Blackburn PTC 250 – Frequently Asked Questions
1) What is the Blackburn PTC 250 splice used for?
The PTC 250 is a copper compression splice for joining two conductors end to end. It is a tapered oil-stop design, tin-plated, with no insulation on the body, so it is installed bare and then insulated or taped by the installer. Barrel length is 2-9/16 inches.
2) Does the Blackburn PTC 250 come pre-insulated or do I need to tape it?
It ships bare. Insulation material on the PTC 250 is listed as none, so you finish the joint yourself with tape, heat shrink, or a cold shrink sleeve sized to the 2-9/16 inch barrel plus overlap onto the cable jacket.
3) Can I install a Blackburn PTC 250 splice with a mechanical set screw tool, or does it need a crimper?
It has to be crimped. The PTC 250 is a compression connector, not a set screw type, so you need a hydraulic or battery compression tool with the correct die for the barrel. No screws, no bolts.
4) Is the Blackburn PTC 250 suitable for aluminum conductors?
No. It is a copper splice, tin-plated for corrosion resistance. For aluminum or aluminum-to-copper runs you need a connector rated AL9CU or aluminum-bodied; using a copper-only barrel on aluminum is the wrong part.
5) What does the oil stop feature on a tapered copper splice actually do?
An oil-stop splice has an internal barrier between the two conductor entries so oil or compound cannot migrate through the barrel from one cable into the other. That matters on paper-insulated and oil-filled cable transitions. The PTC 250 is built as a tapered oil-stop splice and is rated by the manufacturer for harsh environments.
6) Will the Blackburn PTC 250 hold up in a wet vault or direct-buried splice box?
It is listed for harsh environments, and the tin plating on the copper barrel resists corrosion. Because the barrel carries no insulation, the moisture seal on a buried or submerged splice comes entirely from the sealing system you apply over it, not from the connector.
7) How is the Blackburn PTC 250 sold, individually or in a box?
Each. The selling unit of measure on the PTC 250 is a single connector, so order one per splice point plus whatever spares the crew wants on the truck. It is made in the United States.
8) What is the manufacturer part number to order this Blackburn splice?
Order it as Blackburn PTC 250. That is the only model configuration of this tapered copper compression splice, so there is no size or finish choice to specify when you order.
