How are plug fuses of 15 ampere and lower rating identified?

Plug fuses rated at 15 amperes and lower are identified by a hexagonal configuration. This unique shape is standardized to help users easily recognize the fuse's amperage rating and ensure proper replacement when necessary.

The hexagonal design differentiates these lower-rated fuses from those of higher amperage ratings, which typically have different shapes. This recognition is crucial for maintaining safety in electrical systems, as using a fuse with an incorrect amperage rating can lead to hazards such as overheating or electrical fires.

Understanding these visual cues ensures that individuals can confidently identify the appropriate fuse for various electrical applications, especially in residential or commercial settings where multiple types may be encountered. Proper identification aids in adherence to safety standards and helps prevent electrical mishaps.
