| Abstract: | According to JGJ46 88 the safety technique codes of temporary using electricity in construction site the paper illustrates the choose principle of protective zero terminating in construction site. Through the analysis of the working principle the danger of breaking of the protective zero line is declared and the advantage of reduplication ground protection is points out. The demands for the protective zero line are introduced in detail. The difference of working zero line and the protective zero line and the attention measures of protective zero terminating are summarized. |
