Blackburn E-6HPS-25 SPLIT BOLTS CONNECTORS

The E-6HPS-25 split bolt is rated for 12 through 6 AWG conductors. That covers the common branch circuit and small feeder range, so you can tap a 6 AWG run down to a 12 AWG conductor with the same connector. Anything larger than 6 AWG needs a bigger split bolt.

The E-6HPS-25 body is bronze alloy with a tin plated finish. Tin plating over a bronze alloy is what makes a connector suitable for copper and, where the connector is listed for it, aluminum conductors, because the tin barrier keeps the dissimilar metals from contacting directly. On a copper to aluminum splice you still need an oxide inhibiting compound on the aluminum conductor.

Yes. A split bolt is a bare mechanical connector, so the completed splice has to be insulated in the field with rubber splicing tape and a jacket of vinyl electrical tape, or covered with a snap on split bolt insulating cover sized to the connector. No insulation comes on the connector itself.

It sells as each. The 25 in the E-6HPS-25 is part of the Blackburn catalog designation, not a pack quantity, so order one unit per splice you intend to make.

A split bolt like the E-6HPS-25 clamps two conductors between the bolt legs and a spacer, tightened with two wrenches, and is the cheap standard for a copper tap in a pull box or gutter where you can tape the joint. A set screw or insulated multi tap block is the better choice when you want a factory insulated body, no taping, and the ability to land several conductors in separate ports. For a single 12 to 6 AWG tap with room to insulate, the split bolt is the simpler part.

The E-6HPS-25 is a bronze alloy, tin plated split bolt for 12 to 6 AWG conductors, which is the size range typical of bonding jumpers and grounding electrode conductors in commercial branch work. Bronze alloy is the material used for direct burial and grounding rated split bolts. For any buried or concrete encased connection, confirm the specific listing your inspector requires for that application.

Manufacturer part number E-6HPS-25, Blackburn brand, made in Mexico. Order by that MPN, since the numeric suffix on split bolt catalog numbers distinguishes the conductor range and not the quantity.
