Peccavi,
What I should have said is that this switch unit is located in the kitchen and only has 4 swithches to operate dishwasher, washing m/c, fridge freezer, and emergency h/w. One of the switches has jammed and doesn't send power the the socket, just wanted to know the correct name of this particular unit. e.g. distribution board or power supply unit.
