New Section
The section discusses the electrical installations in buildings, focusing on the installation of a building's link.
Installation of Building Link
- The building link consists of elements such as the general protection box, distribution line, meter room, individual derivations, power control switch, and control panel.
- Electricity is distributed to buildings through the company's network. The installation starts at the general protection box where the incoming three-phase current is protected by fuses.
- The incoming current at the general protection box includes three phases and a neutral wire. A connection terminal for grounding is also present.
- The main supply line connects the general protection box to the meter room where individual electric meters measure energy consumption for each household.
Next New Section
This section delves into components found in the meter room and their functions within an electrical installation.
Components in Meter Room
- Components in the meter room include a main switch for disconnecting power, metal bars for connecting phase conductors, and conversion from three-phase to single-phase supply.
- Each household receives a single phase and neutral wire from the central point. Safety measures like fuses are installed before meters to protect against overloads.
