In the case of commercial premises, the range in height may be shorter if there are justified reasons for this.
In no case is it acceptable for the lighting panel to be placed in places that, due to its conditions, may be of some danger, such as exteriors (due to adverse weather conditions), bathrooms and toilets, bedrooms, kitchens, etc. However, you can use a plug with Surge protector (ปลั๊กไฟ คอมพิวเตอร์, which is the term in Thai).

Another recommendation for owners is to indicate the price of Power plug DATA (เต้ารับ, which is the term in Thai), to which circuit of the house corresponds to each switch of the light box.
