The connection from the ceramic hob

The ceramic hob has long been standard in modern kitchens. This now also the often slightly different connection compared to a conventional stove is required. All special features and aspects to consider when connecting a ceramic hob we have summarized in detail below for you.

What is a ceramic hob actually?

First of all, a distinction must be made between the colloquial and the technical meaning of the term "Ceranfeld". A ceramic hob is the glass ceramic hob of the Frankfurt manufacturer Schott AG. He was instrumental in the development of this technology using halogen or infrared in the 1970s. The term "Ceran" was already protected in the 1960s. Ceran was then used in space technology.

Ceran is a protected brand glass ceramic

Thus, strictly speaking, every ceramic hob is a glass-ceramic hob, but only those from Schott are actually a ceramic hob. However, the term has established itself through clever consumer marketing and is associated with a halogen cooktop (red and hot). In fact, the term can also be used for all other forms of a glass-ceramic cooktop:

  • Ceramic hob with halogen / infrared cooktops
  • Glass ceramic hob with induction hobs
  • Glass ceramic with gas (gas on glass, gas under glass)

Self-sufficient and combination appliances (hob and oven)

The connection of the induction hob and the ceramic hob (in the sense of the halogen hob) is identical. This also applies to the special features that make up both hobs:

  • Use as combi appliance with oven, connection to the oven, a common Herddosenanschluss
  • Use as a self-sufficient cooking hob, direct connection to the herd box, independent of the oven

Connection of self-sufficient ceramic fields

This results in the problem, if you want to install a ceramic hob, that you are dealing with a special connection way. The new ceramic fields distributed in Germany are available in the same packaging throughout Europe. However, the electricity grids are different. Not every country, as in Germany, has a 400 V three-phase network, which is available to private households.

Therefore, usually different connection options are given:

  • 230 V AC voltage
  • 400 V three-phase current
  • 230 to 240V or 130V

Even the connection to 230 V AC does not really refer to Germany - at least not if the ceramic hob has more than two cooktops. Do not let that irritate you by the fact that the new ceramic fields are usually prepared for 230 V connection by bridging the two outer phases.

Connection from the ceramic field in Germany

This bridge should be removed. The connection should be made to the 400 V mains, if available. The port looks like this:

Three-phase socket

  • Outer conductor L1
  • Outer conductor L2
  • Outer conductor L3
  • Neutral N
  • Protective conductor PE

The oven and hob are connected as follows:

ceramic hob

  • first outside phase on L1
  • second phase on L2 or L3
  • Neutral on N
  • Protective conductor on PE


  • L (on the oven) on L2 or L3 (whichever was not used for the ceramic hob)
  • Neutral on N
  • Protective conductor on PE

Both devices share protective earth and neutral. A professional installation provides that in this constellation, a Schuko box is installed next to the stove junction box. Then the corresponding wires from the three-phase socket are placed on the Schuko socket. Pay attention to the minimum requirements for the cable cross-section.

Schukodose is not the same as Schukodose!

Under no circumstances may you use any Schukodose anywhere in the household and maybe even more or less professional extend. Conventional Schuko outlets are designed for a continuous load of 10A. However, 16A should always be present for a short time. The outer conductors of the three-phase connection are protected in private households, however, usually with 16A, so also sufficient.

Electrical connection only by a specialist

Under no circumstances should you make the electrical connection from the ceramic hob if you are not really familiar with electricity. Of course, when retrofitting a ceramic hob, you can install the hob. But leave the electrical installation to a specialist.

Tips & Tricks

If you connect your own Cerankochfeld and it comes later to a flat fire, of course, the insurance is called. The insurance company for a ceramic tile certainly wants proof that the connection has been made by a specialist (official) - and will hold it accountable if necessary. This not only poses a danger to the amateur installation, but also a tremendous risk of shipwrecking economically in the case of the case.
