Blackburn CTP202N – Frequently Asked Questions
1) What wire sizes does the Blackburn CTP202N C-tap accept on the main and the tap?
The CTP202N takes a main conductor from 1 AWG through 2/0 and a tap from 6 AWG through 2 AWG. Both sides are copper only, so don't use it on aluminum conductors. If your main is smaller than 1 AWG or larger than 2/0, you need a different C-tap size in the series.
2) Is the CTP202N a compression fitting or a mechanical bolted connector?
It's a compression connector. The CTP202N is a copper C-shaped tap that gets crimped with a hydraulic or battery compression tool and the correct die, making a permanent wire or cable compression splice. There are no bolts or set screws, so it cannot be loosened or reused once crimped.
3) Can I use a Blackburn CTP202N C-tap for a direct-buried grounding electrode connection?
Yes. The CTP202N is listed to UL E3060 and meets IEEE 837-2014, which is the standard for permanent connections used in substation grounding, including direct burial and concrete-encased applications. It's a copper compression connector, so pair it with copper ground conductors within the 1-2/0 main and 6-2 tap range.
4) Will a CTP202N work for tapping a #6 ground off a 2/0 service conductor?
That's exactly the range it covers. A 2/0 copper main is the top of the main range and #6 copper is the bottom of the tap range, so a single crimp on the CTP202N handles that combination. Use the die the tool chart calls for on this connector size rather than eyeballing it.
5) Can I use this C-tap on aluminum or copper-clad wire?
No. The CTP202N body is copper and rated for copper conductors only. Putting aluminum in a copper-only compression connector creates a dissimilar-metal joint that corrodes and fails. For aluminum or a copper-to-aluminum transition, use a connector specifically dual-rated AL/CU.
6) Do I need to order a separate crimp die or tap plate with the CTP202N?
The connector is sold individually, one piece per order, and nothing else ships with it. You supply the compression tool and the matching die. Many installers also use an oxide-inhibiting compound on the conductors before crimping, which is a separate item.
7) Is the Blackburn CTP202N made in the USA for Buy American jobs?
Country of origin on the CTP202N is the United States, which is what agency and institutional specs with domestic-content language usually ask for on grounding hardware. The part number to list on the submittal is CTP202N.
