So any size circuit breaker of 20 amps or less will be ok. As a result the amp rating of a circuit breaker has the following relation to the wire size that has been chosen. 12 gauge wire is the next size larger and is allowed to carry up to 20 amps. Is using a 12 gauge wire on a 15 amp circuit a waste of money. Should the circuit breaker fail to operate correctly that heater will draw more current than the wires can safely handle and could heat the wires to the point of melting the insulation around the wires and igniting surrounding materials. Or running a new run back to the panel and putting in a 15 amp breaker will this wire work. This doesn t figure a long continued load that would be 80 of a15 amp circuit 15 x 0 8 12 amps 12 1 1 2 8 outlets if these are receptacles and don t have a specific load lcl doesn t apply. Otherwise you may need fewer appliances using the circuit or you may have a worn out breaker that needs to be replaced with a breaker of the same size. For 12 gauge wire 20 amps can safely be handled. A 20 amp circuit breaker must be wired with 12 gauge wire or larger.
Yes even larger wires than these are possible.
So any size circuit breaker of 20 amps or less will be ok. For example plugging a heater rated for 20 amps into a 15 amp circuit wired with 14 gauge wire poses a distinct danger. If the length of the wire run is long then the voltage drop at the outlets may be excessive with heavy loads. It is rated as able to carry up to 15 amps of current. A 20 amp circuit breaker must be wired with 12 gauge wire or larger. A 20 amp breaker is never allowed to run any circuit whose wires anywhere on the circuit are 14 gauge.
For 12 gauge wire 20 amps can safely be handled. Circuit breakers protect the wires from overheating by limiting the amount of current allowed to pass through them. The minimum wire size for those 15 amp circuits is 14 gauge. If the circuit can perform adequately using 14 gauge wire then you spend money you did not need to but there are some situation where 12 wire is required. Or running a new run back to the panel and putting in a 15 amp breaker will this wire work. It is rated as able to carry up to 15 amps of current. Yes even larger wires than these are possible. A 15 amp circuit could have a maximum of 180 va at 120 volts 180 120 1 1 2 amps. As a result the amp rating of a circuit breaker has the following relation to the wire size that has been chosen. So any size circuit breaker of 20 amps or less will be ok.
If the length of the wire run is long then the voltage drop at the outlets may be excessive with heavy loads. There is the potential for danger anytime a device or appliance tries to draw more power on a circuit than the wire gauge is rated for. A 20 amp breaker is never allowed to run any circuit whose wires anywhere on the circuit are 14 gauge. It is rated as able to carry up to 15 amps of current. A 15 amp circuit could have a maximum of 180 va at 120 volts 180 120 1 1 2 amps. A 20 amp circuit breaker must be wired with 12 gauge wire or larger. 12 gauge wire is the next size larger and is allowed to carry up to 20 amps. Otherwise you may need fewer appliances using the circuit or you may have a worn out breaker that needs to be replaced with a breaker of the same size. Or running a new run back to the panel and putting in a 15 amp breaker will this wire work. Is 12 2 wire ok to use on a 15 amp circuit.
