Number of appliances on one radial line

Former Community Member
Former Community Member
Hello all,  I would really like some advice/reassurance.  We are having our kitchen done and the existing wiring is a radial line.  The builders are installing a 2.5mm TE line which services a double socket (coffee machine), dishwasher, boiling water tap and washer dryer.


My concern is that a single radial line is insufficient for the loading s involved.


I would really appreciate your thoughts.

    BOG STANDARD answer.

    without derating a 13KW load for a traditional cooker on a 6.0 T & E cable is ok for a traditional cooker (oven, hob, grill) on a 32A MCB or a 30A rewireable fuse and if you add a socket for a kettle you`d deduct 5 amps from the 13KW (not the fuse or MCB rating) so you are still within.


    For a normal domestic circuit based on two adults and 2.4 children.

    Of course an industrial kitchen with lotsa usage takes more thinking about.

    So unless the manufacturer actually states other things then the two things in combo don`t add up excessively more than one traditional old fashioned cooker but in your case housed in two units not one unit.
