What is the purpose of fitting fuses in electrical circuits?

• To protect the wiring and equipment by limiting the current flow in case of overload or short circuit.

• To increase current flow in case of overload or short circuit and to protect electrical equipment.

• To prevent or minimise the risk of electrical shock and to protect electrical equipment.

• To decrease current flow in case of overload and to protect electrical equipment
