Don:
No problem with the internal test button on a gfci it works fine but to me it is supposed to work fine.
But when there is a fault caused by careless use, or just a fault(let me qualify this, a ground fault) pure and simple, it does not see that internal resistor but will fault to ground as I mentioned, to me it is a back-up to ensure that the device will operate as it is suppose to.
And the original question was how to test them when there is no EGC present, aside from the test-button, and especially in front of the customer it is also dramatic and they too are assured that what they are paying for will work.
That was all I was saying, just another way to demonstrate that this is a product that will function when it is supppose to.
