What is a sub-distribution board
The sub-distribution board is used when a part of the installation is located far from the main distribution board or requires separate distribution and protection.
When is it used
- On another floor.
- In a garage or storage room.
- In an external building.
- In a space with many independent loads.
What needs to be calculated
The supply line for the sub-distribution board must be calculated based on the total load, length, voltage drop, and cable protection.
Important
The sub-distribution board should not be connected haphazardly from a random line. It requires proper power supply, grounding, and coordination of protective devices.
