How to connect an LED chandelier with three wires
Connecting lighting fixtures may seem like an easy task. You may be thinking that it can be difficult to connect the two wires that come from the ceiling? But in certain cases, an ordinary man who has taken up household chores may face an unexpected problem - what to do if there are 3 wires coming from the ceiling, how to connect a chandelier?
We suggest you figure it out question.
To properly connect the chandelier, you will need the following:
- Insulating tape.
- Terminal block for 3 terminals.
- Indicator type screwdriver or voltage gauge.
Also, you will definitely need a stepladder or even a stable stand, a sheet of paper, a marker and a passport of the lighting device.
The simplest option would be to use a specialized electrical circuit that you can find in the passport for the lighting device.
There, as a rule, indicate the purpose of all types of cables and step-by-step connection instructions. For normal standards, cable color marking should be done like this:
If there is no documentation for the chandelier, and the color coding of the wires will not indicate unambiguously their belonging, it is required to determine their purpose using a multimeter.
Put the first probe from the multimeter on the side-type contact on any of the cartridges, and the second one in turn should touch the stripped wires that come out of the chandelier. When you touch one of several wires, you will hear a sound signal - this wire, and there is also a zero. It must be marked with a marker or any other method.
Find the phase wire. To do this, you need to put the multimeter probe on the middle contact of each of the cartridges, and next touch the two wires that remain.
By means of a sound signal, it is required to determine the phase wire, mark it or just remember it.
The signal will be able to confirm that the chandelier is of a double-circuit type, and the second wire is also phase.
Let's consider how to connect a double-circuit chandelier to the network.
How to connect a chandelier with 3 wires? To do everything right, and two of the three are phase, you need to inspect the switch and the wires coming out of the ceiling. The simplest option is when the switch is a two-button type, and only 3 cables come out of the ceiling. You can find out the purpose like this:
When in contact with the phase wires, the lamp on the voltage indicator will light up.
Turn off the breaker. It is required to check all three wires again, and the lamp should never light up.
It is required to connect everything by means of a terminal block or twisted using insulating caps or even insulating tape.
If the switch is of one-key type and only a couple of wires will come out of the ceiling, then you need to check them with the switch connected with a voltage indicator and find the neutral and phase wires. The latter are required to be connected to each other and to the phase wire of the electrical wiring, and the zero ones are also connected. Check enable and disable.
If the switch is one-key, and there are three wires in the electrical wiring, you need to find out the purpose of the third wire. To do this, turn on the switch and check the presence of voltage on all wires. If the phase is detected on two wires, and the chandelier can be connected in a three-wire pattern. If the phase is only on one wire, and the third wire is yellow-green, then the connection is made as in the last case - connect both wires of the chandelier phases to the phase wire of the electrical wiring, and the grounding type conductor must be insulated and removed.
If the lighting fixture has a metal case, it must be grounded.
In new apartments, all electrical networks, including lighting, according to standards, must be with a yellow-green grounding conductor. If your electrical network meets this requirement, then to connect the chandelier it will be enough to connect the wires with the corresponding color markings using an adhesive block or even twisting.
If the network is old, and the insulation of all wires has the same color, then it is important to proceed in the following sequence:
Now let's look at safety precautions.
Care should be taken when connecting any electrical appliances. All connections and connections are required to be carried out only with the switch off after checking the absence of voltage on the wires.
The places where there will be twists must be insulated with insulating tape or special caps. If you doubt that you can connect a chandelier with three wires, that's right, you should entrust such a thing to professionals in their field.
