According to the requirement of "notice on printing and distributing < the plan for
preparation and revision of national standards of project construction years 2000 to 200 I>"
(Jianbiao [200l]No.87) issued by the Ministry of Construction, this Code is prepared based on the
revision of "Standard for Inspection and Assessment of Construction Quality of Electrical
Installation in Building" GBJ 303-88, "Code for Construction and Acceptance of Wiring Works
for Electrical Installation Project of lkV and Below" GB 50258-96, and "Code for Construction
and Acceptance of Electrical Lighting of Electrical Installation" GB 50259-96 by the chief
editorial unit, Zhejiang Kaiyuan Installation Group Co. , Ltd (formerly called Zhejiang Industrial
Equipment Installation Co.,), jointly with other units under the organization of Zhejiang Provincial
Construction Department.
During the preparation of this Code, the editorial group has carried out extensive
investigation and research; has carefully summarized the practical experience in control and
acceptance of construction quality of electric installation in building in China, has kept in line
with "Uniform Standard for Acceptance of Construction Quality of Building Project" GB
50300-2001 in the principle of "separation of inspection and assessment, intensification of
acceptance, perfection of manner, control of process", and has extensively collected the

finalized in Oct. 200 L
This Code is of mandatory standard that contains mandatory clauses, which emphasizes
on ensuring project safety, application function, human health , environment benefit and
public benefit, and specifies the control and acceptance of construction quality of electrical
installation in building, and also properly specifies a few requirements on appearance quality.
This Code may be subject to partial revision in the future, which will be publicized on
the magazine of"Standardization of Project Construction".
Those clauses that are printed in bold are mandatory clauses, which must be forced
In order to improve the quality of this Code, the users of this Code are kindly required to
summarize experience and accumulate data, and send any suggestion or comment to Zhejiang
