Blackburn JDLI-1 DIRECT BUR LAY-IN GRND CLP 10-2 AWG

The JDLI-1 lay-in grounding clamp is rated for 10 AWG through 2 AWG conductors, so it covers the usual range of grounding electrode conductors and bonding jumpers in that band. One clamp handles the whole 10-2 span, so you don't need separate parts for a #8 bond and a #4 run.

Yes. The JDLI-1 is a direct burial rated clamp, so it can be used on buried grounding electrode connections such as ground rods and buried bonding runs rather than being limited to dry above-grade locations.

No. The JDLI-1 tops out at 2 AWG, so a 4/0 grounding electrode conductor is outside its range. For a large service ground you need a clamp or connector rated for that conductor size instead, or a compression connection sized to 4/0.

A lay-in clamp lets you drop the conductor into an open channel and tighten it down, so the wire does not have to be threaded through a closed hole or cut. That makes it the practical choice for a continuous grounding run that passes through the connection point, and for retrofits where you cannot free an end of the conductor. Compression lugs and exothermic welds give a permanent connection but require pulling the wire end, dies or a mold, and cannot be reopened for inspection. The JDLI-1 is the lay-in type, direct burial rated, for 10-2 AWG.

It ships as a single clamp, each. For a service that needs several electrode and bonding connections, order the count you need per connection point.

Order it as Blackburn JDLI-1. That is the manufacturer part number for the direct burial lay-in grounding clamp covering 10 through 2 AWG. Country of origin is Hungary.
