 split bolt take?
The APS21-B1-5 covers a range of 2/0 through 4 stranded conductor. Both the run and the tap have to land inside that range for the connector to seat properly, so a 6 AWG tap is below what this body is built to grip.
2) Can I use the Blackburn APS21-B1-5 split bolt on both copper and aluminum conductors?
Yes. It is a dual rated connector, so it can be used on copper or aluminum, including a copper-to-aluminum combination. The body itself is aluminum with a tin plated finish, which is what makes the mixed-metal connection acceptable.
3) Does the APS21-B1-5 split bolt need to be taped or insulated after installation?
Yes, treat it as a bare mechanical connector. A split bolt is an uninsulated tap connector, so once the run and tap are torqued down you cover it with an insulating putty and tape buildup or a snap-on split bolt cover rated for the circuit voltage.
4) Split bolt or compression connector for a 2/0 aluminum tap?
A split bolt like the APS21-B1-5 is a mechanical connection, tightened with a wrench, so it needs no hydraulic crimper and can be taken apart later if the tap changes. A compression sleeve is permanent and needs the matching die set. For service and maintenance taps in a pull box or gutter, the split bolt is the practical choice; for a buried or submersible splice, compression is the usual call.
5) Is the Blackburn APS21-B1-5 sold individually or in a box?
It sells each, one connector per unit. Order the quantity of taps you actually have to make rather than assuming a carton count.
6) Why tin plated aluminum instead of plain copper alloy on a split bolt?
Tin plating over the aluminum body is what lets one connector serve copper, aluminum, or a mix of the two. It slows oxidation on the contact faces and keeps a copper conductor from bearing directly on bare aluminum. That is the same reason it carries the dual rating.
7) Where is the Blackburn APS21-B1-5 made?
Blackburn lists Mexico as the country of origin for the APS21-B1-5. That is the figure to use when a government or institutional job asks for country-of-origin documentation on electrical materials.
