Ground-fault protection exists because small leakage currents near water or damp environments can become dangerous fast. Code cycles evolve — if you are comparing quotes, ask whether the scope includes bringing branch circuits up to current standards where walls are opened.
High-frequency locations
Kitchen countertop circuits, bathroom receptacles within zones, garage receptacles, unfinished basement areas, laundry utilities, and exterior outlets are common GFCI homes. Deck and pool equipment often need GFCI protection ahead of the load — not only at the device.
Test buttons matter
Monthly test cycles catch stuck mechanisms. If a device fails to trip during testing, replace it — paper labels on panels help homeowners remember the circuit map after we leave.
