# Can you use a 30 amp breaker for a refrigerator?

Not unless the wire going to the refrigerator outlet is AWG 10/2. If it is wired with 12/2 wire then you must use a 20 amp breaker. Using a 30 amp breaker is dangerous and a fire hazard.

### Can you use a 20 amp circuit breaker for an electric dryer?

If you are referring to a cloths dryer, the answer depends on the requirements of the dryer. Most dryers require AWG#10 wire with a 30 amp fuse. If the wiring is AWG#12 then use a 20 amp breaker but never use it on AWG#10 which requires a 30 amp breaker. If you are referring to a hair dryer then yes a 20 amp breaker is fine.

### What size wire for 75 feet of wire for a 30 amp 220 volt oven?

A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire…

### Should 25 amps breaker be replaced by 20 amps?

Depends on what size wire was used in that circuit. AWG #10 wire requires the use of a 30 amp breaker AWG #12 wire requires the use of a 20 amp breaker AWG #14 wire requires the use of a 15 amp breaker Check the wire size in the circuit and you will know what size breaker to use. It is not going to be a 25 amp breaker.

### How big of breaker do you use for 115 volt?

Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.

### Can you use a 30 amp breaker when you have need for only 20 amps?

The question is one of protection of conductors (wires). A 30 amp breaker must have a #10 copper conductor or larger for adequate protection. A smaller wire (larger number) such as #12, is not protected by a 30 amp breaker. If the equipment you are powering only requires 20 amps, using a 30 amp breaker and #10 AWG wire is acceptable provided all other elements of the circuit are listed for 30 amp circuits.

### Can you use a 30 amp breaker for a stove?

The breaker commonly used for ranges is a 40 amp. This size is used to cover the total wattage of the range. If for some reason all of the top elements and the oven were in use at the same time then the amperage drawn would be just under the trip setting of the breaker. If this same scenario were played out on the range with a 30 amp breaker supplying the power it would…

### What size of a circuit breaker is needed for a 30 amp circuit?

A 30 amp circuit breaker is needed unless the load is a motor circuit, then it has to be sized to 250 percent of the motors full load amps. For 30A circuit is needed breaker 30*1.25=37.5 --> 40A. If load is lamp or heater, then use breaker of group A or B. If load is motor, then use breaker of groupC or D (very hard start) or special safe breaker for motor - with variable…

### Can you use 12-2 with ground to wire a 2000 watt forced air heater to a 240 volt 30 amp breaker?

No. The ampacity of a #12 wire is 20 amps. Being connected to a 30 amp breaker means that the wire can be overloaded by 10 amps and still not trip. There are two things that can be done to stay within the electrical code. Number one, change the two pole 30 amp breaker to a two pole 20 amp breaker. The load of the heater is I = W/E, 2000/240 = 8.3 amps. That…

### Is there a adapter for a nema 14-30 plug and a nema 14-50 receptacle?

No there are no adapters made for these types of installations. The reason there are no adapters is to provide a factor of safety. To plug a 30 amp plug into a 50 amp receptacle could allow 50 amps to be applied to a 30 amp rated cord. The 50 amp receptacle is more than likely being fed by a 40 amp breaker. Just change the plug cord to match the ampacity of the breaker…

### Can you use a 50 amp breaker connected to a 30 amp receptacle?

No. The the 30 amp rating on the receptacle is the rating that the manufacturer was given permission to use. It is the maximum amount of current allowed to be used. If there is a 50 amp breaker ahead of the receptacle there could be, under certain circumstances, a current of 50 amps applied to the 30 amp receptacle before the circuit opens. This type of installation is contrary to electrical code rules.

### Can you use a 25 amp double pole breaker for a 240 heavy duty whirlpool dryer.?

The recommended breaker for dryers is 30 amps. If you want to do the calculation to see if a 25 amp breaker will work use the following formula. W = A x V, A = W/V. Find the wattage of the unit and divide it by 240 volts to get the amperage. If the amperage is under 25 amps then the breaker will work. If the amperage is over 25 amps then a 30 amp…

### Is it okay to put a 30 amp receptacle on a 50 amp breaker?

No, when an amperage is embossed on a receptacle, that is the manufactures maximum limit that the receptacle will legally handle. A 50 amp breaker should be connected to a wire that is at least rated at 50 amps. The nearest will be #6 rated at 65 amps. By connecting a 30 amp receptacle and presumably a 30 amp load down stream from a 50 amp breaker will not protect the 30 amp device safely…

### Can you switch a 30 amp breaker to a 50 amp?

A wire that would be protected by a 30 Amp breaker would overheat and potentially cause a fire if it were connected to a 50 Amp breaker. If you are changing to a higher amp breaker, you MUST run a new circuit that is appropriate if you want to avoid a house fire. ALWAYS employ a qualified electrician if you are making changes to your electrical system in your home or business.

### Can I use 20 amp receptacle 12 gauge wire and a 15 amp breaker in a circuit?

Yes. The breaker can be smaller, but not larger than the circuit it is protecting. The situation you describe would normally be protected by a 20A breaker, but what you suggest is fine. You couldn't go the other direction and use a 30 A breaker because it wouldn't protect the lesser rated components.

### 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.
