Leak-current Detection and Interruption (LCDI) Plugs
Because portable air conditioners have caused many electrical fires, those sold in the United States now must have leak-current detection and interruption (LCDI) plugs. The cords have a fine wire mesh around the conductors and circuitry to detect any current leaking from the conductors to the mesh, which would happen if the cord were damaged or frayed. These could be NEMA 5–15, 5–20, 6–15, 6–20 or 6–30 plugs, depending on the air conditioner. The plug is equipped with "Test" and "Reset" buttons on the housing.

Famous quotes containing the word interruption:
““... We need the interruption of the night
To ease attention off when overtight,
To break our logic in too long a flight,
And ask us if our premises are right.””
—Robert Frost (1874–1963)
