Do you check for this? (2002 NEC)
440.65 Leakage Current Detection and Interruption (LCDI) and Arc Fault Circuit Interrupter (AFCI).
Single-phase cord-and-plug-connected room air conditioners shall be provided with factory-installed LCDI or AFCI protection. The LCDI or AFCI protection shall be an integral part of the attachment plug or be located in the power supply cord within 300 mm (12 in.) of the attachment plug.
Generally, portable room air conditioners are used only on a seasonal basis and are removed and stored at the end of the cooling season.
During the life of a room air conditioner, the installation and removal occurs many times, and there is an increased likelihood of a damaged cord as a result of the unit being set on the cord or pushed against it. To provide enhanced protection against fires initiated by damaged supply cords, all single-phase cord-and-plug-connected room air conditioners are required to be equipped with either leakage current detection and interruption protection or arc-fault circuit interrupter protection. The protective device is required to be installed in the appliance cord and must be within 12 in. of the attachment plug.
