When I first started looking for a Nema 5-20P extension cord, I wanted to ensure I understood what it actually meant. The Nema 5-20P is a type of plug that can handle 125 volts and up to 20 amps. This makes it suitable for heavier appliances like power tools and other high-demand devices. The “5” indicates it’s a grounded plug, which is crucial for safety.
