Tapping in kitchen

[Praedatus1]

So lets say i have a range that draws 42 amps, is there a provision in the NEC that allows me to run a 6-3 romex, tap it to get 120v, and feed a warming tray that draws 6.5 amps 120v? i have the 4-wire feeding the range and I upsize the breaker to 60a 2-pole. This is hypothetical, of course, I would never normally do this, but I have a contractor that is changing a kitchen that sits on a cement pad, so no access, but the range has a newer 6/3 with ground romex feeding already, so hence my question to get power to warming tray next to the range. Thanks in advance, you guys always have the best answers!

Take a look at 2005 NEC 210.19 (3) Exception 1 and 2 on taps for household ranges.

so am i to take this code reference to imply I CAN perform the tap, even though the range is 240v and the warming tray is 120v, the load imbalance is acceptable as long as
I meet the overcurrent protection requirements, i.e. upsizing to the 60a breaker? I am, of course, going to flex in the warming drawer with #12 wire.

The exception limits these taps to be performed up to a 50 amp branch circuit. 60 amp OCPD no good here.

210.19 (A)(3) exception 1

aaaah sorry i was looking beyond the answer on that one. Right, 50 amp max. I guess my main question here was the tapping on one leg and not the other, you know, 120v from 240 feeder. so say a 23 amp 240v cooktop and a 6 amp 120v warming drawer.

What's the plan to protect the #12 wire.

 

[Praedatus1]

well that may be the ultimate issue, I'm not setting a fuse on it, so I guess the code doesnt cover these parameters because it's simply not allowed, it just doesnt have a specific code preventing it. there would be a lot of boundaries here if it were i allowed i think, so Im gonna tell the contractor that we have to find another way.

I bet the manufacturers instructions require an individual 15 or 20 amp circuit.

My take is this....

If there is a remodel being done and the people want certain things then they have to be willing to do what it takes to get these things. Such as making holes where needed to run new circuits for the appliances they desire.

Take the 60 amp feed and istall a small panel. Feed the range with a 40 amp circuit and whatever else from the new panel.

One more thing... Do you know what hypothetical means.....:wink:

Can you use that 6/3 wg and add a sub panel somewhere???
