    rcbo's for comercial kitchen

    Hi while working in a local restaraunt i noticed there is no rcbo's or rcd's protecting the kitchen. am i right in thinking all circuits in the kitchen and cold store should be rcbo protected? also toilet hand driers, sockets in the bar and also outside water feature.
