Sub-Main Distribution Board

Sub-main distribution boards are an essential component of low-voltage electrical power distribution systems. They receive power from the main distribution board (MDB) and efficiently and safely distribute it to the downstream panels or feeders and various loads within the facility.

At Multi-Electrical Industries, we design and manufacture and assemble sub-main distribution boards according to the highest quality and safety standards, fully compliant with IEC standards and the requirements of the Saudi Standards, Metrology and Quality Organization (SASO).

Each board is customized to the specific needs of each project to ensure reliable performance and ease of operation and maintenance.
