Blackburn CTP202 C-TAP, No1-2/0 MAIN, No6-2 TAP

The CTP202 C-tap takes a main run conductor from No. 1 through 2/0 and a tap conductor from No. 6 through No. 2. If your main is smaller than No. 1 or larger than 2/0, this is the wrong C-tap in the range and you need the size above or below it.

Copper. The CTP202 is a copper C-tap, so it is intended for copper conductors such as grounding electrode conductors and bonding jumpers. Don't use a copper-only connector on aluminum conductors; that calls for a dual-rated AL9CU connector instead.

Yes. It's a compression connector, part of the E-Z-Ground compression grounding line, so it has to be crimped with a hydraulic or battery compression tool and the correct C-tap die for the connector size. There is no bolt or set screw on it, so it cannot be installed with a wrench or standard pliers.

A C-tap is a crimped tap connection: the main conductor and the tap sit in the C-shaped copper body and the tool closes it into a permanent, irreversible joint. That makes it the choice for grounding grids, ground ring taps, and bonding jumpers where you want no threads to loosen and nothing to retorque later. A split bolt or mechanical connector is the pick when the joint has to come apart again for testing or future changes.

No. The CTP202 tops out at 2/0 on the main, so a 4/0 main run needs a larger C-tap from the same E-Z-Ground compression family. On a job with mixed conductor sizes, plan on more than one C-tap size and matching dies.

It's sold each, so you can order the exact count you need for the number of taps on the job rather than buying a full carton.

Country of origin on the CTP202 is the United States, which is what government and federally funded projects with domestic preference language usually need documented on grounding hardware.
