Blackburn SAC 750 CPTR400CPTTN – Frequently Asked Questions
1) Can the Blackburn SAC 750 CPTR400CPTTN reducer be used on both aluminum and copper conductors?
Yes. The SAC 750 CPTR400CPTTN is an AL/CU rated compression reducer, so it accepts aluminum or copper on either end. The barrel is tin plated, which is what makes the dual-rated use acceptable when aluminum and copper are joined in the same connector.
2) What conductor sizes does the Blackburn 750 to 400 compression reducer join?
It steps 750 kcmil down to 400 kcmil, one size per end. It is a reducing splice, not a straight splice, so use it only where the two conductors are genuinely those two sizes.
3) Is this Blackburn reducer insulated, or do I have to tape or sleeve it after crimping?
There is no insulation on the connector itself, so the joint has to be insulated in the field with tape, heat shrink, or a cold shrink sleeve. Plan the sleeve length around a 6.250 inch long body with a 1.594 inch outside diameter.
4) Will a 750-400 compression reducer this size fit inside my pull box or gutter?
Check for at least 6.250 inches of straight run plus bending room. The barrel is 6.250 inches long with a 1.594 inch outside diameter before any insulating sleeve is added, so the finished joint will be larger than that once taped or shrink sleeved.
5) Does the Blackburn SAC 750 CPTR400CPTTN meet ANSI C119.4 for aluminum connections?
Yes, this compression reducer is built to ANSI C119.4, the standard covering connectors for aluminum and aluminum-to-copper conductors. That is the reference specifiers usually want on the submittal for a dual rated splice.
6) Do I need a hydraulic crimper for this splice, or can I use a set screw connector instead?
This is a compression connector, so it has to be crimped with the correct die, not tightened with a wrench. If you do not have a hydraulic or battery crimp tool on site, a mechanical set screw reducer is the alternative connection type for a 750 to 400 transition.
7) How is the Blackburn 750-400 aluminum reducer sold, individually or in packs?
Sold individually, each. Order one per splice, and remember insulating material is separate since the connector ships bare.
8) Is the Blackburn SAC 750 CPTR400CPTTN made in the USA for a Buy American job?
Country of origin is the United States, which is the line procurement officers on federal and institutional work usually need documented. The ordering part number is SAC 750 CPTR400CPTTN.
