Blackburn J2D – Frequently Asked Questions
1) Can the Blackburn J2D ground clamp be direct buried in soil or encased in concrete?
Yes. The J2D is a bronze ground clamp built for direct burial, so it can be installed below grade on a ground rod or water pipe electrode where the connection stays in the earth. Bronze is used for the current-carrying body precisely because it holds up to soil moisture without the galvanic problems a steel or plated clamp runs into underground.
2) Is the Blackburn J2D a UL listed grounding clamp for inspection purposes?
The J2D carries UL under file E3060, which is the reference an inspector or AHJ will want when the grounding electrode connection is being signed off. It is catalogued as a grounding device assembly, not a general purpose pipe clamp.
3) Is a standard indoor ground clamp acceptable for a buried ground rod connection, or do I need a burial rated one?
For any connection that ends up below grade, use a clamp identified for direct burial, which is what the bronze J2D is. Clamps not marked for burial are meant for accessible above grade connections only, and an inspector will flag a non burial clamp in a rod pit or under a slab. If the connection will instead sit in an accessible above grade location, a standard listed clamp will do.
4) Does the Blackburn J2D ground clamp come insulated or with a boot?
No insulation. The J2D is a bare bronze clamp, which is what a grounding electrode connection wants anyway, the metal to metal path is the point. If your job calls for a covered or insulated connection, this is not the part.
5) What is the exact part number to order for the Blackburn bronze burial ground clamp, and is it sold individually?
Order it as Blackburn J2D. It is sold each, one clamp per unit, so quantity on a purchase order equals the number of connections you are making. Country of origin is India.
