    Electrical Distribution board Q

    Electricians

    I’m in the process of getting three phase supply put in, SSE have advised I’ll need to have distribution/supply board setup for when they lay the cable.
    My question on is, what type of board to I need, they mentioned it would probably be on a concrete plinth and on a wooden back board.
    Looking for advise on all this please
    (I’m in the process of trying to find tradesmen to do all the excavation and electrical work)

    "You will need a 5core SWA armored cable, 3 phase distribution board, with a 3-inch backboard on top of a 2×4 timber."

    "Generally, you put a DB on a block wall for two reasons
    1) mechanical integrity
    2) fire containment, domestic boards are put on wood for ease of fixing for the network provider or meter company
    who ever is designing and calculating the system should specify this, also, it should be a fireproofed cupboard with a lock and heat sensor
    when you calculate you should forecast for additional circuits, and also a surge protection device,
    I am an electrical designer eng and inspector, an electrician should be able to do this, TPN (three-phase and neutral ) boards start at 100 amp per phase,
    If you're laying a cable in the ground for supply then SSE have set criteria under ESQCR, BS62305 is the lightning protection regulations, Part B is building regs for fire, BS7671 is elec regs,
    As this is not domestic the SSE will require a DEAD TEST before connection to a meter.
    Hope this helps."
