Blackburn AC 750 R 500 – Frequently Asked Questions
1) Will the Blackburn AC 750 R 500 splice join a 500 kcmil conductor to a 750 kcmil conductor?
That is exactly what the AC 750 R 500 is built for. It's a straight reducing compression splice, so the two barrels are different sizes: one end takes 750 kcmil, the other takes 500. It joins two conductors end to end, and each end is crimped with a compression tool and the correct die for that barrel. If both of your conductors are the same size, you want a straight (non-reducing) splice instead, not this one.
2) Is the Blackburn AC 750 R 500 reducing splice for aluminum or copper conductors?
It's an aluminum-bodied splice, per the AL in the part description. Bare aluminum compression connectors of this type are normally installed with an oxide inhibitor on the conductor strands. If you're splicing copper to copper, this isn't the connector to order.
3) How long is the Blackburn AC 750 R 500 splice, and will it fit in my pull box or gutter?
The body measures 3-11/16 inches long. Add your bending radius on both sides when you're checking clearance in a pull box, wireway, or gutter, and remember the finished splice will be longer once it's taped or heat shrunk. For 500 and 750 kcmil aluminum, the conductor bend is usually what limits you, not the splice itself.
4) Does the AC 750 R 500 splice come insulated, or do I have to tape or heat shrink over it?
It ships bare, with no insulation on the barrel. You cover it in the field, whatever your spec calls for: tape, heat shrink tubing, or a cold shrink sleeve. Order that covering separately, because nothing comes with the splice.
5) What standard does the Blackburn AC 750 R 500 compression splice meet?
It's built to ANSI C119.4, the standard covering connectors for use between aluminum and copper conductors. That's the spec electrical inspectors and engineers reference for compression connectors on this kind of feeder work, so it's the line to cite on a submittal.
6) Is the Blackburn AC 750 R 500 splice made in the USA for a Buy American job?
Country of origin is the United States. That's the value to carry onto a submittal for federally funded or Buy American specified work.
7) Can I use a mechanical set screw connector instead of the AC 750 R 500 compression splice?
They do the same job differently. A compression splice like the AC 750 R 500 is crimped once with a hydraulic tool and the matching die, and it cannot be taken apart or re-torqued, which is why specs on feeder splices often call for compression. A mechanical connector goes on with a hex key or torque wrench and needs no crimper, but it's a bolted joint that can be specified against. If your drawings say compression, this is the family you're in; if they don't, and you have no crimper on the truck, price a mechanical reducer instead.
8) Is the Blackburn AC 750 R 500 sold each or in a bag of connectors?
Sold one at a time. Count one per splice point and add spares, since a compression connector that gets crimped on the wrong die is scrap.
