OT 240V outlet

My wife wants to replace an electric range (240V) in the kitchen with a cooktop and a new double oven. This means I'll need another 240V outlet in the kitchen. Does this mean I'll need another circuit run from the fuse box, or can I just take it from the existing outlet?
Thanks

Depends how many amp breaker is the existing plug on?

Probably. Your dual oven will probably draw 6000 watts (3k each top and bottom) so on 240 that will be about 25 amps. Your cooktop could draw up to 7400 watts or 31 amps. So you're at 56 amps with everything running. Probably more than the standard range outlet you have. Most are 40 amp and I've seen several 30 amp connections.

If you hook them all to the same circuit you can run one or maybe two at a time but not everything. This is risky because you don't want a breaker tripping in the middle of your wife's holiday meal fixin. Run the second circuit, maybe upbrade teh exisitng one at the same time so you know you're safe.

My electric oven has a dedicated 60amp breaker, 240vac. If both of the ovens you have total less then the breaker ampacity then you should be okay.....If I was you wait until Buick and Deere chimes in with his answer.

Okay, heres the deal:

1) Can you use an existing outlet??????

The answer is MAYBE but I wouldnt bet too much since the new set up may require more amps then the old stove PLUS it may require 120/240 (4 wire) instead of straight 240 (3 wire) as many older stoves were set up!!!!!!!!!!!! In the old days they only ran 3 wires (2 hots 1 ground) to stoves, but nowadays many require 120 and 240 so they run 4 wires (2 hots, 1 Neutral, 1 Ground) PLUS the new set up may require more current then the old ALL MUST BE CORRECT amperage and type and poles of receptacle

QUESTIONS FOR YOU: What TYPE (amps, poles) Receptacle does the old stove have and what is on the new set up??????????????????????? If they are the same (amps and poles) you can likely use whats there BUTTTTTTTTT if the new set up requires a higher amp service and/or different receptacle (poles OR amps) then you need to upgrade


a) For a stove branch circuit you will need:

1)The correct ampacity i.e. the correct sized circuit breaker in the panel,,,,,,

2) The correct size and number (3 or 4) feed wires from the panel to the receptacle,,,,,,,,

3) The correct size receptacle (i.e. 40 or 50 or 60 amps etc)

4) The correct receptacle like a 3 pole or a 4 pole (plus correct amp rating). Old stoves often used a 3 pole, 2 hots and a ground, new stoves may use 120/240 so they requires 4 pole receptacles, 2 hots, Neutral, Ground

SOOOOOOOO once you know the new set ups amps,,,,,,,,,the receptacle (poles and amps) it uses,,,,,,,,,whats there now (poles and amps)

THE ANSWER CAN BE DETERMINED

If I missed anything hopefully the gents with more current experience can add to this as Im a long retired as an electrical distribution engineer and rustyyyyyyyy as an old nail lol

And to add, most older ranges were 3 prong plug; today's ranges really should have 4 prong.

I'd be surprised if you were good to go, but like John T says, what size breaker do you have, and how many amps do the new parts all draw together?

Look up the installation guides for the units you intend to buy on the manufacturer's web site. That will tell you the power requirements for each unit. If the total amps required by the two units is no more than what you already have, you could get away with it.

Personally I would never run two 240 volt appliances off the same circuit, unless it was totally impractical to run a new circuit. I suspect that's code as well.

Doug, your existing outlet is most likely not approved for the extra wiring. All I can think of now. John T. covered everything else.
