How do I connect a lamp in my home?

How do you wire a ceiling lamp or chandelier in your home?

Everyone who buys a lamp, must deal with its installation and connection to the electrical system. Contrary to appearances, it is not difficult at all, if we follow a few rules. It is worth before starting the task of connecting lighting to the electrical system to learn the basic safety rules when working with electrical systems. If you do not feel up to it - ask a person who knows about it. Connecting the lamp should not take more than a few dozen minutes.

REMEMBER!
FAILURE TO OBSERVE BASIC SAFETY PRECAUTIONS MAY RESULT IN ELECTRIC SHOCK OR SHORT CIRCUIT IN THE INSTALLATION.

TOOLS NEEDED TO DO THE JOB

Before we start assembling the lamp, we will need some tools:

  • Electric tester (to check if there is current in the installation and to screw the wires in the ankle)
  • Electric cube (usually attached to the lamp itself)
  • Insulation tape (to protect exposed wires)

How do you wire a ceiling lamp on one circuit?

First, let's take care of our safety! Disconnect the power by switching off the main fuse in the distribution box. Make sure that no current is flowing in the wires by placing a tester on the wires. If the light in the tester does not glow - it means that no current is flowing in the system.

There should be three wires protruding from the ceiling or two wires depending on the installation:

  • Black (phase [L] ), blue (neutral [N] ), yellow-green (ground [PE] )
  • Brown (phase [L] ), blue (neutral [N] ), yellow-green (earth [PE] ) 
  • Black (phase [L] ), blue (Neutral [N] )
  • Brown (phase [L] ), blue (neutral [N] )

Often, especially in older apartments, it happens that the wires have different colors or are connected incorrectly. In this case, it is worth checking in which wire the current flows. To do this, turn on the power and check with a tester where the current flows. In the future, you can mark the wire with a piece of insulating tape with the letter [L] written on it, indicating the phase wire.

Now that we know where the current is in the wire, it remains to connect the wires to the electrical block in the lamp. Make sure the current is turned off. Remove about 5mm of insulation from the wire, if the wires were previously skinned, skip this step. Connect the wires according to the markings on the wiring block. Phase wire [L] to the wire marked [L] on the terminal block, and the other wires [N] Neutral (blue) to [N] on the terminal block. PE] wire, if any, connect to the marked [PE] wire on the terminal block, if you don't have it in your installation, leave the block empty (you can insulate it for safety reasons). It is worth to mount the lamp to the ceiling, only that it is not hanging on the wires and check if everything works. If the lamp lights - (NOTE: the lamp lights better when it has light bulbs screwed in - a joke? )  - you can attach the lamp to the ceiling.

How to wire a ceiling lamp on two circuits?

To be able to connect a lamp on two circuits, we have to check if our installation allows it. When there are 3 wires sticking out from the ceiling, brown or black phase wire [L], blue neutral wire [N] and yellow-green protective wire [PE], theoretically there is no possibility to connect the lamp on two circuits. I write theoretically, because in practice there is such a possibility, but it is not compatible with safety rules and I will not focus on it.

However, if there are at least four wires protruding from the ceiling, we certainly have the possibility of connecting lighting on two circuits. In fact, the principle of connection does not differ much from the connection to a single circuit with the small difference that we have at our disposal one more supply cable [L2] phase. The configuration of wires often looks as follows:

  • Black (phase [L1] ), Brown (phase [L2] ), Blue (Neutral [N] ), Yellow-Green (Ground [PE] )
  • Remember! When connecting the lamp - be very careful, improper handling may result in electric shock.

Disconnect the wires according to the markings on the terminal block. The phase wire [L1] to the wire marked [L1] on the terminal block, the wire [L2] also the phase wire to the wire [L2]. Do the same with the other wires [N] Neutral (blue) to [N] on the terminal block. PE] wire, if any, connect to the marked [PE] wire on the terminal block, if you don't have it in your installation - leave the block empty (you can insulate it for safety reasons). It is worth mounting the lamp to the ceiling, just so it is not hanging on the wires, and check if everything works. If the lamp lights - you can mount the lamp to the ceiling.

Installation on two circuits and I want to connect a lamp on one circuit what then?

It happens that we need to connect a lamp to only one circuit, and the installation allows you to connect more. Then we connect the lamp, bypassing one phase wire [L2] (we isolate it before, so it will not cause a short circuit in the installation). All the rest is repeated as in single-phase installation. Connect the phase wire [L] to the wire marked [L] on the terminal block, and do the same with the other wires [N]. PE] wire, if any, connect to the marked [PE] wire on the terminal block. Before you check if the lamp works, it is a good idea to fix it to the ceiling, so that it does not hang on the wires.

What if the installation has one circuit and the lamp is designed for more than one circuit?

When the lamp has the possibility to divide the light into two circuits and the electrical installation does not allow to connect more circuits than one, we can connect the wire [L1] and the wire [L2] together in the lamp. For this purpose, we can use a piece of wire screwed into the cube. See the illustration. By bridging the phase wires in this way we have made a lamp for one circuit, which can be restored at any time.
