Ground Clamp for Conduit

[RSquirrel]

For an upcoming underground feed to an outdoor CSED, PG&E (our local electrical utility) requires a grounding clamp with an integral conduit hub (the ground wire must be encased in rigid conduit - ½” in this case). For any of the clamps I have found (e.g. T&B/Blackburn JP-12), the smallest clamped water pipe size is ½” (0.84” O.D.). I need to clamp to a 5/8” ground rod, so the smallest listed clamp will not engage with the rod’s diameter. Can anyone suggest a specific grounding clamp to accommodate a ½” RMC conduit and a 5/8” ground rod?

Are you looking for a single piece to bond a 1/2" RGC to a 5/8" rod driven right next to the conduit?

If so, you can't use two clamps joined by a jumper? Can you post a pic?

Can't post a picture, since the project has not yet been started. Yes, looking for an integrated (not necessarily one-piece) product, like that shown, except capable of gripping a 5/8" rod. The 1/2" conduit is vertical and parallel to the ground rod, offset ~1" +/-.

That's easy. Flip the lower half of the pipe clamp.

Added: That's why it's shaped like it is.

Thanks, that's genius. I wonder why the cut-sheet doesn't include that as an option. Also explains the seemingly too-long screws.

More amazingly is how often the little "trick" is not applied in the field resulting in a loose clamp.
