The electrical power plug B - All you need to know.

Type B power plug, also known as the North American grounded plug, is similar to Type A but with an added third pin for grounding. It is used in North America, Central America, and parts of South America for electrical appliances and devices that run on 110-120V AC power. This type of plug is standardized by the National Electrical Manufacturers Association (NEMA) and is referred to as NEMA 5-15. Type B plugs have a maximum current rating of 15 amps and are polarized, meaning that they can only be inserted in one orientation into a receptacle. They provide improved safety by reducing the risk of electric shock and are commonly used for appliances that have metal parts or that may generate sparks, such as toasters, coffee makers, and vacuum cleaners.

FAQ

Is plug type B grounded?

Type B power plugs are typically ungrounded. They have two round prongs and do not have a ground prong. This means that they do not provide the same level of safety as grounded plugs and may pose a greater risk of electric shock. However, it is important to note that this information is a generalization and may not hold true for all regions that use Type B plugs. The electrical infrastructure and regulations of a specific country should be consulted to determine if Type B plugs are grounded or not. In general, it is recommended to use grounded plugs whenever possible to reduce the risk of electric shock. If an appliance is designed to be used with a grounded plug and is used with an ungrounded outlet, the appliance may not work properly or may pose a safety hazard.
