True or False: When an overcurrent caused by a fault occurs, the fuse element melts, opening the fuse holder portion of the cutout.

The statement is true because when an overcurrent occurs due to a fault in an electrical circuit, the designed function of a fuse is to protect the circuit from damage by interrupting the flow of current. The fuse element, which is made of a material that has a specific melting point, heats up due to the excessive current. Once the current exceeds the rated capacity of the fuse, the element melts, effectively creating an open circuit. This action trips the fuse holder portion of the cutout, thereby preventing further current from flowing and protecting the rest of the electrical system from potential damage, hazards, or fire caused by the overcurrent situation. The fuse’s ability to respond to overcurrent is a critical safety feature in electrical distribution systems, ensuring that equipment and wiring are safeguarded against overload conditions.
