1. The insulation resistance value of the conductive part of the lamp to the ground should be greater than 2MΩ. The garden lights should be installed vertically, and lamps such as column-type street lamps, floor-type street lamps, and special garden lamps should be reliably fixed to the foundation, and the anchor bolts and caps should be complete.
2. The fuses in the fuse box of each set of lamps are complete, and the specifications are suitable for the lamps. The junction box or fuse box of the lamp, and the waterproof gasket of the box cover should be completely installed. The street lamps on the overhead line poles should be in the correct position, be fixed reliably, and have complete and tightened fasteners. Each set of lamps should be protected by fuses.
3. When garden lights and street lights on poles are installed with devices that automatically turn on and off according to the brightness of natural light, they should be debugged, and the automatic on-off power control device of the lamps should be accurate.
4. Grounding of garden lights The grounding of garden lights requires strict attention. Metal posts and lamps that are close to exposed conductors should be connected to the PEN wire reliably. The grounding line should be set as a separate trunk line, the trunk line should be arranged along the garden lights to form a ring network, and the grounding trunk line should be connected to the grounding device lead-out trunk line at no less than 2 places. The branch line drawn from the grounding trunk line is connected to the metal lamp post and the ground terminal of the lamp, and is marked. The grounding branch line of the luminaire cannot be connected in series with the luminaire to prevent the displacement or replacement of individual luminaires and the loss of grounding protection for other luminaires.
5. Power-on test run After the installation of the lamps and lanterns, the power-on test run is allowed only after passing the insulation test inspection. After the power is turned on, it should be carefully inspected and patrolled to check whether the control of the lamps is flexible and accurate; whether the switch and the control sequence of the lamps correspond to each other.
