Power distribution unit (PDU)

Use of electrical energy is ubiquitous in almost every aspect of life. Power distribution systems or grids provide electrical energy to households, businesses, manufacturing facilities, hospitals., etc. Industrial power distribution systems commonly divide incoming power into a number of branch circuits. The branch circuits supply power to various equipment in the industrial facility. Circuit breakers are typically provided in each branch circuit to facilitate protecting equipment within the branch circuit. In the distribution of electric power, distribution blocks are often employed. These assemblies have widely been used for distributing incoming electrical power to a number of distinct circuits. Typically the block includes a connection for a larger conductor cable or bus and a plurality of tap connections for smaller conductors. The bare ends of the conductors are inserted in socket ports or holes and held in place typically by a clamp or binding screw threaded in a hole perpendicular to the socket receiving the conductor. Many types of power distribution units (PDUs) are available for distributing power to components in environments such as, for example, data centers, computer rooms, and communication centers. A power distribution unit comprises at least one distribution point for the power supply, and at least one female outlet on its side designed to receive a male connector of a cable of an electrical device, at least one circuit breaker comprising a respective push button for resetting it. Circuit breakers are designed to open and close a circuit by non-automatic means and to open the circuit automatically on a predetermined over-current without damage to itself when properly applied within its rating. The distribution point is electrically connected by means of a respective electrical cable to a manually resettable circuit breaker. A circuit breaker is connected by means of an electrical cable to at least one female outlet. Often an uninterrupted power supply (UPS) is utilized for the central power supply so that continuous, uninterrupted power can be supplied to the power distribution system and ultimately to electronic components. As can be appreciated, the disruption of power to the electronic components, such as rack mounted computer systems, can often be disastrous.
