Yes, 25 amp circuit breakers are available, though they are less common than standard sizes like 15, 20, or 30 amps. These breakers can be used in specific applications where a 25 amp capacity is required, such as certain types of electrical equipment or circuits. It's important to ensure compatibility with your electrical system and to follow local electrical codes when selecting and installing circuit breakers.
You have to rewire the circuit completely with 10 AWG wire and replace all outlets and switches with devices rated at 25 Amps. Note 25 Amp breaker is an unusual size. 10 AWG will go up to 30 amps, and that would be the way to go.
A 15a circuit can supply approximately 1650 watts, so 1650/65=25. I would stop at 20.
I would suggest a 20 amp breaker. * Added - I would suggest a 25 amp breaker. A slight surge, depending upon what equipment is the source of the 17.3 amp load, should not result in circuit breaker opening. <<>> In North America, the electrical code only allows circuit loading up to 80% on a continuous load. A 20 amp breaker can be legally loaded to 16 amps. A 25 amp breaker can be legally loaded to 20 amps.
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
For a 25 amp circuit, the appropriate wire size is typically 10 gauge wire.
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
30 amp wired with AWG # 10 wire.
If the wire used on the circuit is sized for 15 amps (usually 14 gauge) you run a very serious risk of fire.If the wire used on the circuit is sized for 25 amps (usually 10 gauge, good for 30 amps) there is no increased danger.Additional InformationIf you don't know if the wire is sized for 25 amps, DON'T DO IT!A 25 amp circuit would require 10 AWG wire. The fire hazard mentioned above is real and you shouldn't ignore that advice.
You have to rewire the circuit completely with 10 AWG wire and replace all outlets and switches with devices rated at 25 Amps. Note 25 Amp breaker is an unusual size. 10 AWG will go up to 30 amps, and that would be the way to go.
Install the fuse that is required for the circuit.
Yes, it will be protected by a circuit breaker or fuse. The normal rating of the circuit breaker or fuse is 25% more than the maximum current expected, or the maximum current allowed for the cable size, whichever is lower.
You could, but it is not recommended. Overloading a circuit can start a fire.
For a continuous load the circuit breaker is set 25% higher than the load current. So a 20-amp breaker is used with a continuous 16-amp load.
Using a 25 amp fuse in a slot rated for 20 amps is not recommended. The higher amperage of the 25 amp fuse can allow excess current to flow through the circuit, potentially leading to overheating, damage to wiring, or even fire hazards. It's best to use a fuse that matches the rated amperage of the circuit to ensure safety and proper functioning.
Fuses and circuit breakers are rated differently as applied to electrical loads. A motor load of 12 amps would require a fuse rating of 21 amps ( 12 X 1.75=21) or the next standard size of 25. A breaker for the same load of 12 amps would be a 30. (12 x 2.50=30) However if your circuit is number 10 copper wire and supplies 30 amp rated receptacles, you would be perfectly safe in using the fuses.
Check to ensure the connections are tight at the breaker box and the disconnect boxes. It could be that you simply have a loose connection. I have seen this occur from time to time and you may have answered your own question.When the temperature rises the breakers also heat up because of this,especially if the breaker panel is in the sun all day.If the breakers have some age on them try replacing them and checking the amp draw.
