70% to pass

The purpose of fuses in electric wiring is to _______________.

A permit the use of smaller wiring for lighting circuits
B reduce voltage to the branch circuits
C prevent overloading the circuits
D allow for cutting out branch circuits
AI Explanation

The correct answer is C) prevent overloading the circuits. Fuses are designed to protect electrical circuits from excessive current flow, which can lead to overheating and potential fire hazards. When the current in a circuit exceeds the fuse's rated capacity, the fuse will "blow" or open the circuit, interrupting the flow of electricity and preventing damage to the wiring and connected devices. This is the primary purpose of fuses - to act as a safety mechanism and prevent overloading of the electrical system. The other options are incorrect because they do not accurately describe the main function of fuses. Option A is about using smaller wiring, which is not the purpose of fuses. Option B is about reducing voltage, which is not the primary role of fuses. Option D is about disconnecting branch circuits, which is not the primary function of fuses in an electrical system.
