     DETAILED DESCRIPTION 
     A detailed description a particular illustrative embodiment of the invention will now be provided. The purpose of this detailed description, which includes the drawings, is to satisfy the statutory requirements of 35 U.S.C. § 112. For example, the detailed description includes a description of inventions defined by the claims and sufficient information that would enable a person having ordinary skill in the art to make and use the inventions. In the figures, like elements are generally indicated by like reference numerals regardless of the view or figure in which the elements appear. The figures are intended to assist the description and to provide a visual representation of certain aspects of the subject matter described herein. The figures are drawn to scale, the figures do not show all the structural details, nor do they limit the scope of the claims. 
     Certain specific embodiments of methods, structures, elements, and parts are described below, which are by no means an exclusive description of the inventions. Other specific embodiments, including those referenced in the drawings, are encompassed by this application and any patent that issues therefrom. 
     A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power. 
     In a particular illustrative embodiment of the invention, a power distribution unit is provided constructed of galvanized steel. In a particular illustrative embodiment of the invention a Power Distribution Unit (PDU) for Crypto Mining Applications is disclosed. In a particular illustrative embodiment of the invention each power strip section provides six (6) 240 VAC outlets. The incoming power is three phase power, led to a 45 AT three-pole breaker. Cabling distributes 240 VAC single phase power to the outlets. 
     In addition to this, the power strip is equipped with a 20 A 1 phase miniature circuit breaker for each outlet. Cable is provided to the line side of the 45 AT breakers on each power strip. Each cable has a 3 foot service loop for each power strip. Each busduct is constructed of galvanized steel, with a width and depth as set out in the attached drawings. Final height of the raceway is to be determined. Holes in the side of the raceway shall be designed so that the power strips securely mount to the raceway while sealing the power cable in. 
     The power distribution unit is constructed of galvanized power strip section is constructed of cold rolled steel and has six (6) 240 VAC outlets. The incoming power is 415V three phase power, led to a 45 AT three pole breaker. Cabling will then distribute 240 VAC single phase power to the outlets. In addition to this, the power strip shall be equipped with a 20 A 1 PH miniature circuit breaker for each outlet. The power strip is furnished with hinges to attach to upper shelf of the mining cabinet. Height of the power strip shall be no greater than four (4) inches. The length of the power strip shall not exceed 36 inches. 
     A steel raceway for 415V three-phase power cables is provided. Cable included from the terminal block at the base of the raceway to the line side of the 45 AT breakers on each power strip. Cables run from the terminal block, make a service loop in the raceway, and then connect to the 45 AT breaker in each power strip, for a total of seven (7) cables enclosed in each raceway. Each cable will have a 3 foot service loop for each power strip. In addition to this, EPD shall also provide cables to connect each feeder breaker on the MDP to each raceway terminal block. This consists of one (1) 480+VAC 300+A rated cable per raceway. 
     Each raceway shall be constructed of cold rolled steel, with a width and depth no greater than 6″×6″ respectively. Final height of the raceway is to be determined. Holes in the side of the raceway shall be designed so that the power strips securely mount to the raceway while sealing the power cable in. The cables will be secured at the junction from the power strip to the raceway using a strain relief design.
