Introduction
This standard serves as a basic and directive standard for safe use of electricity. It specifies basic principles and requirements for safe use of electricity in design, manufacturing, installation, use and maintenance of electrical equipment, so as to regulate the behavior of safe use of electricity and provide safety guarantee for persons and property. Safety requirements and precautions for various electrical equipment, electrical installations and power-consuming places shall be specified in accordance with this standard.
This standard specifies the requirements for safe use of electricity in the relevant clauses with regard to characteristics and causes of common electrical accidents in the process of electricity consumption, so as to prevent or reduce electric injury, electrical fire, damages to electrical equipment and installation, etc.
In view of the different characteristics of electricity consumption in various industries, some provisions of this standard specify the principled safety requirements for normal use and management of electrical product. In actual practices, these requirements and regulations (or codes) for safe use of electricity in the relevant industries shall be followed.
General guide for safety of electric user
1 Scope
This standard specifies basic requirements for safe use of electricity at different stages in the full life cycle of electrical equipment such as design, manufacturing, installation, use and maintenance, general principles for safe use of electricity in special locations and under environment conditions, and specific requirements for persons.
This standard is applicable to various electrical equipment and electrical installations with rated AC voltage of 1 000 V or below, or DC voltage of 1 500 V or below.
2 Terms and definitions
For the purposes of this standard, the following terms and definitions apply.
2.1
electrical equipment
product or component that is suitable for electric energy application in terms of function and structure, including products related to power generation, transmission, distribution, storage, measurement, control, regulation, conversion, supervision, protection and consumption, as well as electrical equipment, electrical installation and electrical appliance in the communication technology field and those assembled by the aforesaid ones
2.2
electrical installation
combination of electrical equipment for achieving a specific purpose and of mutual coordination characteristic
[IEC 60050-826:2004, definition 826-10-01]
2.3
electric shock
physiological effect arising from current flowing through human or animal body
[GB/T 4776-2017, definition 2.1.3]
2.4
direct contact
electric contact of person or animal with live part
[GB/T 4776-2017, definition 2.1.16]
2.5
indirect contact
electric contact of person or animal with exposed conductive part which have become live under fault conditions
[GB/T 4776-2017, definition 2.1.17]
2.6
protective earthing
one-point or multi-point earthing of system, device or equipment for the purpose of electrical safety
[GB/T 4776-2017, definition 2.3.2.3]
2.7
class 0 equipment
equipment that is protected against electric shock through basic insulation, that is, there is no connection between the accessible conductive part (if any) and the protective conductor in the fixed wiring of the equipment, and it is protected depending on the surrounding environment in case that the basic insulation is damaged
[GB/T 4776-2017, definition 2.3.3.1]
2.8
class I equipment
equipment that is protected against electric shock through both basic insulation and an additional safety measure, that is, the conductive part liable to electric shock is connected to the protective (earthed) conductor in the fixed wiring of the equipment, so that the accessible conductive part will not become live when the basic insulation fails
[GB/T 4776-2017, definition 2.3.3.2]
