Breakaway extension cord for preventing electrical plug damage

A method of coupling a mobile, electrically powered floor engaging appliance having an elongated electrical power cable terminating in an appliance male connector with a normal stationary electrical outlet receptacle in order to prevent significant damage to said appliance male connector in the event that an undue tension load is experienced by the power cable during movement of the appliance, said method comprising the steps of:

• providing a short electrical extension cord presenting a stretch of flexible electrical cable, a female electrical receptacle operatively coupled with said extension cord at a first end of the cable, and an extension cord male electrical connector having a mating configuration with said female electrical receptacle at a said second end of the cable, said male electrical connector being adapted for insertion into said stationary electrical outlet receptacle, wherein said short extension cord has a maximum length of up to about 8 inches;
• inserting said extension cord male electrical connector into said stationary outlet receptacle;
• and
• inserting said appliance male connector into said female electrical receptacle of said short extension cord,
• said appliance male connector being separable from said female electrical receptacle by an undue tension load that turns and twists said female electrical receptacle prior to separation of the extension cord male electrical connector from the stationary electrical outlet when the mobile, floor engaging appliance is pulled at an angle to the stationary electrical outlet receptacle under said undue tension load.
