Blackburn BC48 – Frequently Asked Questions
1) What wire sizes does the Blackburn BC48 C-tap connector take?
The BC48 is sized for a No. 6 run with a No. 4 tap, per its CU COMP CONN C-CRIMP No6-No4 designation. It is a copper compression C-tap, so both conductors must be copper, and it is crimped, not bolted, meaning you need a compression tool with the matching die to make the connection.
2) Can I use a copper C-tap like the BC48 on aluminum conductors?
No. The BC48 is a copper-bodied compression connector intended for copper conductors only. For aluminum or copper-to-aluminum taps you need a connector rated AL9CU or an aluminum-bodied tap, not this one.
3) Does the BC48 C-tap need to be insulated after crimping?
Yes. The BC48 is a bare copper compression C-tap with no insulation of its own, so the finished connection has to be covered with tape, a heat-shrink or cold-shrink sleeve, or an insulating cover suited to the circuit voltage.
4) I have a drawing calling out part 7TAA269830R0014 for a copper tap. Is the BC48 the same part?
Yes. 7TAA269830R0014 is the current replacement product ID for the Blackburn BC48, so a spec or older order referencing that number is filled by this connector.
5) Should I use a compression C-tap like the BC48 or a split-bolt for a service tap?
A compression C-tap such as the BC48 is crimped once with a die tool and stays put, so it suits underground, pedestal, and buried or inaccessible splices where nothing will be retorqued later. A split-bolt is mechanical and can be taken apart, which is the better choice when you want a reworkable connection or do not have the crimp tool and die on site.
6) Is the BC48 sold individually or in a bag of connectors?
Each. The selling unit on the BC48 is a single connector, so order the exact count of taps your job needs rather than a bulk pack.
7) Where is the Blackburn BC48 tap connector made?
The BC48 is made in the United States, which matters on federal, municipal, and other domestic-preference jobs where the electrical bill of materials has to show country of origin.
