Interesting and sad you have to double check on eng. EE plans mostly are not that great, it’s $ per sheet. You saved someone from a change order

Here is one for Eaton CH breakers, I imagine all manufacturers have something similar. Square D has gangable ones too for the QO style.

$130? Quite the bargain!

For ONE?! You'd have to REALLY have to have one!

Yeah, I think that guy on fleabay is quite proud of it! LOL! The Square D ones are quite a bit cheaper! LOL!

Exactly, and usually the fourth circuit is from a different isolated ground panel or fed from a UPS/UPC panel.

I have seem this also numerous times and always thought it was a violation.
Forgive the highjack…”hh”.

Source 1: 3h-n-g
Source 2: h-n-IG
Don’t say you could bring a third g wire from source 2, because the factory whips have 8 wires.

If Source 2 plug hot wire faults to case…does circuit clear ?

The isolated ground is still a ground common to the other ground, it just does not rely on the conduit as a return path. If properly installed, both panel grounds are bonded. I have seen many times, the isolated ground incorrectly installed, and truly insulated back at the panel.
