Electrical apparatus for switching or protecting electrical circuits, or for making connections to or in electrical circuits (for example, switches, fuses, lightning arresters, voltage limiters, surge suppressors, plugs, junction boxes), for a voltage exceeding 1,000 volts (HS 8535); Switches (ICS 29.120.40)
Draft Thai Industrial Standard for Switches for Household and Similar Fixed – Electrical Installations: Part 1 General Requirements (TIS 824 – 25XX (20XX)) (144 page(s), in English)
The Thai Industrial Standards Institute (TISI) has proposed to withdraw the Thai Industrial Standard for switches for household and similar fixed – electrical installations: general requirements (TIS 824- 2551 (2008)) and replace it with switches for household and similar fixed – electrical installations: part 1 general requirements (TIS 824- 25XX (20XX)) as a mandatory standard.
This standard covers manually operated general purpose switches, used for A.C. only with rated voltage not exceeding 440 V and rated current not exceeding 63 A. It is intended for household and similar fixed electrical installations, both indoors and outdoors. For switches provided with screw less terminals the rated current is limited to 16A.
