Answer for USA, Canada and countries using similar 60Hz household electricity supplies
If the socket outlet or plug-point is part of the house wiring and is 4-prong (4-wire is the proper term) then you MUST purchase a 4-wire cord and plug for the appliance and change it out. Most home stores (Lowes, Home Depot) sell these cord and plug sets just for that reason.

How to install the new cord To upgrade your appliance, go to the hardware store and buy a new 4-prong 110/220V cord with a ground that is the right size in amperage for the appliance. 30A for dryers, 50A for ranges. Remove the old cord, and install the new cord. If the old cord was flat without a color code, the two outside wires are the hots (red and black on the new cord) and the center wire is neutral (white on the new cord). If the neutral lug is bonded to the chassis, break the bond. The green wire in the new cord grounds the chassis. Connect the green wire to a convenient screw in the chassis, if a dedicated green ground screw is not provided.

Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized
