| Abstract: | Analysis is made on clauses 3. 1.3, 3.2. 14 and 6. 4. 3 of Code for Design of Low Voltage Electrical Installations （GB 50054- 2011）, which are controversial in understanding and execution, by making reference to IEC standards. Related requirements on electric isolation are discussed by taking most widely applied TN system as an example; electric principles are sought after by taking terms in the design codes as clues; and requirements and progresses made in electric fire prevention in IEC standards are introduced. |
