M & E system is divided into four main categories:

1. Ventilation systems and air-conditioning (Heating Ventilation Air Conditioning, referred to as HVAC)

2. Water supply and sanitation (Plumbing & Sanitary, referred to as P & S)

3. Fire alarm and fire fighting system (Fire alarm & Fire fighting)
4. Power System (Electrical)

In the four items above, the electrical system accounted for about 40-60% of the volume of M & E (Depending on the project, even up to 70.80%).

And it is divided into two categories as follows:

Farad

1. Main power supply: the main power supply system, including the high-voltage, medium-voltage lines, machine transformer 24kV/0.4kV and the main switching cabinet (call is MSB, main switch board)
There may be additional (automatic voltage regulation system: Automatic Voltage Regulator System, referred to as AVR)
2. The system of power distribution cabinet: Submain power supply (including power dynamics, production, lighting, sockets, etc.)
3. Living lighting system: Lighting
4. System socket: Socket outlet
5. Lighting system problems: Emergency lighting (exit lights, emergency lights)
6. System earthing: Earthing system (or grounding system)
7. Lightning protection system: Lightning protection system (including the earthing poles and metal lightning, earthing system)
