Blackburn PTC1000 R750KNURLED – Frequently Asked Questions
1) What is the Blackburn PTC1000 R750KNURLED used for?
It's a compression splice tapered reducer, used to splice two conductors of different sizes together in one crimped joint. The Blackburn PTC series reducer accepts the larger conductor at one end and the smaller at the other, so you don't need a separate adapter or pin. Connection is made by compression crimp, not mechanical set screw.
2) Does this Blackburn reducer come insulated, or do I have to tape or shrink over it?
It ships bare, with no insulation on the barrel. Anywhere the splice needs to be insulated, you cover it in the field with heat shrink, a cold shrink tube, or tape rated for the circuit voltage. In a grounding or bonding application it's normally left bare.
3) Can this splice be used outdoors, in a vault, or in a direct-burial application?
It's rated for harsh environments, and the barrel is tin-plated, which is what protects the copper from corrosion in damp vaults, coastal air, and underground enclosures. Tin plating is also what lets it land on either copper or aluminum without the galvanic issue a bare copper barrel creates.
4) How long is the PTC1000 R750 barrel, and will it fit in my handhole or box?
The reducer measures 6 inches in length. That's the number to check against the depth of a handhole, junction box, or cable trough before you commit, since a compression splice needs straight run on both sides of the barrel for the crimp dies to close without fouling the enclosure wall.
5) Why use a tapered reducer instead of a straight splice with a reducing pin?
A tapered reducer handles the size change inside one barrel, so the run has a single crimped joint instead of a pin plus a splice. Fewer interfaces means fewer places to lose contact pressure. Use a straight compression splice when both conductors are the same size; reach for the tapered reducer like the PTC1000 R750 when the two ends are different sizes.
6) Do I need a special crimp tool for the Blackburn PTC1000 R750KNURLED?
Yes. This is a compression connector, so it has to be installed with a hydraulic or battery compression tool and the die set the manufacturer calls out for the barrel, not with a mechanical wrench or a hand lug crimper. The knurled barrel marks the crimp locations.
7) Is this Blackburn connector made in the USA for a Buy American spec job?
Country of origin is the United States. That's the line a government, transit, or federally funded project submittal usually needs. The part number to show on the submittal is PTC1000 R750KNURLED.
8) Is the PTC1000 R750 sold individually or in a bag?
It's sold each, one reducer per unit. Order the count you need for the job, allowing for a spare, since a compression splice is a one-shot install and a miscrimped barrel gets cut out rather than reused.
