Blackburn PC 250-HM – Frequently Asked Questions
1) What size conductor does the Blackburn PC 250-HM splice take?
The PC 250-HM is sized for 250 kcmil copper conductor, one cable into each end. It joins two conductors of that size in a straight run, so it is not a reducer and not a tap.
2) What does the oil stop feature on this 250 kcmil splice actually do?
The oil stop is a solid barrier in the middle of the barrel, so compound or oil cannot migrate through the splice from one cable into the other. It is what you want when splicing oil-filled or paper-insulated cable, or where a cable runs from a transformer or switchgear compartment into a dry run. A plain through-barrel connector lets that fluid track right through.
3) Is this a crimp connector or a set screw connector?
Compression only. The PC 250-HM is crimped with a hydraulic or battery compression tool and the correct die for the barrel, so there are no set screws and no torque spec to hit. If you want a mechanical connector you can install with a wrench instead, look at a set screw splice rather than this one.
4) Does the Blackburn PC 250-HM come insulated or do I have to cover it myself?
It ships bare, with no insulation on the barrel. You supply the cover: heat shrink, cold shrink, or tape build-up appropriate to the cable voltage. Budget the length for that, the connector body is 3-3/8 inches long before you add any tube over it.
5) Can I use a tin plated copper splice on aluminum conductor?
No. The PC 250-HM is copper barrel, tin plated, and it is a copper-to-copper splice. For aluminum or for an aluminum-to-copper transition you need a connector rated AL9CU or an aluminum body with the proper compound. Putting bare aluminum into a copper connector invites galvanic corrosion at the joint.
6) How much straight room do I need in the box or vault for this splice?
Allow for a 3-3/8 inch connector body plus your two cable bends and whatever insulating cover you build over it. Compression barrels are rigid, so the splice itself cannot be flexed to fit a tight elbow, plan the slack in the cable instead.
7) Will one PC 250-HM splice a three conductor feeder?
One connector handles one splice, joining two conductor ends. A three phase feeder with a neutral needs four connectors, one per conductor, and you stagger them along the run so the finished insulation build-ups do not stack in the same spot.
8) Why is the barrel tin plated instead of bare copper?
Tin plating slows oxidation on the copper barrel, which matters in damp vaults, manholes, and underground pulls where a bare copper surface would dull and corrode. It also keeps the contact surface clean up to the moment you crimp.
9) Is the PC 250-HM sold individually or in a box quantity?
Each. One connector per unit, ordered as the single part number PC 250-HM, so you can buy the exact count for the splices you have rather than a carton. It is manufactured in the United States.
