All I want to mount a quick connector for my generator ground wire.

Would a Dinse 10-25 panel mount connector work or is there a better option?

Note the wall is brick/rock.

I suggest you check with a local electrical inspector to see if it meets code requirements. I doubt you can legally put a quick disconnect on a ground cable.

@dieselscout80 I'm confused.

What are you trying to quick connect?

How big is your generator, and how is it connected to the house wiring?

Do you have a ground rod driven for your generator, and you want a connector for the rod to generator wire?

As a general practice, bolting the ground wire to the rod with a ground clamp is the general method. It is a life-safety item that one doesn't want the safety ground to come apart due to vibration or other issue.

All the best, Peter

I should have said it’s the wire for the ground rod.

Our 12k generator connects to the house with a 50 amp plug.

Sorry, this is a bit of a complicated area.
(I'm not a licensed electrician, but I do wrangle cattle, I.e. no electrical certification whatsoever.)

1) is your generator internally neutral to ground bonded?
2) does your plug go to a transfer switch, or a breaker interlock?
3) If the plug does go to a transfer switch, does the transfer switch
a) switch the 2 hots, or
b) does it switch the 2 hots and the neutral?
4) is the ground rod specific to the generator?
5) is your 12kW double insulated?

The general practice is for portable generators not to be neutral to ground bonded when attached to homes, but neutral to ground bonded otherwise. This is a bit of a tug of war between OSHA, the NEC, and local AHJs, so your mileage will vary.

A portable generator will generally rely on the wiring of the generator cable, plug and transfer switch to the home ground for grounding. Some folks are uncomfortable with that, and drive a separate ground for the generator, and some inspectors are unhappy with that as well.

I would point you to the NEC code for grounding portable generators, and check out Mike Holt's detailed website and forums, e.g,
and local codes, e.g. Portable Generator Bonding And Grounding: NEC SDS Vs. Non-SDS Rules Made Simple
When reading the NEC, it often discusses the "grounded-conductor", which usually means a current carrying conductor connected to earth, I.e. "neutral", not to be confused with a ground wire, which is not intended to routinely carry currents.
(E.g. this, where the terms are defined at the end of the blog)

Grounding seems simple, but in my experience it is often not.

I hope that this helps. I personally would not use a DINSE connector on a ground wire as in the event of failure my life might depend on the ground wire being well connected, and I personally can foresee ways that a connector might become loose. I bolt mine. That is not a recommendation.

All the best,

Peter
