Small panel to feed range and oven

2339 Views 16 Replies 8 Participants Last post by  guest
My customer has a 240V 50A circuit (50A breaker and 8/3 romex) that runs from the breaker panel to the 50A kitchen range. The circuit terminates in an outlet box behind the range. The range is hardwired into this box with an appliance whip. Pretty standard stuff.

He's replacing this 50A unit with a 30A range and a 20A oven (or something to that effect) so he'd like to put a 50A sub-panel under the appliances to avoid tearing up drywall. So the 8/3 romex remains in place and then I'll run flex conduit from the box to the sub-panel and wire the appliances into this panel.

The available space for this panel is only 6" high.

So I need a panel with 4 spaces that is 6" high or less.
The smallest residential panels I can find are 13" high.
Width and depth are not a concern.

Does anyone know of such a panel?

Thanks

You might be allowed to use the tap rule and eliminate the panel and just straight tap both appliances from said circuit. I have only done it twice in 20 years. I believe it is still compliant with some requirements.

Are you referring to 210.19(3) Exception No. 1
Conductors tapped from a 50A branch circuit supplying electric ranges, wall-mounted electric ovens, and counter-mounted electric cooking units shall have an ampacity of not less than 20A....

I believe at one time you could run the 8/3 to a jb and run the flex from the appliances to the jb. As long as the load is appropriate this was allowed but I have not found proof of that. The tap rules don't seem to apply here but I think 210.23(C) does.

Yes, and they are built exactly for this situation. Just explain to the parts guy you need one of these tiny little junction boxes made for it, and he'll know exactly what you need. They're tiny! And it's the way to go! Remember it has to be accessable.
He needs a breaker panel not a j box you ding-dong. :laughing::laughing::rolleyes::rolleyes:

That said, he can use something like a 2/4sp Sqd Homeline with the funky tandem breaker that has two, 2-pole breakers and place it on its side, with the on position to the right. I'll come back with an edit for the cat#s' I'm thinking of...

EDIT 1: Hells bells, I can't find the one I have seen and suggesting. It has two external ties, the two center poles are tied and the two outer poles are tied with a "W" shaped tie (minus the center spike) and looks like two tandems side by each in a single molded case. I'll keep looking.

EDIT 2: Ok, thanks to 220/221 for a recent panel change pic..look at the upper left breaker, with green handles, it is the type I am talking about!:

Peter you're following me around like some queer. Stop it.

I'm looking for a pic. It's for when you have a regular oven, and you're replacing it with an oven/cooktop that's split requiring different power sources.

Could be the USA doesn't have them. Or maybe you guys are just ignorant.
