If you need a power connection in the garden, you can not avoid installing a ground cable. How to proceed, our step by step guide tells us.He who loves his garden does not only cherish and care for him. Because in order to illuminate the garden nicely in the dark or for the supply of various electrical garden installations and devices power is required. Since in the electrical system the garden is placed on the same level as a wet room, first of all all the components used must be suitable for this application, ie a protection class of IP44 or higher is required. For outdoor installations, it must be IP65 or IP67.
If garden lights, pond pumps or other devices are to be supplied with power over several seasons, it is worthwhile to lay underground cables.
Proper installation - step by step
If you want to supply an atmospheric lighting, a pump or just external sockets with electricity, you must first lay underground cables. These special cables are highly insulated and therefore tolerate moisture, frost and weather. Before you can start relocating, a plan is required. That means, you think in advance, where you need a power connection.
A little hint: The laying of empty pipes saves later Aufbuddeln again.
- Where later the cable is to run along, an approximately 60 cm deep ditch is dug. A previously drawn cord, facilitates this step.
- Then the bottom of the shaft is filled with a 10 cm high sand layer. The underground cable is then laid directly on the sand. This is made more valuable by the use of empty conduits. However, a draw-in spiral is required for retraction.
- Once the underground cable has been laid, another 10 cm thick layer of sand is applied.
- In order to additionally protect the cable harness, covers are used. These are available at the hardware store or electronics retailers.
- On a so-called warning tape should not be waived. This is slightly above the cover. In new earthworks is thus immediately recognizable that there is a ground cable.
- In the last step you fill up again a layer of sand and your underground cable is laid.
Think toowhether a distributor housing or a junction box is needed. An outdoor floor tank can serve here as a distributor housing to allow multiple simultaneous connections. Depending on which devices are to be operated with this, a further floor tank may be necessary for a transformer. Another use of the bottom tank would be the use as a valve box. The outdoor floor tank should be flush with the lawn so that it remains easily accessible through the removable lid.
Alternatives to the wired version
If this procedure is too much work, you can look for battery-operated devices. For example, many garden lights or garden tools are already being operated with solar and battery. The disadvantage here is the frequent replacement of the batteries or the recharging of the batteries. Many luminaires therefore already have their own solar cell, which ensures automatic charging of the installed battery.
