Just wondering what other inspectors/localities are getting if/when GF testing is required per 230.95(C)
To be honest many of our local electrical contractors have never heard of it or been required to do the tests. Just asking if this is common across the land.
Thanks

It seems many of our contractors use the simple 'push to test' button.
It also seems many of our AHJ's do not accept the 'button test' as meeting the 230.95, so they are denying 'occupancy permits' to the building.
On the contrary, the current flowing in the test resistor does not directly activate the release coil. It provides a test imbalance in the sensing coil which is indistinguishable from a leakage imbalance. That tests the sense amplifier as well as everything after it.That test button is a hack. There's an internal resistor between the load side hot and line side neutral. Pressing the button makes the circuit. You're only testing the internal coil and release mechanism; you're not testing the circuit.

No. I was referring to the rest of the mechanism in the GFCI device beyond the sense amplifier. Such as the release coil and moving contacts.That's how I understood it. You word things better than me.
But you got me there. Are you saying that popping that test button affirms there are no crossed/ open/ etc neutrals, etc. downstream on the branch circuit?
