Blackburn 2H3 – Frequently Asked Questions
1) What wire range does the Blackburn 2H3 split-bolt connector take?
The Blackburn 2H3 is a high-strength split-bolt connector rated for #2 solid through #6 solid conductor. Run and tap both need to fall inside that range; for larger conductors you need a bigger split bolt in the same family.
2) What is the Blackburn 2H3 split bolt made of, and can I use it on copper grounding conductors?
Bronze alloy body, metallic finish. Bronze alloy split bolts are the standard mechanical connector for copper-to-copper splices and taps, including copper ground conductors, which is the usual job for a 2H3.
3) Do I need to tape or insulate a Blackburn 2H3 split bolt after I make the connection?
Yes. The 2H3 is a bare mechanical connector, not an insulated one, so the completed splice has to be insulated in the field with tape or an insulating cover unless it is a grounding connection where bare is acceptable. Nothing is included for that.
4) What is the exact part number and manufacturer for the 2H3 high-strength split bolt?
Blackburn, part number 2H3. That is the number to quote for a straight replacement; the H in the designation marks the high-strength series.
5) Is the Blackburn 2H3 sold individually or in a box?
Sold each. Order the quantity of pieces you need for the job; the price and the pack are per connector.
6) Where is the Blackburn 2H3 connector manufactured?
Made in Mexico. Submittal packages on government and institutional jobs often ask for country of origin, so that is the value to put on the form.
