How are plug fuses rated at 15 amperes and lower identified?

Plug fuses rated at 15 amperes and lower are specifically identified by a hexagon configuration. This shape is standardized for this category of fuses, allowing for easy recognition and ensuring that they are used correctly for their intended amperage. The hexagon shape differentiates them from other amperage ratings, thus providing a visual cue to installers and electricians about the specific rating and application of the fuse.

This system of identification not only helps in preventing misuse but also promotes safety in electrical installations by ensuring that the correct fuse type is employed for the circuit being protected. The consistency of the hexagon shape across various manufacturers also aids in compliance with electrical code regulations, making it essential knowledge for anyone involved in electrical work.
