Dear Mr Smith, In order to provide the short circuit calculation as required, we have analysed, some more reference and data are needed. For example, relevant parameter of generator, the specification and length of cable from generator to patching panel and from patching panel to distributor block(分电箱供参考). Could you please advise? Thanks so much for the work you have done, looking forward to hearing from you soon. RegardsXXX(另外, 如果楼主知道, 请将分电箱的英语单词附上, 以供大家学习) 我觉得是不是指的是变压器啊? 除了distributor block , 可否用 transformer ? 望告知。谢谢
