You may use it but it's not safe to do so. The reason is,if a fault occurs in the dryer such that the current being drawn by the dryer increase but it's still lower than 40Amps,the current will heat the insulators of the electrical cord which will gradually destroy the insulator and in extreme case,it might burn the insulator causing fire.

Can you use a 40 amp range cord on a dryer using a 30 amp breaker?
Yes you can if the dryer uses 30 amps or less. A cord can always be bigger than needed, it can take 30 amps just as easily as its upper limit of 40 amps. If you were starting out you would buy a 30 amp cord because a 40 amp one would cost more.
Can you hook up a two pole 20 amp breaker to a 30 amp outlet for a dryer?
Probably not. If the appliance has multiple heating levels then you might get away with it. In this scenario you would only be able to use 30 amps of the appliance's 40 amp capacity before the breaker would trip.
Can an electric range be powered from the same circuit as an electric dyer?
No. The two appliances usually have dedicated circuits. The range will have a two pole 40 amp breaker and be fed with a 3-C #8 copper cable. The dryer will have a 30 amp two pole breaker and be fed with a 3-C # 10 copper cable. As you can see by powering a 40 amp device from a 30 amp breaker, full operation of the range will trip the 30 amp breaker.
Is a 40 amp circuit breaker ok for a 30 amp air conditioner?
Yes. You should use 8 AWG wire from breaker to AC unit.
Can a 40 amp breaker not a 4 amp breaker be used to replace a 35 amp breaker for ac unit?
Depends on the size of the wire going to the A/C. If the wire is AWG #10 you cannot install a 40 amp breaker. If the wire is AWG #8 you can.

Can you use a 60 amp breaker for a electric stove?
If this is the main service in your home then you probably could not run both appliances at the same time. A range has a 40 amp breaker and a dryer has a 30 amp breaker protecting the feeders to these appliances. Even though both appliances do not draw the maximum current that the breaker allows it would be close. With other devices in use through out the home with the range and dryer on at the same time it will probably trip the panels 60 amp breaker.
Can you hook up a two pole 20 amp breaker to a 30 amp outlet for a dryer?
Probably not. If the appliance has multiple heating levels then you might get away with it. In this scenario you would only be able to use 30 amps of the appliance's 40 amp capacity before the breaker would trip.
What are the standard size circuit breaker amperages?
In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.

Will your spa work with a 40 amp breaker even if it says 50 amp on the plate?
No, because if you switch a 50-amp load on, it will blow a 40-amp circuit breaker if the load exceeds 40 amps, which is likely.
What type of appliance would be use a two pole 50 amp breaker?
In North America this size breaker could be used on a welding machine. A range in the home would use a 40 amp two pole breaker.
Can you replace your current cooker fuse 30 amp with a 40 amp circuit breaker?
A 30 amp breaker is designed to trip at an earlier point than a larger 40 amp breaker so one appliance that operates on lower amperage level could be unsafe or damaged before it could trip the higher 40 amp breaker. Also, the existing wiring may not be rated for 40 amp service.
What is the difference between a 30 amp and a 40 amp breaker?
10 amps
Can you upgrade a 15 Amps circuit breaker for a 40 Amp for a 8.5 Watt shower?
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
