I replaced a non-protected receptacle with a GFCI type and now my circuit tester trips the GFCI as soon as it is plugged in. The receptacle tested fine before replacement, ground, neutral, hot, etc. I've double checked the hot/neutral/ground connections. I've also tried it with the downstream load disconnected.
The GFCI trips the moment I plug in my circuit tester (before pushing the test button). Otherwise things check out OK. I can plug in a power tool without it tripping. Also, the integrated test/reset button work correctly.
I've read that the integrated test button is the only one that truly matters. Is this correct or should I be concerned? I'm sure a home inspector will red flag this if their tester has the same result.
My tester is by "Commercial Electric". The tester is one of the palm sized three prong type with three leds to indicate the condition of the circuit and a button on top to test GFCI. It's new from the local box store.
