Blackburn BC4040 – Frequently Asked Questions
1) What conductor sizes does the Blackburn BC4040 C-tap take on the run and the tap?
The BC4040 is sized for 3/0 to 4/0 AWG on both the main run and the tap, so it is a same-size-to-same-size connector rather than a reducing tap. If your tap conductor is smaller than 3/0, you need a different C-tap catalog number sized for that combination.
2) Can I use the BC4040 C-tap on aluminum conductors?
No. The BC4040 is a copper connector intended for copper conductors only. For aluminum or aluminum-to-copper splices you need a connector rated for that metal, since a copper-only compression tap on aluminum risks a poor, corroding joint.
3) Is the BC4040 crimped or bolted, and what tooling do I need?
It's a compression C-tap, crimped with a hydraulic or battery compression tool and the die matched to the connector, not bolted. There is no hardware to torque and nothing is included with the connector, so plan on the correct die set plus tape or a cover for insulating the finished joint.
4) I have an old order calling out part 7TAA269830R0008. Is the BC4040 the same thing?
Yes, 7TAA269830R0008 is the current replacement product ID for the Blackburn BC4040 copper compression C-tap, so an older BC4040 callout and that number get you the same 3/0-4/0 connector.
5) Is the BC4040 sold individually or in a bag of multiples?
Sold each, so the quantity you order is the number of taps you get. For a three-phase tap plus neutral, that's four pieces per splice point.
6) We spec domestic-made electrical connectors. Where is the Blackburn BC4040 made?
United States. That matters on federally funded and Buy American jobs where connectors and fittings have to be domestically produced.
