 Abstract：This paper briefly describes the requirements of relevant codes for diesel generator unit emergency start access,and discusses the rationality and applicability of the requirement that the generator start signal“must be sent by the auxiliary contact of the main switch of normal power supply”in clause 4.0.2 of the Code for Design Electric Power Supply Systems(GB 50052 - 2009). This paper briefly discusses the connection mode of emergency generator start signal and its coordination with diesel generator start controller in common single and double mains power supply electrical systems in building electrical works, and puts forward some suggestions.
