What happens if you put a 30 amp breaker on 14 gauge wire?

Is it safe to have a 14 gauge wire on a circuit protected by a 30 amp breaker? No, 14 gage wire uses a 15 amp breaker. A 30 amp breaker will allow twice the current a 14 gage wire can handle and can overheat the wire - fire hazard.

Does thickness of wire affect current?

You can use it, but you shouldn't because the breaker will not properly protect the wire from overloads.NO! You cannot use any 14 gauge wire on a 20 amp circuit.For a maximum of 30 amps, you'll need a wire gauge of 10. The most common household item that requires a 30 amp circuit is a central air conditioner.Many techs will repeat these rules of thumb and rely on them in all circumstances: “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”No, you can't (and please, don't try). 12 gauge wire is capable of conducting about 20 amps. If you would use 30amp breaker, your wire will get hot long before breaker with cut off the current, what may lead to overheat, melt the isolation and make short circuit (and even fire).14-gauge wire is safe to use when wiring an outlet on a 15 amp or lower circuit. Never use 14-gauge wire for an outlet on a circuit over 15 amps. Check your breaker box to find out the amperage of the circuit your outlet is on.14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps. 10-gauge are used in electric clothes dryers, 240-volt window air conditioners, electric water heaters supporting 30 amps.You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire. To help you understand why this is so dangerous, you need to know what the circuit breaker is for.The 14/2 electrical wire is the best choice for both lights and outlets connected to 15-amp circuits. That being said, it is the safest, most common choice for low-amperage power light fixtures. Keep in mind that the 14-gauge wire is not a good choice for high-amperage circuits.If a wire gauge is “too big” then it is a lot more expensive and is harder to bend, as well as more difficult to attach with wire nuts or to switches.Probably not. The 15-amp breaker protects 14- or 12-gauge wire which the 30-amp breaker would not protect.For commercial on a 15 amp circuit which is what you use 14 awg wire. You can install up to 8 outlets.You can, but it is not a good idea. Highly discouraged. An electrical inspector may have a bird and not want to pass your installation, You will confuse anyone working on the circuit in the future as to if it is a 15 or 20 ampere circuit.Common reasons your breaker keeps tripping include circuit overload, a short circuit, or a ground fault.Maximum Breaker Size is 30 amps. You can use a 20 amp circuit breaker with 12/2 Romex as 12/2 wire is rated for 20 amps. Always remember THE BREAKER IS THERE TO PROTECT THE WIRE NOT THE APPLIANCE !!! You can always oversize the wire , if using a 20 DPST breaker you can use 10/2 if needed...Yes, based on the National Electric Code or NEC, you can use 12-2 AWG cables for THHN or THWN-rated wires. These cables are made for general purposes and can hold up to 194 degrees without taking any damage. It simply means these wires can withstand the heat temperature drawn by a 30 amp circuit breaker.A good rule of thumb is to put a maximum of 16 outlets on a 30 amp circuit.The best wire to use for a 30 amp breaker is a 10-gauge wire.Other Things You Need to Consider When Installing a 30 Amp Circuit Breaker. You must also consider the wire length for your 30-amp circuit, in addition to the wire AWG. A maximum length of 150 feet is allowed when using a 10-gauge wire size.The system has a problem if the total wattage is higher than 30 amps. If you use the devices at the same time, you will cause the circuit to become overloaded. One could make the case that reducing the number of outlets in use lowers the risk of overloading them.No, you can't. The breakers are sized to prevent the total load from drawing too much current through the branch wiring, and starting a fire. Install a larger breaker without upgrading the wiring and you'll burn your house down.Your plug-in appliances will all be designed for those type of receptacles (generally 15A and fit 15A or 20A). GFCI is required for bathroom, but doesn't have to be at the receptacle - could be at the breaker. You can't piggyback 15A or 20A receptacles on a 30A circuit (the heaters). Not allowed.The current will flow more easily through a thick wire than through a thin wire of the same material when connected to the same source. This is due to the fact that the resistance of a wire is inversly proportional to the square of its diameter.
