ABSTRACT:The design of national building electrical relevant specification criteria for the safe, with electricity, energy saving for the premise, focus on improving quality of power from the masses of users, reflect the rich and well-off social material the happiness of life, applied modern electrical technology, completed YunXiJun garden district commerce-residence building of distribution, power, grounding lightning protection, the household table engineering and equipment selection and calibration. . 

　　　In distribution design, according to load level, to determine the power-supply modes and system solutions; In the design of a table set by one household metering, automatic meter reading of power-supply modes, to ensure the precision and reliability of power supply ; Use need coefficient method for calculating load, according to the regulation choose to defend appliance, wire and cable, achieve security and energy saving electricity purpose; For electric equipment check and reasonable design according to the requirement was lightningproof grounding .

　　　Using AutoCAD drawing software draw design drawings and use HaoChen and TianZheng to help design.
