What Is A 5-20R Receptacle: Introduction & Uses
Shopping for an electrical receptacle, commonly known as a power socket or outlet, requires the same amount of due diligence as shopping for electrical cables and cords. Naturally, you’d start by understanding the amount of electrical current the receptacle can handle. The current rating of an electrical outlet mainly depends on the current rating of the appliance served and the cords plugged into the socket. Besides a receptacle’s current carrying capacity, design is another crucial factor while shopping for these devices. The socket should be compatible with the types of plugs used in it. Before buying a power socket, other significant aspects include the brand and retail price.
The NEMA 5-20R receptacle is fast gaining traction as one of the go-to sockets. This post looks at the meaning of the 5-20R receptacles and why you should consider switching your standard power sockets for this product. A NEMA 5-20R is a NEMA-approved straight-blade, 125-volt, 20-amp receptacle. But to fully understand what this receptacle is, it’s essential to break down the two main parts constituting the word – NEMA and 5-20R.
