What is breaker size for 240 volt 9 KW?
The formula you are looking for is I = W/E.
How many miliamp is 1.5 watts at 12 volts?
1000 milliamperes = 1 amp. Assuming a resistive load, amps = watts / volts = .125 amps or 125 milliamperes
What is the capacity in amperes 20 amp circuit breaker supplying a continuous load?
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.
Duplex receptacle circuit given 15 amp breaker 225 amp load?
A 225 amp load will physically not be able to tie into a 15 amp breaker and a duplex receptacle as you can not get a 3/0 wire under the breaker and receptacle terminal screws.
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 size circuit breaker is used for a 10000 watt single phase cooler with 240 volts?
The equation for amperage is Amps = Watts/Volts = 10000/240 = 41.6 amps. It is not stated if this is a motor load or not. If it is a motor load then the feeder has to be rated at 125% x 41.6 = 52 amp wire. Also if it is a motor load then the breaker will have to be 250% x 41.6 = 104 amps. A 100 amp breaker will work and still be within the electrical code ruling. Otherwise for 41.6 amps a 50 amp breaker will be sufficient.
How big of a breaker for a 26 amp motor?
Sizing circuit breakers for motors falls into a different category. Because of the inrush of current when the motor is in the stopped position, the breaker has to be sized to allow for this. Breakers usually are 250% of the nameplate full load amp rating. The wires that feed the motor are sized to 125% of the full load amps of the motor.
What amp breaker for a 220 volt 8000 watt sauna?
A sauna heating element is a resistive load. The equation that you are looking for is Amps = Watts/Volts = 8000/220 = 36 amps. A #8 copper conductor with an insulation rating of 90 degrees C is rated at 55 amps. This will be fed with 40 amp two pole breaker.
What breaker for 17.3 amps?
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.
How many amps can be put on a 125 amp service?
You should not load a 125 amp panel any more than 100 amps.
Is it normal of 50 ampere circuit breaker rating to be hot when load is 17 amps 3 phase at 240volts?
No, the 50 amp breaker should not be getting hot with a 17 amp load. Shut the service off at the disconnect and check the bolts that tighten the breaker to the distribution's bus bars. Check the tightness of the load side of the breaker. if all of these connections are tight then change the breaker out for a new one.
Can you hook up 200 amp dervice to a 125 amp service panel?
No. If device draws 200 amps breaker will trip.
