After drawing up a plan and marking the passage of the wiring on the walls, it's time to think about the configuration, since many points associated with it will be clear. Such as: the number of switches, junction boxes, sockets, the length of the wire, etc. When choosing a complete set, there is one advice - do not buy cheap imported goods, it is better to give preference to domestic products (it will last longer and will work more reliably).
The second point to consider is what type of outlet to buy? There are now two types of sockets in use: the so-called euro sockets (they have a third grounding contact and, most importantly, contact holes of a larger diameter than conventional ones). It is not safe to include conventional plugs in euros. If the contact is poor, sparking or an electric arc can occur, which can lead to damage to expensive equipment, high power consumption and even fire. It is reasonable to equip the wiring with European sockets, since you are not living the last day, and all modern electrical appliances are equipped with plugs of this standard. To avoid problems with old devices, you need to replace unsuitable plugs with euros, or, in extreme cases, you can use an adapter. By the way about adapters, tees,extension cords and other rubbish - they worsen the contact, which leads to network overloads and a significant waste of electricity. Extension cords and adapters should only be used for a short time and should not be left unattended.
Since we are talking about saving, I can give some advice. You can save a lot by simply changing the lighting lamps. If a five-arm chandelier still hangs under the ceiling, this is not rational, because one 100-watt bulb gives one and a half times more light than four 25-watt lamps. New generation lighting lamps are more economical … Where you used a 40-watt lamp, you will need an energy-saving light bulb of only 7 watts, and a 100 watt one will be replaced by a 20-watt one. Thanks to a new type of phosphor, fluorescent lamps shine much brighter, more uniformly and longer. Their service life is calculated for 6 years. Halogen lamps give a luminous flux two and a half times more than conventional ones, and last more than two years.
When buying electrical appliances, pay attention to the labeling. The most economical appliances are supplied with A and B marked with a black arrow in the background. The letters C and D indicate the standard level of economy, and the symbol with the letter E warns of wastefulness.
In conclusion of the article, I bring to your attention several schemes that may be useful. Let's start with the simplest one - this is a circuit for switching on an ordinary three-arm chandelier:
Diode power regulator: To reduce the brightness of the lamp or sconce, you need to reduce the current. A diode connected in series with the lamp will help here. After all, it will pass current only in one half-cycle of the mains voltage, cutting off the second. It is enough to close the diode with a switch - and the brightness of the lamp will be restored. The reverse voltage of the diode must exceed the mains voltage by at least one and a half times, and the permissible current - the maximum load current - by the same amount. It should be borne in mind that at the initial moment, when the lamp filament is still cold, the current jump through it significantly exceeds the one that flows through the red-hot filament. Therefore, you need to choose a diode with an appropriate current margin, or first apply the full mains voltage to the lamp, and then, when the lamp flashes, turn on the diode.
Chandelier control by two wires: The circuit is pretty obvious. As for the diodes, the requirements for them are the same as in the previous circuit.
