Connecting a lamp with 5 cables and two switches (instructions)

If you want to connect a lamp, this is usually a quickly done job that even a hobby craftsman safely gets there. However, if the living room, dining room or bedroom is equipped with two switches instead of one, connecting the cables can become a small hurdle.

Because what comes how and where, so that in the connection also really everything works smoothly?

With our tips, you can also connect the lamp, for example, if there are two switches.

When five cables stick out of the ceiling

If there are two light switches for one lamp connection in the room, there are usually five cables coming off.
These are typically in the following colors: black, yellow-green, brown, gray and blue. This is normal and correct for changeover switches.

If you want to be on the safe side here, whether they are indeed such switches, it helps to unscrew them once to make sure how many cables are connected per switch. Usually there are three of each.

If this is the case, the following cables are interesting to connect: brown and black, and the yellow-green.

To connect the lamp, it is simply clamped between brown and black, an additional connection is made to the green-yellow as protective conductor.

In the case of protective-insulated lamps (these are the standard), brown is clamped to brown and the blue wire of the lamp to the black cable.

To ensure that nothing goes wrong when connecting, this video offers help with assembly and connection. Any material is shown and explained in detail. In addition one sees here again completely exactly, which cable connections belong together, so that at the end everything functions in such a way, as desired.

Through the instructions in the video you get the necessary insight into the circuit and can then easily and safely connect the new lamp with the switch or. Connect the switches.

What does it look like if a switch is connected, but there are still five cables??

A phenomenon that appears from time to time, even in rented apartments, are power outlets that also seem to be equipped with more cables than are really needed to connect a lamp.

Here, too, the colors black, gray, blue, brown and yellow-green protrude from the wall or ceiling. Here, too, a quick look at the switch itself can be enough to determine which cables are needed for connection.

As a rule, brown, blue and yellow-green are needed here. These are then phase (brown), neutral (blue) and PE (green-yellow). The two remaining cables serve as additional lines, which may be needed for other circuits. Especially with three-phase lamps these come to bear, otherwise these cables can simply be laid to one side with a clamp and do not require any connection or clamping place in the luster terminal.

Here, too, the most important thing at the end:

If a new lamp is to be installed and connected, be sure to remove the fuse beforehand. This is the only way to ensure that no voltage is present during work.
