A 15 amp outlet typically accepts plugs with two parallel slats, while a 20 amp outlet can handle more power and has a T-shaped slot. The main practical difference is their capacity for handling electricity: 20 amp outlets can power heavier equipment without tripping, making them suitable for appliances like microwaves and power tools. Ensure home circuits are rated appropriately before installation.
