The garden, the terrace, or a courtyard need electricity to supply, for example, lighting or sockets. The outdoor circuit is an integral component of the electrical installation for a home. Is it mandatory to bury the cables? What are the steps to follow? You should book electrician service in Jail Road Lahore to avoid electrical hazards in your home. Or follow our advice for a successful outdoor electrical installation.
The Importance of the Differential Circuit Breaker
To distribute the current to the various points of use (lighting, sockets, annex building, etc.), an R2V cable of sufficient cross-section must be used.This security makes it possible to isolate the external circuit from that of the house and to cut off the current in the event of an incident (short circuit, insulation fault, etc.).
All the exterior circuits must be independent of each other (one circuit for the garden lights, another for the exterior sockets, a third if you have an electric gate, etc.).
Watertight Equipment
Electrical equipment installed outdoors must all be earthed and waterproof. The IP rating gives the waterproofness of an electrical appliance: to be installed outdoors. The IP must be at least 24. Electricity professionals advise to go for IP44 or even 65 or 68 for sprinklers or swimming pool equipment.
Outdoor sockets must also be installed at least 1 m from the ground.
The NF C 15-100 standard requires the installation of a lighting point at least above each entrance to the house and annex buildings. You can fit these with either a conventional switch or a motion detector. If the point is not yet connected (for example, a missing luminaire on the terrace), the electrical supply must not remain bare but make sure you equip it with a connection box, possibly fitted with a base.
Sounds tricky right? Don’t worry! You can book electrician work in Jail Road Lahore and get the job done by a professional in a stress-free way.
Visible or Buried Installation?
A buried electrical circuit guarantees better security, which is why it is wise to anticipate it from the construction of the house if possible. However, in the case of a renovation or for a simple installation (patio lighting), a visible installation can be considered. You can book electrician in Jail Road Lahore through an online app like Mr. Mahir app for visible installation.
Buried Installation: The Most Recommended
Here again, standards specify the rules that you should follow:
- You must bury the cable at a minimum depth of 50 cm for a garden and 85 cm for an alley (to avoid the phenomenon of crushing).
- Also read, a warning screen must be placed 20 cm above the sheath (this allows, during subsequent work, to know that an electric cable is passing at this location).
The Apparent Pose
This is possible by using specific conduits called IRL (smooth rigid insulation), which can also be used indoors. However, we recommend you this type of installation if the electrical circuit is very exposed to humidity. You should reserve it for powering the lights on a terrace, for example.
1. Make a Circuit Map
On the ground plan of your plot, position the electrical panel (lighting, sockets, gate, automatic watering system, etc.). Then connect them with lines representing the cables, not forgetting to make a circuit by type of device.
Straight lines and shorter journeys are ideal, but you can also follow the design of a lawn or a driveway.
2. Bury the Cables
After digging your trenches respecting the standard depths indicated above, you spread a layer of sand of about 10 cm in the bottom. On top lay the sheath containing the cable, then a second 20 cm layer of sand. Finally, you extend the flexible warning mesh over the entire length of the trenches you close with the soil you have removed.
3. Connect Your Devices
Follow the instructions for connecting your electrical devices, ensuring that the connection is watertight. If you think doing all this is too risky and you do not have the required skills, book best electrician in Lahore.
