Blackburn AC 800 R 600 HOMAC REDUCING SPLICE

It's a compression reducing splice for joining two conductors of different sizes in a run, Blackburn model AC 800 R 600. Because it reduces, one barrel end takes the larger conductor and the other takes a smaller one, so you can transition cable size in a single connection instead of using an adapter plus a straight splice. It's a two-conductor device, tin-plated, installed with a compression tool and die.

No insulation on it. The AC 800 R 600 is a bare tin-plated compression body, so the joint has to be insulated in the field, typically with heat shrink tubing or tape rated for the circuit voltage. Plan that material into the job before you crimp, because the barrel is 8.250 inches long and the covering has to span it plus overlap onto the cable jacket on both sides.

Yes, the AC 800 R 600 is built to ANSI C119.4, the standard covering connectors for use between aluminum and copper or aluminum-to-aluminum conductors. That's the reference most utility and service entrance specs cite for compression connectors, so it will satisfy a drawing note calling for C119.4 compliance.

The body alone is 8.250 inches long, and that's before insulation overlap and before the bending radius on the two cables entering each end. In a tight junction box or meter pedestal, measure the clear straight run you have; a splice this long plus shrink sleeve typically wants a foot or more of straight space to sit without stressing the terminations.

Compression is the right call where the joint is permanent and buried in a box, duct, or direct burial location you don't want to revisit. It's a one-shot crimp with a tool and matching die, and it gives a consistent joint that won't back off. A mechanical set-screw or bolted connector is what you want if the splice may need to be opened later, or if you have no press on site. The AC 800 R 600 is compression only, so no press means no install.

No. It's a two-conductor splice, one conductor in each end. For bringing three or more conductors together you need a multi-tap or a power distribution block rather than a reducing splice like this one.

Sold each. One AC 800 R 600 reducing splice per unit, so order the count you need for the job rather than a carton quantity.

The Blackburn AC 800 R 600 reducing splice has United States country of origin, which is what a buy-domestic clause on a government or institutional project is asking for.

Tin plating on the copper body is there to resist oxidation and to allow the connector to be used with aluminum conductors without the galling you'd get on a bare copper surface. It handles damp vault and pedestal service, but since the splice ships with no insulation, the corrosion protection of the finished joint depends on the sealing sleeve or tape you apply over it.
