Common Electrical Installation

The electrical supply comes into the home from a pole transformer or from a line passing the house with a pole transformer somewhere along the street - or your house may be in a streetscape where the electricity comes in from underground cabling. A service fuse connects the supply to the switchboard / switch box with its power meter and main switch. From there, power is routed to the individual circuit breakers and safety switches for the different light and power circuits in your home.
