Connecting the ceramic hob - Info & Tips

If you move into a new home, you have to go to the Usually provide for the kitchen furniture and appliances. While the construction of Spülunterschränken, oven cabinets and wall cabinets can be made without problems by the layman, it requires the connection of kitchen appliances such as stove and oven expertise. It looks similar when the kitchen is to be renovated. Frequently, the stove needs to be expertly taken off the grid and replaced if necessary. Those who have not been specially trained to do these activities should keep their hands off the hob and oven.

Technical features of ceramic hobs

Those who buy a ceramic hob are usually given the suffix "self-sufficient". read. This means that a ceramic hob can be installed independently of the oven. If a connection manual is attached to the device, several connection types are described there. Since the devices are now distributed throughout the EU, but the power grid is still not uniform, country-specific conditions must be observed. In Germany, most apartments have a so-called high-voltage connection as standard, to which a maximum of one stove and one hob can be connected. This special wall socket is protected with at least 16 amps and can therefore carry the heavy load from the stove or stove. Basically, a hob can also be operated via a standard safety socket. For protection, however, most manufacturers recommend the connection to the power socket. The same applies to the installation of a stove.

Why a skilled worker is required to connect the ceramic hob

Apart from the refrigerator, freezer and coffee machine, which are simply plugged into the socket for commissioning, kitchen appliances such as

  • need an oven
  • stove (hob-oven combination)
  • ceramic hob
  • induction hob

usually a special circuit. While most appliances work in the household at a voltage of 230 volts, stove and oven are usually dependent on 380 volts. They do not operate with the regular two-phase AC voltage, but draw their energy from a three-phase AC outlet. In colloquial terms, this voltage difference is also referred to as strong, powerful or building electricity. The cables do not go directly into a Schuko plug, but cables must be connected directly in the socket.

By the way, Schuko is an acronym that stands for protective contact.

In general, the cables on the ceramic hob seem to be self-explanatory , The individual cables differ in color and there are also terminals. The corresponding box in the wall is provided with a cover, under which in turn are terminals for connection, which are each marked. Accordingly, the cables are connected to the appropriate terminals:

  • Brown to Brown
  • Black to Black
  • Blue to Blue
  • Yellow-Green to Yellow-Green

However, it becomes problematic if the marks are different from each other and the cables have different colors. Normally, the terminals on the box are labeled L1, L2, L3, N and earth or PE, but labeling with 1, 2, 3, 4 and earth or PE is also possible. In addition, the cables do not always have to be executed in the stated colors. Only the grounding is always striped yellow-green. L and N lines do not always have to be brown, black or blue. The risk of misallocation of the individual cables is correspondingly large. In addition, the terminal number of the box may not match the terminal number of the unit. Then so-called bridges must be switched. This activity is reserved for trained professionals.

As always, when handling electricity, the utmost care must be taken. Before cables are connected, be it from the ceramic hob or from the new room light, the appropriate fuse must be switched off. Otherwise it can lead to life-threatening electric shock. However, the individual circuit breakers can not always be assigned exactly. If the wrong fuse is applied, electricity will continue to flow and there will be danger to life and limb.

Even if the layman tries to connect the ceramic hob by himself because he thinks he can correctly assign the cables and terminals If the fuse is switched correctly, self-assembly of the ceramic hob can be a problem.

Failure to connect may result in fatal consequences for the appliance. A short circuit can permanently damage the ceramic field and render it unusable. If the line goes over the case, in the worst case, there is power on the device. Contact may cause electric shock again. In addition, most of the manufacturer's warranty agreements include the clause that any warranty claim is lost unless the cooker is installed properly.

So, in order to claim warranty damage from the manufacturer, the bill should always be removed by the fitter the expert before

So that the expert does not even get the opportunity to guess colors or markings, he uses a measuring device. With the professional tester, the electrician can determine exactly which conductor is the neutral and how the individual phases are numbered. Depending on the age of the can vary, as I said, the markings considerably. Years ago and decades, other legal standards have applied. Without the corresponding meter, the connection becomes a guessing game. If the socket for the high-voltage connection is missing in the first place, specialist personnel must be consulted in any case in order to install the suitable box first.

Costs for installation

The connection of the ceramic hob by a specialist is considerably safer and maintains full warranty. If the ceramic hob was purchased from specialist retailers, the specialist staff can cost-effectively carry out the installation. The investment is worthwhile. After all, a wrong connection can not only damage the ceramic hob itself - and this without warranty claim - there is also a further legal risk for the self-connection: If the fire breaks in the apartment later, the insurance can demand proof of professional installation. For this reason as well, the installer's invoice must be canceled.

Summary

Connecting a ceramic hob requires expertise. Only if the hob is connected by qualified personnel, is there full warranty. In the event of an insured event, it may also be necessary to prove the expert installation. Therefore, the bill of the installer should always be stored safely.
