MLDB vs Other Boards

Comparison with MDB

You may wonder what makes MLDB different from a Main Distribution Board (MDB). Both boards help move electricity through a building, but they do not do the same job. MDB is the main point for all electrical loads. It sends power to many types of circuits, such as lighting, air conditioning, and sockets. You use MDB to control and protect the whole electrical system.

MLDB works only with lighting circuits. You use it to manage and protect lights in different areas. It does not handle heavy machines or other equipment. MLDB receives power from the MDB and then splits it into smaller lighting circuits. This setup helps you keep lighting safe and easy to control.

Here is a simple list to show the difference:

MDB: Handles all electrical loads in a building.
MLDB: Focuses only on lighting circuits.

Tip: If you need to control lights in many rooms, MLDB is the board you use. If you want to manage everything electrical, you look at the MDB.
