NEMA 14-50 Outlet and Plug: This is a four-prong outlet rated for 125/250 Volts, 50 Amps. It has two hot wires, one neutral, and one ground. The design includes two vertical blades for the hot wires, one L-shaped blade for the neutral, and a round or U-shaped pin for the ground. This type of plug is often used for larger appliances such as electric stoves, ovens, and electric vehicle charging stations.

NEMA 6-50 Outlet and Plug: This is a three-prong outlet rated for 250 Volts, 50 Amps. It has two hot wires and one ground, but does not include a neutral. The design includes two vertical blades for the hot wires and a D-shaped pin for the ground. This type of plug is often used for welding equipment and other heavy-duty industrial tools.
