This part of the scope GB 16915 specifies the technical requirements for the classification, marking, anti electric shock protection, structural requirements, mechanical and electrical performance of switches for household and similar fixed electrical installations. This section is applicable to manually operated general purpose switches for household and similar fixed electrical installations used indoors or outdoors, only for AC power, rated voltage not exceeding 440 V, and rated current not exceeding 63A. The rated current limit of switches equipped with threaded terminals is a maximum of 16 A. The switches covered in this section refer to the load circuits of tungsten filament lamps intended for normal use; Or - fluorescent lamp load (including electronic ballast) circuit; A substantially resistive load circuit with a power factor not less than 0.95; Or - single-phase circuits for motor loads with a rated current not exceeding 10A and a power factor not less than 0.6; Or - self ballasting lamp load circuit For example, LEDi or CFLi; or - halogen lamp load circuit; or - combination circuit of the above types. Note 1: We are considering expanding the application range to switches with a rated voltage above 440 V. Note 2: We are considering adding switches with a rated current of 10A for motor loads. Note 3: Currently, switches with a rated current greater than 10A are considered as switches with a rated current of 10A for motor loads. This section also applies to the installation box of switches, but does not apply to the installation of concealed switches Boxing. Note 4: The requirements for installation boxes for concealed switches can be found in GB17466. This section also applies to switches equipped with signal lights-- Electromagnetic remote control switch (its special requirements are given in Part 2); - Switches equipped with delay devices (special requirements given in Part 2); --- Switches with combinations of switches and other functions (but not applicable to switches combined with fuses); - Electronic switches (with special requirements given in Part 2); - Switches equipped with flexible cable retention devices and flexible cable outlet devices (see Appendix B); --- Isolation switch (its special requirements are given in Part 2). Note 5: The minimum length of flexible cables used for the above switches can be specified by national wiring regulations. Switches that meet the requirements of this section are suitable for use in ambient temperatures typically not exceeding 35 ° C, but occasionally reaching 40 ° C
Function of testing report:
