What are the differences between a 15 amp and a 20 amp GFCI outlet in terms of their electrical capacity and functionality?

A 15 amp GFCI outlet can handle up to 15 amps of electrical current, while a 20 amp GFCI outlet can handle up to 20 amps. The main difference is their capacity to handle higher electrical loads. Additionally, a 20 amp outlet is typically used in areas where heavy-duty appliances are plugged in, while a 15 amp outlet is more common in standard household applications. Both outlets provide ground fault protection to prevent electrical shocks.
