An interesting
Article from NEC digest here stating new GFI requirements.
Six revisions to the UL requirements for the GFCI have been drafted and will become effective January 2003. They include:
~A more stringent voltage surge test to ensure the GFCI can handle a higher surge current.
~A new corrosion test to demonstrate greater immunity to moist conditions.
~An operating test to verify that proper operation of the GFCI can not be prevented by manipulation of the GFCI controls.
~A reverse line-load miswire test that requires the GFCI to trip when miswired.
~An abnormal overvoltage test that requires the GFCI not become a fire or shock hazard during extreme overvoltage conditions.
~Increased requirement for GFCI to operate properly after exposure to conducted radio frequencies.
