Blackburn JAB1H – Frequently Asked Questions
1) What size ground rod does the Blackburn JAB1H clamp fit?
The JAB1H is built for a 1 inch ground rod. It will not seat correctly on the smaller 5/8 or 3/4 inch rods used on most residential services, so match the clamp to the rod diameter you actually drove before you order.
2) What conductor range will the JAB1H ground rod clamp accept?
It takes 4/0 stranded down to 8 solid copper. That covers a full-size service grounding electrode conductor at the top end and a small bonding jumper at the bottom, so one clamp handles most of what lands on a 1 inch rod.
3) Can I use aluminum grounding conductor in a Blackburn JAB1H clamp?
The JAB1H is specified for copper conductor. If your electrode conductor is aluminum, use a clamp listed for aluminum rather than forcing this one, since a copper-only connector on aluminum invites galvanic corrosion at the termination.
4) What tool do I need to tighten the JAB1H clamp?
It uses a hex head screw, so a nut driver or socket does the work. No slotted screwdriver fussing in a muddy ground rod trench, and you can get consistent torque on the lug.
5) Is the JAB1H sold individually or in a box?
The JAB1H ground rod clamp is sold each, so you can buy the single clamp for one service or count out exactly what a multi-rod electrode system needs.
6) Is the Blackburn JAB1H an insulated connector?
No, it is a bare mechanical connector with no insulation. That is normal for a grounding electrode termination at the rod, where the connection is intended to be metal to metal and accessible.
