Blackburn E-10H-25 – Frequently Asked Questions
1) What wire sizes does the Blackburn E-10H-25 split bolt connector take?
The E-10H-25 split bolt is rated for a 1/0 stranded main conductor down to a 10 AWG solid tap. That range covers the typical service or feeder tap where you are running a smaller ground or branch conductor off a larger run. If your main is bigger than 1/0 or your tap smaller than 10 AWG, this is the wrong size in the line.
2) What is the Blackburn E-10H-25 split bolt made of, and can I use it on copper grounding conductors?
It is a silicon bronze alloy body, which is the standard material for copper-to-copper splices and grounding taps. Bronze split bolts are used with copper conductors; for aluminum or combination copper-to-aluminum work you need a connector specifically rated for that service, not this one.
3) Does a split bolt connector need to be taped or insulated after installation?
Yes. A split bolt like the E-10H-25 is a bare mechanical connector, so the completed tap has to be insulated to the same level as the conductor insulation, normally with rubber splicing tape covered by vinyl electrical tape, or with a molded split bolt insulating cover. Tape and covers are not supplied with the connector.
4) Can I use one split bolt to tap two conductors of different sizes?
That is exactly what this one is built for. The E-10H-25 accepts a larger run conductor and a smaller tap in the same bolt, anywhere from 1/0 stranded down to 10 AWG solid, so you can pull a ground or a small branch off a feeder without a separate reducer. Both conductors must fall inside that range.
5) Is the Blackburn E-10H-25 sold individually or in a box?
Individually. The selling unit is each, so order the exact count of taps you need for the job rather than a carton quantity.
6) Where is the Blackburn E-10H-25 split bolt made?
Production is sourced from Mexico and the United States. If your project carries a domestic-content requirement, specify country of origin on the purchase order, since both origins ship under the same part number.
