We're planning for a kitchen remodel.
Right now we have an electric range (gas is not available on our street) with a 220v line.

My wife wants a double wall oven, which will mean a separate electric cooktop. Will we need to run another 220v line?

There's no room in the electrical panel, so I'm hoping that isn't the case, or it's going to get more expensive.

The Viking specifications for their double wall oven state only they need 50 amps current capacity. I have no idea what I'm talking about officially, but your question sparked a bit of research as I am also planning a kitchen remodel. 50 amps is a bunch of amps, and I have doubts that the existing oven wiring can handle that.

Do you have a full 200A panel? If you only have 100A, you're probably in for an upgrade anyway.

You’ll need to verify the electrical requirements of the particular unit you want to buy but if it is 50 amp than it will require another 220 line.

Depending on your panels manufacturer they make split breakers to allow you to get more circuits into them but you’ll want to verify that it will not overload your panel.

Agreed. I would not want to add another 50 amp circuit to a 100 amp panel but that’s just me.

I think it's a 200 amp panel.

When I had a mini-split system installed a few years ago they ran a 50 or 100 amp feed and put another panel on that side of the house.
They could always run off that panel.

I'm going to have to check both of them.

It sounding like it's going to require another line, but as was said we need to decide on the units and check their specs.

Depending on the panel and breakers you have you may be able to put in some piggy backbreakers. This is where two breakers are built into the normal size of one breaker.

As always check all local codes.

You’ll definitely need another 220 feed. If there aren’t any free breaker spaces in your panel you can use tandem (aka piggyback) breakers on a couple of circuits to free up a couple of spots for the new line.

This is the kind you’d need if you have a Square D Homeline brand panel. Just use the same amperage rating as the old. This is a 20 amp obviously. https://www.homedepot.com/p/Sq...HOMT2020CP/202353308

An electrician will be doing the work, so I expect it will be done correctly.
I'm trying to estimate expense at this time.

I checked, and the subpanel is 100 amp. That panel has free slots, so I guess we'll have to run from there. It's a little farther from the kitchen, but only about ten feet more.

Thanks for all the feedback.

The local code may prohibit them, but it is more likely the panel itself might not support them. Before any of that, the real issue with a 50 amp rated one would be heat. They aren't unsafe when installed correctly, but they can't cope with the heat like the full size breakers. So they won't last as long. For 15 amps, eh fine. 30 and up and my electricians won't use them.

Cook tops and wall ovens require 30-50a circuits for each unit, wall ovens are usually 40a. Either way I would run 50a to both circuits. I would not use the sub, unless it has very little existing load.

No one here is recommending using tandem breakers for your oven or cooktop feeds. I only use them for 20A circuits or less. Use full-sized breakers only above 20 amps.
