Connecting electrical appliances & IKEA gas cooktop, assistance with connection.

Hello everyone,

I have now almost completely assembled an Ikea kitchen and am now facing the question of what I need to consider when connecting the electrical appliances and the gas cooktop.

Specifically, I have the following questions:
- Is it allowed for the gas line of the cooktop and the electrical cables of the cooktop and electric oven to lie directly next to each other? (I have to lead them through an opening between the cabinets.) Alternatively, I could drill a second hole between the cabinets.
- Am I allowed to connect the gas cooktop myself at all, or is that not permitted? (e.g., for insurance reasons)
- Is it allowed to plug the dishwasher into an outlet under the sink, or should that be avoided?
- Can I connect any devices to the high-voltage connection? It should have 3 phases. Is there any objection to connecting the cooktop, the electric oven, and a retractable power strip here?

Thanks in advance for the answers! As you can see from the questions, this is the first kitchen I am putting together myself =)

Hello,
the gas connection should be done by a gas installer. Less for the sake of the insurance but as protection for your own life and that of others in the house. You may only connect the hob yourself if a gas socket is present and the hob is already supplied with a mounted connection hose for the gas socket as well as a Schuko plug.
Basically, the appliance connection can be divided into three electrical circuits. This is work for an electrician who knows which regulations must be observed.
The dishwasher can be connected to the socket in the sink cabinet. If the electrician is already in the house, he can take a look at it and consider the special conditions on site.
