Abstract:
A system and method include a ground fault circuit interrupter (GFCI) supplying electricity to an appliance. The GFCI supplies direct current (DC) to an appliance upon connection to the GFCI, and the appliance automatically communicates data to the GFCI prior to startup of the appliance in response to receiving the DC, wherein the data describes maximum out of phase conditions expected during appliance startup, and the GFCI acknowledges receipt of the data. The appliance sends a status message to the GFCI indicating the appliance is ready for alternating current (AC) in response to the startup of the appliance, and the GFCI switches from supplying the low voltage direct current to supplying AC to the appliance in response to the GFCI receiving the status message. The method further comprises preventing the GFCI from tripping in response to out of phase conditions less than the maximum out of phase conditions.
