What is the function of a Cutout in electrical systems?

• A. To increase electrical load on a transformer
• B. To protect against current surges and overloads
• C. To facilitate manual switching on and off
• D. To monitor electricity flow levels

Answer: (B)

A cutout serves an essential role in electrical systems by protecting against current surges and overloads. It is essentially a fuse or circuit protection device that ensures the safety and reliability of the electrical system. When an overload or fault condition occurs, the cutout automatically disconnects the affected part of the circuit to prevent damage to equipment and maintain system stability. This protective function is critical, especially in systems like overhead power lines where they can be exposed to various environmental conditions that might lead to faults. The design of the cutout allows it to operate under high fault levels, ensuring that the more sensitive equipment downstream does not experience damage from these surges. Options that involve increasing electrical load, manual switching, or monitoring electricity flow levels do not accurately describe the primary purpose of a cutout. The cutout is specifically designed for protective functions, making option B the most relevant and accurate description of its function within electrical systems.
