Blackburn CTP500250 – Frequently Asked Questions

1) Can I use this C-tap on aluminum conductors?
No. The CTP500250 is a copper C-tap and is for copper conductors. Aluminum runs need a connector listed for aluminum (or dual-rated AL9CU), otherwise you get a dissimilar metal connection at the splice.
2) Is this a reusable mechanical connector or a permanent crimp?
Permanent. The C-tap is a compression connector, crimped onto the main and tap with a hydraulic or battery compression tool and the correct die. There is no bolt to back off, so it is not removable for re-taps. If you need a connection you can open later for testing or maintenance, use a bolted mechanical tap instead.
3) Can I tap two different size conductors with one C-tap, like a 500 kcmil main and a 4/0 ground?
Yes, that is exactly what a C-tap is for. The CTP500250 is built with separate main and tap ranges, 300 to 500 kcmil on the main and 3/0 through 250 kcmil on the tap, so unequal conductor sizes are the normal case. Both must be copper and both must land inside their own range.
4) Is the Blackburn C-TAP made in the USA for Buy American jobs?
Yes, the CTP500250 is manufactured in the United States, which matters on federal, municipal and utility contracts carrying domestic sourcing requirements.
5) Where is a 300-500 main C-tap like this typically used on a job?
Service entrance and panel grounding, equipment bonding, industrial grounding grids, and utility work, anywhere you need to tap a grounding electrode conductor or bonding jumper off a large copper feeder without cutting the run. Sizes this large usually show up at the service or on a main ground bus.
6) How is the Blackburn CTP500250 sold, individually or in a bag?
It is sold each, one connector per unit, under part number CTP500250. Count your taps and order accordingly; there is no multi-pack behind that number.
