Blackburn 8H3 – Frequently Asked Questions
1) What wire sizes does the Blackburn 8H3 split bolt connector take?
The 8H3 is a high-strength split bolt sized for 8 through 12 AWG solid conductors. It's a mechanical connector, so the run and tap are clamped between the bolt body and the pressure bar rather than crimped, which means you can service or re-tension the joint later with a wrench.
2) Can I use a Blackburn 8H3 split bolt on copper grounding conductors?
The 8H3 body is bronze alloy, the standard material for copper-to-copper mechanical taps, and it handles 8 to 12 AWG solid wire. That covers the usual 8 and 10 AWG copper grounding electrode and equipment grounding conductor sizes. For aluminum or copper-to-aluminum connections you need a connector specifically rated AL9CU instead.
3) What does the H in the Blackburn 8H3 split bolt mean?
It designates the high-strength version of the split bolt. Same bronze alloy body and split-bolt form as a standard tap connector, built for a higher tightening torque on the joint. The part number to order is 8H3.
4) Does a split bolt connection need to be taped or insulated after installation?
Yes. The 8H3 is a bare bronze alloy connector with no insulating cover, so any joint on an energized conductor has to be re-insulated, normally with rubber splicing tape built back to the conductor insulation thickness and overwrapped with vinyl tape, or covered with an insulating cap. On a bare grounding conductor tap, no insulation is required.
