Unfortunately, I am unable to create diagrams. However, I can provide a detailed description of the schematic arrangement of the sequence of control at the intake point to the consumer's unit.
At the intake point, the electricity is received from the grid and enters the consumer's unit through the main distribution board (MDB). The MDB is the central point where all the electrical circuits are connected and controlled.
From the MDB, the electricity is distributed to various sub-circuits through circuit breakers or fuses. These circuit breakers or fuses act as protective devices that disconnect the circuit in case of an overload or short circuit.
Each sub-circuit is connected to different areas of the consumer's unit, such as lighting, power outlets, appliances, etc. These sub-circuits are further controlled by individual switches or dimmers to regulate the flow of electricity to specific areas.
Additionally, there may be a residual current device (RCD) or ground fault circuit interrupter (GFCI) installed at the intake point to provide protection against electric shock. The RCD or GFCI monitors the flow of electricity and trips the circuit if it detects a leakage of current to the ground.
Overall, the schematic arrangement of the sequence of control at the intake point to the consumer's unit involves the main distribution board, circuit breakers or fuses, sub-circuits, switches or dimmers, and protective devices like RCDs or GFCIs to ensure safe and efficient distribution of electricity within the consumer's unit.

Schematic Arrangement of Sequence of Control at Intake Point
[Image of schematic diagram]
Control Elements:
- Main Stop Valve: (A) Isolates the intake point from the water main.
- Pressure Reducing Valve (PRV): (B) Reduces high water pressure from the main to a safe level for the building.
- Check Valve: (C) Prevents backflow of water from the building into the main.
- Water Meter: (D) Measures the water consumption and records usage for billing purposes.
- Backflow Preventer: (E) Prevents contamination of the water supply from backflow caused by pressure fluctuations or cross-connections.
- Ball Valve: (F) Controls the flow of water into the building.
Sequence of Control:
1. Water enters from the main through the main stop valve.
2. Pressure is reduced by the PRV.
3. Check valve prevents backflow.
4. Water flows through the water meter to measure usage.
5. Backflow preventer protects against contamination.
6. Ball valve is opened to allow water into the building.
