Top-Quality NEMA Power Cords
Most consumer electronics have straight blades, and the metal conductive blades are called "prongs" informally (3-prong power cord, for example). Except for grounding connectors, NEMA straight-blade connectors have blades that are flat or folded. In industrial applications, locking connectors have curved blades that allow the plug to be twisted and locked into the outlet. These locking mechanisms provide additional safety and security in environments where power needs to be kept on for long periods of time.

NEMA Plugs and Plug Adapters
A NEMA 5-15P is a three-prong grounded plug that plugs into a standard 110 VAC wall outlet. A NEMA standard is set by the National Electrical Manufacturers Association, an industry group. There are two flat parallel blades on the connector, with a round ground pin above and between them.
Plugs that fit into 110 VAC wall outlets are commonly referred to as NEMA 1-15Ps. The plug has two flat blades, just like the NEMA 5-15 plug, but there is no ground pin. A 1-15R (receptacle) is the female mating outlet for the 1-15P. This plug has a slightly wider blade on one end than the other on most current versions.

Frequently Asked Question
In North America, power cords are commonly governed by the NEMA and IEC standards. A NEMA connector is found on the side of the power cord that plugs into an AC wall outlet. IEC connectors are international standards that are also widely used in the US. Devices such as computers and televisions use IEC connectors. Power cords with IEC receptacles and NEMA plugs are common.
NEMA plugs by itself may or may not be part of a waterproof electrical system. There are a number of locking NEMA receptacles and plugs for industrial use that can be waterproof. For instance, a NEMA receptacle with weatherproof flanged inlet can create a seal with a properly rated and matching plug. These watertight devices are used in harsh environments such as water treatment, agriculture, food and beverage processing, outdoor entertainment, and factories.
It depends on the rating of the NEMA cord. NEMA cords can be used both indoors and outdoors if it has a rating of W-A or W. W-A and W are rated for outdoor use as they are weather and water resistant.
