A sub main is a distribution board fed from the main distribution board panel normally protected via a CPD.
The "2-deep" rule means that a building should have only the main distribution and the intermediate distribution that feeds the horizontal distribution to the work area.
Distribution boards, also known as panelboards or breaker panels, come in several types, including main distribution boards (MDB), sub-distribution boards (SDB), and consumer units. MDBs manage electricity distribution from the main supply to various circuits, while SDBs distribute power to specific areas or loads within a building. Additionally, there are specialized boards like lighting distribution boards and motor control centers (MCC) for specific applications. Each type is designed to ensure safe and efficient management of electrical distribution.
Distribution bars allow a vehicle to pull more weight without damaging the rear axle or interfering with steering. They function by adding some leverage to both sides of the hitch, which allows for more even distribution of the load's weight.
No, it was taken over by the Government of Madras State by an Enactment in 1954 and became part of the Madras State Electricty Board (now Tamil Nadu Electricity Board) circa 1957-59.

yes no problem

Main distribution board
MDB= Main Distribution Board, it is usually fed from a substation and supplies electricity to a Sub Main Distribution Board ( SMDB ) The SMDB goes on to supply electricity for a panel
A distribution board which has 7 segments , one for Main incomer, three as sub incomer for each phase and three for singlephase outgoing is called a 7 segment DB
distribution board
power distribution board
It is a device that carried various sizes of fuse to supply power to different areas of the building respectively.
The switch turns the supply on and off whilst the distribution board takes the incoming supply and separates it into the various loads - lighting, cooker, shower, sockets, etc. In modern domestic electricity supplies the distribution board usually incorporate a mains switch but in the earlier days of electricitythe switchwould be mounted separately from the 'fuse box' because the materials used were quite bulky in comparison to modern alloys and plastics.
They can come in the top or bottom whichever is the best. <<>> If the distribution panel is a load center (no Main disconnect) the above statement is true. If the distribution panel is a combination panel (main disconnect at top of panel) then the load feeds can only be brought in the two sides and the bottom. A combination panel has an internal barrier to separate the main disconnect from the load side of the distribution board.
