Blackburn PTC 4 – Frequently Asked Questions
1) What is the Blackburn PTC 4 splice used for?
The PTC 4 is a tapered compression splice for joining two conductors end to end. It is a copper splice, tin-plated, with no insulation on the body, so it needs to be taped or covered after crimping. It joins 2 conductors per splice and is sold individually.
2) Is the PTC 4 an oil stop splice for underground or submersible cable?
Yes. The PTC 4 is an oil stop tapered splice, rated by Blackburn for harsh environments. The tapered barrel and oil stop construction are what let it be used where oil or contaminant migration along the conductor is a concern, such as in duct, manhole, and underground runs.
3) Does the Blackburn PTC 4 need a crimp tool, or can it be tightened with a wrench?
It is a compression connector, so it has to be crimped with a hydraulic or mechanical compression tool and the correct die. There are no set screws or bolts on it. If you want a wrench-installed connection, you need a mechanical set screw splice instead.
4) Will the PTC 4 work on aluminum conductor, or copper only?
Copper only. The PTC 4 is a copper splice with tin plating, so it is intended for copper conductors. For aluminum or aluminum-to-copper runs you need a connector rated AL9CU or similar dual-rated compression splice.
5) How long is the Blackburn PTC 4 splice barrel?
Overall length is 1-29/32 inches. That matters when you are splicing inside a tight pull box or under a shrink sleeve, since you need room for the barrel plus the crimp tool head and the covering over it.
6) Does the PTC 4 come insulated, or do I have to cover the splice?
Bare. There is no insulation on the connector, so after crimping you finish it with tape, a heat shrink sleeve, or a cold shrink kit appropriate for the cable voltage.
7) What is the exact part number to order the Blackburn tapered oil stop splice?
The manufacturer part number is PTC 4, from Blackburn. It is a single-model item sold one per unit, and it is made in the United States.
