Blackburn CF402-1P – Frequently Asked Questions
1) What is a Blackburn CF402-1P H-tap connector used for?
The CF402-1P is a copper H-tap compression connector, used to splice a tap conductor onto a run conductor with a hydraulic crimp tool. The H shape captures both conductors in a single die crimp, making a permanent connection rather than a mechanical set-screw joint. It is a wire connector for copper conductors only.
2) Can I use the Blackburn CF402-1P on aluminum conductors?
No. The CF402-1P is a copper connector for copper conductors. For aluminum or for aluminum-to-copper transitions you need a connector rated AL9CU or equivalent dual-rated type, not this one.
3) Does the Blackburn CF402-1P need a special crimp tool?
Yes. It is a compression connector, not a set-screw or split-bolt type, so it has to be crimped with a hydraulic or battery compression tool using the die the connector is indexed for. There is no way to make this connection up with hand tools, and a partial crimp is a failed connection.
4) Is the Blackburn CF402-1P tin plated, and does that matter for direct burial or damp locations?
Tin plated over copper. The plating slows oxidation on the connector body and at the crimp interface, which is why tin plated copper compression taps are the usual choice in wet, damp, and underground pull-box applications rather than bare copper.
5) Do I need to insulate a Blackburn CF402-1P after crimping?
Yes, the CF402-1P is a bare metal tap. Once crimped it has to be re-insulated to the level of the conductor insulation, typically with a heat shrink tube, a cold shrink sleeve, or taped build-up, before the splice is energized or buried.
6) Should I use an H-tap or a split bolt for tapping a copper feeder?
A split bolt is mechanical and can be taken apart, which suits temporary or serviceable connections but needs taping and periodic torque checks. The CF402-1P compression H-tap is permanent: one die crimp captures run and tap conductor, there is nothing to loosen, and it fits more easily inside a crowded pull box. Pick the H-tap where the splice is buried, potted, or otherwise not going to be revisited.
7) How is the Blackburn CF402-1P sold, individually or in a box?
Each. The CF402-1P is sold as a single connector, so order one per splice you are making and allow spares for miscrimps.
8) Where is the Blackburn CF402-1P made?
Mexico. That matters on jobs with domestic sourcing requirements such as Buy America provisions, so check the spec on public work before ordering.
