I'll try. An electrician could run a single 30 or 50 amp 230 volt line (depending on the capacity of the particular appliance center) from an older home's fuse box up or over to the kitchen to a point over the counter. That line is wired into this box where it is split into multiple 15 or 20 amp 115 volt circuits for high amperage drawing countertop appliances like electric skillets, deep fryers, toasters, broilers, etc. In a building already built, running one line through a wall is easier and cheaper than running 5. One 230 volt circuit in an older fuse box takes up less space than 5 individual 15 or 20 amp circuits. Some of these centers had the capability to offer timer control for small appliances. Finally, these kitchen centers had the names of small appliance makers on them like Westinghouse and Sunbeam so that when it came time to boy a small appliance, they would have a brand name almost imprinted in their minds.
