Landscape Lamp Precautions
A) Ground protection and safety measures:
1> The grounding protection adopts the TT method, and a closed annular artificial grounding device is set around the outdoor lighting box. The spacing is 5m, the buried depth is 0.8m, and the grounding resistance is not more than 10 ohms.
2> The grounding terminals of all lamps in the system are reliably connected to the PE busbar of the lighting box after being reliably connected with the PE wire and grounded.
3> In order to prevent lightning strike and overvoltage, a first-level surge protector is installed in the outdoor lighting box.
B) Matters needing attention: It is necessary to strictly control the purchase of electrical conduits and steel pipes, and the junction box, lamp box, switch box, etc. must have product qualification certificates.
C) Precautions for installation of lamps
1> Insulation should be done well, especially in humid environments, such as bathrooms and kitchens, it is easy to short circuit if the insulation is not done well.
2> Large lamps, especially glass lamps, must use iron expansion screws (iron expansion pins) when installing the hanger. Do not punch holes first, and then screw in wooden wedges to fix them. This method only It is suitable for lateral fixing on the wall, not for the top surface. It is also not recommended to use plastic expansion tubes, because plastic expansion tubes will age over time.
3> Prepare some No. 6 screwdrivers in advance, because you will encounter such a situation when installing the lamp: when installing the chassis, because the original screwdriver is sealed at one end, it will not be screwed to a certain extent. In this case, you can screw up a No. 6 screw head and tighten it, and then screw the original screw head, which is not only beautiful but also prevents the chassis from not fully matching the top surface.
