The most frequent mistakes made when installing a GFCI outlet include reversing the incoming power feed wires by attaching them to the LOAD terminals instead of the LINE terminals, swapping hot and neutral conductor positions, and failing to connect the bare copper ground wire to the green grounding screw. Another common error is removing the yellow protective tape from the unused terminals without realizing how improper downstream wiring disables trip protection. Verification: Use a plug-in circuit tester to verify correct wiring polarity and confirm that pressing the TEST button immediately cuts off electrical power.
