Why must circuit breaker be hooked in series with a line of appliance even though the line of appliances are hooked together in parallel?

So like someone else said in America they each have their own breaker, when you refer to parallel and series, I’m guessing you are referring to how multiple appliances are hooked up to one circuit in a parallel and the breaker is series. Another reason that hasn’t been stated is for the over current protection. Take a wall of 120 volt receptacles that are all on the same circuit in parallel, when one of the plugs goes bad or stops working for a reason that isn’t a short or over current, the rest of the plugs keep working, if they were in series when one stops they all stop. Now this is why your breaker is wired in series so when an over current or short happens the breaker shuts everything down instead of continuing to supply power to a malfunctioning device, if not it is very probable that an electrical fire is in your future.
