In the preferred embodiment, the power cord comprises a plug having a first side with a plurality of first plug prongs extending outwardly therefrom and a second side with a plurality of second plug prongs extending outwardly therefrom. The first plug prongs are in a first prong pattern that corresponds with the first opening pattern and the second plug prongs are in a second prong pattern that corresponds with the second opening pattern. The user utilizes the appropriate side of the plug to electrically connect the dryer to the receptacle. A switch on the plug allows the user select which side is electrically activated. ## Claims ### Claim 1 A power cord electrically connected to a dryer, said power cord utilized in combination with an electrical receptacle having a plurality of prong-receiving openings disposed in one of a first opening pattern with four of said prong-receiving openings and a second opening pattern with three of said prong-receiving openings to electrically connect the dryer to said receptacle, said power cord comprising: a plug at a distal end of said power cord, said plug having a plug body with a first side defining a first side surface and a second side defining a second side surface; four first plug prongs extending outwardly from said first side surface of said first side of said plug body, said first plug prongs configured in a first prong pattern that is in corresponding relationship with said first opening pattern; and three second plug prongs extending outwardly from said second side surface of said second side of said plug body, said second plug prongs configured in a second prong pattern that is in corresponding relationship with said second opening pattern. ### Claim 2 (depends on 1) The power cord of claim 1, further comprising a switch on said plug body that is electrically connected to each of said first plug prongs and said second plug prongs to allow a user to electrically engage one of said first plug prongs and said second plug prongs with said receptacle. ### Claim 3 (depends on 1) The power cord of claim 1, wherein said first plug prongs at said first side and said second plug prongs at said second side are disposed in generally opposite directions. ### Claim 4 A power cord electrically connected to a dryer, said power cord utilized in combination with an electrical receptacle having a plurality of prong-receiving openings disposed in one of a first opening pattern with four of said prong-receiving openings and a second opening pattern with three of said prong-receiving openings, said power cord comprising: a plug at a distal end of said power cord, said plug having a plug body with a first side defining a first side surface and a second side defining a second side surface; four first plug prongs extending generally outward from said first side surface, said first plug prongs configured in a first prong pattern that is in corresponding relationship with said first opening pattern; three second plug prongs extending generally outward from said second side surface, said second plug prongs configured in a second prong pattern that is in corresponding relationship with said second opening pattern, said second plug prongs disposed in generally opposite direction from said first plug prongs; and a switch on said plug body between said first side and said second side thereof, said switch electrically connected to each of said first plug prongs and said second plug prongs to allow a user to electrically engage one of said first plug prongs and said second plug prongs with said receptacle so as to electrically connect the dryer to said receptacle. ### Claim 5 A power cord utilized in combination with an outlet having a receptacle with a plurality of prong-receiving openings disposed in one of a first opening pattern with four of said prong-receiving openings and a second opening pattern with three of said prong-receiving, said power cord comprising: a plug having a plug body with a first side defining a first side surface and a second side defining a second side surface; four first plug prongs extending outward from said first side surface in a first prong pattern disposed in corresponding relation with said first opening pattern; and three second plug prongs extending outward from said second side surface in a second prong pattern disposed in corresponding relation with said second opening pattern, wherein said second plug prongs are disposed in generally opposite direction from said first plug prongs, said power cord electrically connected to a dryer and one of said first plug prongs and said second plug prongs on said plug body are utilized to connect said power cord to said receptacle so as to electrically connect said dryer to said receptacle. ### Claim 6 (depends on 5) The power cord of claim 5, further comprising a switch on said plug body that is electrically connected to each of said first plug prongs and said second plug prongs to allow a user to electrically engage one of said first plug prongs and said second plug prongs with said receptacle.
