Installed a dedicated 20 amp. GFCI circuit in kitchen. Used GFCI breaker in panel. Inspector tested it with plug in circuit tester and it did not trip. Breaker does trip with test button. I checked everything and I'm sure the wiring is correct. I noticed that instructions with breaker recommends to test with button on breaker. Is it possible that the plug in tester just won't work with GFCI breaker?
