My new range came with a 40 amp, 3 wire cord. The breaker for the range is 60 amps.?
Question:Will the breaker trip correctly even though the range is only pulling 40 amps?
Please, no guessers. Thanks in advance.
Answers:
You are fine. The breaker needs to be rated based upon the wire that runs from the breaker panel to the receptacle and the receptacle. The rating, and the cord of the appliance does not matter as long as it is less than the breaker and the carrying capacity of the wire.
If you were to apply the logic that the breaker should not be rated for more than the device pulling the power, you would need to have 1 or 2 amp breakers for your table lamps, a 1/2 amp for your cell phone charger, etc.
Any device that requires specific overload protection must provide that protection within the design of the device.
no
No , check on the brand and pick up a 40 amp / double trip breaker.
as others have said
no
a problem will burn up the range
I would look in your manual, I imagine it will say a 40 amp at a minimum. You breaker will still trip if there is a short. But like the others say if there is a problem with the load it could not trip. On the other hand the wires are larger and rated for the 60 amp so that is not a bad thing. a 40 or 50 will make you feel better just do it. It's not worth you stressing over. But in the meantime use your stove without fear until you get it done.
The range should have it's own internal protection. The breaker is to protect the wiring in the house so it won't catch fire. If the wiring can handle up to 60 amps, then the breaker should be ok. Check where you bought the range, or manual that came with it, to see if it has internal overload protection.
Never put any breaker on exceeds the maximum amp capacity for the wire or receptacles.
Change that breaker right away. If something happens at the stove end a 60 amp breaker WILL NOT trip and may cause a fire. That's like putting a penny under a fuse because it keeps blowing(back in the old days) Breakers are for YOU safety and the safety of your home and family.
If your stove is drawing 40 Amps, then that would mean a breaker needs to allow the 40 amps to pass for this to operate. If that breaker were a 30 amp, for example, you'd never be able to use your stove - it would trip the breaker every time.
If that breaker were a 40 amp, it will allow you to operate the stove " as long as the current never exceded this value" However, at times we experience fluctuations in power, and recieve power surges; furthermore, some devices use more on startup then even out to a set value that they draw. So to have a breaker that is exactly equal to the draw is not a good way to go, it should be higher.
therefore, in your case, you have a 60 amp breaker and if the stove is the only device on that breaker you're in great condition. You see, technically you can operate the stove and about another 10 - 15 amp drawing device(s). But assuming the stove is all that is on tht line you will have no problem of the stove tripping the breaker.
Most people tend to look at it backwards. They think the amperage is forced through to the device, or think in this case the 60 amps is being pumped to the stove and the stove would burn out. this is totally wrong, it is the opposite situation. The stove is drawing the 40 amps through and the breaker must allow this draw, and a little bit more at a minimum. If the stove ever did go faulty it may draw more and short out, this itself will trip the breaker. But as long as that breaker is allowing the operation of the device without tripping the breaker you will be fine.
Remember it this way, the amperage is not pumped to the stove, the stove is sucking the amperage from the breaker. That means 40 amps is being pulled in by the stove.
You're good to go! Your range will never exceed the capacity of your circuit. Conversely, it will never draw more than 40 amps.
