Summary:An electrical power distribution unit for overload prevention and a method for preventing overload of the electrical power distribution unit. The power distribution unit includes: (i) a plurality of sockets, each socket being an electrical power outlet socket, each socket having a plurality of receptacles for receiving corresponding pins of a power plug; (ii) a mechanical disabling mechanism configured to disable each socket that is unoccupied by a respective power plug; and (iii) an excess power detector configured to detect an aggregate power drawn from the sockets. The method includes: monitoring, by the excess power detector, a first aggregate power drawn from the sockets; and determining that the first aggregate power exceeds a predetermined first threshold and in response, actuating the mechanical disabling mechanism to disable each socket that is unoccupied by a respective power plug.
