Portable short-circuit grounding wire Usage:
1. Before using the portable short-circuit grounding wire, check the power before confirming that the power has been cut off and confirming that there is no voltage on the equipment. Connect the grounding clamp to the grounding net or flat iron first, and then use the grounding operating rod to tighten the wire end to the device wire. When removing a shorted ground wire, the sequence is exactly the opposite of the above.
2. The short-circuit grounding wire installed, and the distance between it and the live equipment, taking into account the influence of the ground pendulum, the safety distance should not be less than the value specified in the new "Regulations on power safety work".
3. It is forbidden to use the winding method to make a short circuit to ground without using clamps.
4. If there is a grounding point at the suspension point, use a grounding clamp or dedicated copper rod for grounding connection. If no fixed grounding point is available, use a temporary grounding point. The depth of the grounding electrode buried in the ground should not be less than 0.6m.
5. The portable short-circuit ground wire should be properly stored. Before each use, they should be carefully inspected for completeness. The soft copper wire is not exposed and the nuts are not loose. Otherwise, they must not be used.
6. The test period of the portable short-circuit grounding line is once every five years, and the inspection item is the same as the factory inspection. The test qualified portable short-circuit ground wire after being subjected to a short circuit, should be subjected to the short circuit current according to the size and appearance inspection judgment, and should be generally portable short-circuit ground wire <br> <br> using scrap handling:
(1) When connecting the grounding wire: Connect the grounding clamp first and then connect the clamp; when removing the grounding wire, you must disconnect the clamp first according to the procedure and then remove the grounding clamp.
(2) Installation: Connect the grounding wire to the eyelet of the copper nose on the ground rod and fix it on the grounding rod (fixed and movable). It is fixed on the ground clamp or ground pin to form a complete set of grounding wire.
(3) Verify that the voltage level of the grounding rod is the same as the voltage level of the operating equipment.
(4) Make sure that the device or circuit is used after the power is turned off.
(5) Operation process The operator should wear related protective equipment, such as insulating boots, insulating gloves and safety helmets, and use it under special supervision.
Rhein Lighting has developed a line of super slim Led Downlight with a junction box. This panel led downlight is IC rated, which is permitted to be in contact with insulations in ceilings.
The led down light use the new generation of LED chips with higher lumen ouput and lower power, saving you up to 88% in energy costs.
The ultra-thin smart downlights is only 0.47 inches and requires as small as 2 inches ceiling spaces, fits various ceilings, and around joists. 5%-100% smooth dimming meets kinds of needs in applications such as kitchen, living room, bedroom, bathroom and common areas in your home or office.
Rhein Lighting is a professional manuafacturer of slim LED downlight, LED panel down light, Led Panel Light, Led Strip Light, LED rope light, LED plant light and Led Grow Light etc.
