The fused connection units - spurs - are used to connect permanent appliances (like the washing machines, single ovens, dishwashers, extractor hoods and fans, etc) to the electrical circuits of the house. They are also called "spurs" - they are not a socket; a FCU (fused connection unit) "diverts" the electricity to an electrical appliance. It has to have a fuse, otherwise the 32A electrical current taken from the consumer unit can melt the cable, and this can cause a fire. The 13A spurs are in a brushed steel finish(also called brushed chrome finish, stainless steel finish or satin nickel finish).
