The Fuse Board
The circuits delivering electricity to different parts of a house are all connected to single fuse board. This is the “brain” of the whole system. When electricity is delivered to a house, it first flows through the meter box, then is carried to the fuse board. From there it is distributed throughout the house via various circuits, hence why is it also called the ‘distribution box’. There are not circuits for every powerpoint and lighting socket in a house, rather they are grouped into different categories (for example there may be one for your hot water system, one for your stove, three for your power points, and two for your lighting).
