The laying of wires for garden lights is related to the safety and stability of their use. Strict specifications and safety points must be followed.
First of all, in terms of wire selection, it should be determined comprehensively based on factors such as the power, quantity, and laying environment of the garden light. Generally, wires with good insulation performance and strong weather resistance should be selected, such as cross-linked polyethylene insulated wires. For garden lights with higher power, it is necessary to ensure that the current carrying capacity of the wires is sufficient to avoid safety accidents caused by overloading and heating of the wires. For example, if there are multiple high-power decorative garden lights in the courtyard, it is necessary to calculate the total power and select wires of appropriate specifications.
Secondly, the planning of the laying path of wires is crucial. Areas prone to water accumulation and external damage should be avoided as much as possible. If it is necessary to cross the lawn or flower bed, protective measures should be taken, such as putting on a hard protective tube to prevent it from being dug or damaged during daily maintenance or other activities. At the same time, a safe distance should be maintained from other underground facilities to avoid mutual interference or damage during construction.
Furthermore, the connection of the wires must be firm and reliable. Use professional wire connection accessories, such as terminal blocks or welding, and do a good job of insulation. Simple winding connection is prohibited, because this connection method is easy to loosen during long-term use, resulting in poor contact and sparks, causing fire or electric shock hazards. After the connection is completed, use insulating tape or heat shrink tubing to wrap the interface in multiple layers to ensure good insulation performance.
In addition, grounding protection is an indispensable safety measure. The metal casing and related metal parts of the garden light should be reliably grounded, and the grounding resistance must meet the requirements of relevant standards. The grounding system can use an independent grounding electrode or be connected to the building's main grounding grid. When a leakage fault occurs in the garden light, grounding can quickly conduct the current into the earth to ensure the safety of personnel.
Then, during the laying of wires, a reasonable inspection well or junction box should be set up. It is convenient for future maintenance, inspection and troubleshooting of wires. The inspection well should have waterproof and moisture-proof functions, and the location should be obvious and easy to find, and the internal space should be large enough for easy operation.
Finally, after the laying of the wires, strict insulation testing and power-on testing must be carried out. Use a professional insulation resistance meter to measure the insulation resistance of the wire to ensure that its value is within the specified range. The power-on test can check whether the circuit is unobstructed and whether the lamp is working properly. Only after the test is passed can the garden light be officially put into use to provide safe and reliable lighting for the garden.
