Two ovens on one circuit – electrician installed only one circuit

Again, hello,

after Machsselbst's comment, I quickly googled: It indeed seems that for new installations every device over 2 kW must be individually protected.

You should still verify that. But if that is true, any further discussion is unnecessary.

Lay additional wiring, "whatever it takes."

Otherwise, you'll be in deep trouble if there's ever any problem with the wiring. (Unrealistic) worst case: first your oven burns down and then the house, and the insurance does not pay because the electrical installation was not VDE compliant.

You just must never use both at the same time. The electrician should be able to make that controllable with one switch.

You are definitely overloading your circuit with this, because even the refrigerator with its 200 to 300 watts is too much when the oven with rapid heating requires its full 3.6 kW.

The (one) oven has a power rating of 3.3 kW. Therefore, you are not overloading it (especially if it is a new refrigerator with 0.1–0.2 kW). Compliance with VDE & co. is another matter (yes, you are right about that, but the OP needs a pragmatic solution that works—and as long as the oven is not running pyrolysis at the same time the compressor needs its starting current, this is pragmatic).

Another idea: Can't a socket circuit be "misused"? That is, put the refrigerator on one circuit and operate the second oven on the refrigerator's circuit? That fits all the rules. But here (as well as otherwise when the refrigerator is run with other devices) of course a short circuit in the socket circuit caused by another device can lead to the refrigerator having no power for a whole day.

You just must never use both at the same time. The electrician should be able to make that controllable with a switch.

That is practical nonsense. How often are both ovens on for me? Whether the microwave function is used in parallel or warming plates/food until the rest is ready. Or different menu parts are in the oven at the same time.

Hi,

Um... is the irony tag missing here?

You just must never use both at the same time. The electrician should be able to make that controllable with one switch.

You install two ovens in the kitchen because you use them simultaneously... Not one on Mondays and the other only on Tuesdays...

So it's definitely doable after all, or am I seeing it wrong?

Yep. I wouldn't even discuss it further - not such a big effort. At most a "I don't feel like doing that".

That depends on the kitchen. In my case, the cabinets stand on stilts with a toe kick facing the room that can simply be removed. Then it's easy.

Otherwise, it could be harder if the cabinets are closed at the back/bottom and you therefore can't reach the cable.

In that case, I would recommend taking the oven out on the left, which has to be done anyway. The cabinet is probably not closed at the back to allow air circulation. In that case, you can try using a pulling aid to get through the opening and then somehow connect it from underneath. Once you have something to pull through, it should be okay.

Maybe don't use NYM but a cable for outdoors (NYY?) – if it lies on the floor behind the cabinet, something might run under it. Ideally, there would be a flexible protective conduit around it.

In an "emergency," you can also lay the cable inside the cabinet, drilling through the wood each time. It won't be visible behind the drawer and the dishwasher. Then you are directly under the sink without any effort.
