I installed new GFCI. It’s the last outlet in that circuit so I connected the wires without touching the yellow sticker. After all done, I tested it and green indicator light is solid. When I plug in, no power on both outlets. What did I do wrong?
Update. I use this GFCI outlet for portable under sink water heater. I test with a radio and it works but I plug the water heater and no power. I mean no power from outlet, not only water heater. I use the non contact tester which can test power and current. I switch to radio and has power again.
