I would very definately recommend replacing all GFCI recepticles in the residence after having an event such as this.
My additional recommendations for the ultimate protection against this type fasilure is as follows:
1. Replace all existing GFCI recrepticles with Hubbell, Leviton or P&S brand devices purchased only through a local electrical supplier in the area and not the local hardware store, Home Depot or Lowes.
2. Install arc fault breakers on each circuit supplying the GFI recepticles and on all other 120 volt circuits supplying recepticles and lighting in the residence.
3.The 2008 NEC has expanded requirements for arc fault protection on additional circuits in new residences. Although upgradeing of existing residences is not required by the NEC it would be provide a higher degree of protection against this type failure in the future.
