Blackburn CTP25020 – Frequently Asked Questions

1) Will a Blackburn CTP25020 C-tap take a 4/0 main run with a #2 ground tap?
Yes. The CTP25020 C-tap is rated for main conductors from 3/0 through 250 kcmil and taps from #6 through 2/0, so 4/0 main with a #2 tap falls inside both ranges. Anything smaller than 3/0 on the run or larger than 2/0 on the tap needs a different C-tap size.
2) Do I need a crimp tool for the Blackburn CTP25020, or can it be bolted?
This is a compression-only fitting. The C-tap is crimped with a hydraulic or battery compression tool and the correct die for the conductor combination, and once crimped it's permanent, not re-openable like a split bolt or a bolted lug. If you need a connection you can take apart later, a mechanical connector is the better choice.
3) Is the Blackburn C-TAP connector copper or aluminum, and can I use it on a copper ground conductor?
It's a copper compression connector, so it pairs directly with copper conductors without any dissimilar metal concern on the connection itself. Copper also holds up better against corrosion in buried and damp grounding electrode work.
4) What kind of jobs is a C-tap grounding connector used for versus a ground rod clamp?
A C-tap taps a smaller grounding conductor off a larger continuous run without cutting the run, which is what you want for service entrance grounding, panel ground connections, transformer and generator grounding, lightning protection tie-ins and telecom equipment grounding. A ground rod clamp is for terminating to the rod itself, so the two are complementary parts of the same electrode system, not substitutes.
5) Is the Blackburn C-TAP made in the USA for a Buy American spec job?
Country of origin on the CTP25020 is the United States, which is what federally funded and Buy American specified electrical work generally requires documentation for.
6) What is the exact part number to order this 3/0-250 main C-tap from Blackburn?
Blackburn part number CTP25020, the C-TAP copper compression tap covering 3/0 to 250 kcmil main and #6 to 2/0 tap.
7) Is the Blackburn CTP25020 sold individually or in a bag?
It ships each, one connector per unit, so you order the exact count of taps the job needs rather than a fixed bag quantity.
