Which plug type is widely recognized as Type B?

Type B is widely recognized as a specific plug type that features two flat parallel blades and a grounding pin. This plug configuration is primarily used in North America and is designed to fit into Type B outlets, which accommodate the grounded design to enhance electrical safety.

The grounding pin on Type B plugs adds an important safety feature, ensuring that devices are grounded to prevent electrical shock. This grounding pin is longer than the flat blades, which means it connects first to the outlet, ensuring a safe connection before the current-carrying pins make contact.

Additionally, Type B plugs are rated for higher amperage than Type A plugs and are compatible with devices that require grounding, making them ideal for a wide range of appliances and tools. The other options provided reference different types of plugs or configurations that do not correspond to the standard Type B plug recognized in electrical systems.
