A distribution box, also known as a fuse box or power distribution box, is the heart of the domestic electrical installation. It is used to distribute the electricity supplied by the energy supplier to the various circuits within a building. It helps organize, protect, and control electrical connections in residential, commercial, and industrial electrical systems. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV. The distribution of electrical power is the final and most important step in the journey of electricity from generating facilities to consumers.
