Blackburn CSP750 – Frequently Asked Questions
1) What conductor size does the Blackburn CSP750 splice take?
The CSP750 is sized for 750 kcmil copper conductor, which is what the 750 in the part number designates. It is a compression splice, so both conductor ends are crimped into the barrel rather than bolted. Copper only, not aluminum or combination use.
2) Can I use a 35 kV rated copper compression splice on a medium voltage feeder?
Yes. The Blackburn CSP750 carries a 35 kV voltage rating, so it is suitable for medium voltage cable splicing up to that class, as well as any lower voltage or service entrance work.
3) Is the Blackburn CSP750 UL listed for inspection sign-off?
It is built to UL file E9809. That is the reference an inspector or a spec writer will want against a compression splice on a copper feeder.
4) Can I use the Blackburn CSP750 to splice aluminum to copper?
No. The CSP750 is a copper-bodied splice intended for copper to copper connections. For an aluminum or mixed aluminum-copper joint you need a dual-rated AL9CU compression splice in the matching 750 kcmil size, not this one.
5) What is the difference between a short barrel and a long barrel copper splice?
The CSP750 is a short barrel splice, meaning fewer crimps per side and a shorter overall body, which matters when you are working in a tight pull box, handhole, or transformer compartment where a long barrel will not lay in. Long barrel versions give more crimp area for higher pullout resistance. If space is the constraint, the short barrel is the one to use; if you need maximum mechanical hold on a heavily stressed run, look at a long barrel equivalent in the same 750 kcmil size.
6) Is the Blackburn CSP750 a bolted or a crimp connector?
Crimp. It is a wire or cable compression splice, so the joint is made by compressing the barrel onto the conductor with a die set rather than by set screws or bolts. There is no hardware to torque and no re-entry once it is crimped.
7) Why is this copper splice tin plated, and does it need to be for direct burial or wet locations?
The barrel is tin plated over copper. Tin plating slows oxidation on the copper so the crimp interface stays low resistance in damp, buried, or corrosive environments, and it keeps the bore clean before installation. The black finish is the standard color coding on this part.
8) How is the CSP750 sold, one piece or in a bag?
It is sold each, so a single splice per unit ordered. Order two if you are splicing both legs, and remember a 750 kcmil crimp needs a hydraulic tool with the correct die, which is not supplied with the connector.
9) Where is the Blackburn CSP750 splice made?
Country of origin is Mexico, which is the detail a government or institutional buyer working to domestic sourcing rules will need on the submittal.
