What is breaker size for 240 volt 9 KW?
The formula you are looking for is I = W/E.
What size breaker is required for a 13.8 kw electric heater 3 phase 208 volts?
For a 13.8 kW electric heater at 208 volts, you would need a 3-phase circuit with a minimum of a 50-amp breaker to handle the load safely. This calculation is done by dividing the power (13,800 watts) by the voltage (208 volts) and then dividing by the square root of 3 (since it's a 3-phase system).
How much current would a 5-kW heater draw with 230 volts?
The formula you are looking for is I = W/E, Amps = Watts/Volts. Amps = 5000/230 =21.7 amps. The wire size to run this heater would be a #10 copper conductor. The supply breaker would be a two pole 30 amp breaker.
What size of wire and breaker for a 25Kw Furnace?
For a 25 kW furnace, you typically need a 100 amp double-pole circuit breaker. The appropriate wire size would generally be 3 AWG copper or 1 AWG aluminum, depending on the length of the run and local electrical codes. Always consult with a licensed electrician to ensure compliance with local regulations and to confirm the specifications based on your specific installation conditions.
What should a 3 kW immersion heater circuit must be provided with?
A 3 kW immersion heater circuit should be provided with a dedicated 15 Amp circuit that is protected by a 15 Amp circuit breaker and wired with appropriately sized cables (typically 14 AWG for residential wiring in the US). Additionally, a Ground Fault Circuit Interrupter (GFCI) protection may be required for safety.
What is breaker size for 62.19 KW 3 phase?
A breaker protects the wire size of the feeder that is connected to it. The amperage of the load must be found. Without a voltage stated the amperage from the wattage given can not be calculated. The equation for amperage when the kw is given is A = kW x 1000/1.73 x volts x pf. The pf constant to use is .9.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.
What is breaker size for 240 volt 9 KW?
The formula you are looking for is I = W/E.
What the breaker size require for kW?
The use of a breaker in a circuit is to protect the wire size used in the circuit from becoming overloaded. Using the wattage of the load does not help for breaker sizing because the breaker operates on amperage. Amperage can be found from wattage by using the following equation. I = W /E. Amps = Watts / Volts. As you can see the amperage can not be calculated because there is no voltage stated.

Can you run a 2 kw convector heater through a 25 amp trip switch at 240 volts?
Yes, the total amperage load of a 2000 watt heater at 240 volts is 8.3 amps. Keep in mind that the wire feeding the heater must be a #10 because the breaker is rated at 25 amps. A wire's ampacity rating can be larger that the breaker amperage rating but never smaller. Example, a #14 rated at 15 amps or a #12 rated at 20 amps can not be connected to a 25 amp breaker. The 25 amp breaker does not trip until it reaches 25 amps well over the allowable amperage of the #14 amd #12 wire. This is why a #10 wire must be used as its rating is 30 amps.
Is a 60 amp breaker correct for a 10 kw 220 heat strip?
10 kW at 220v will use 45.45 Amps. I'd recommend a 60A circuit, with a 60A breaker, but the heater or electric furnace should have "maximum fuse amps" rated on its nameplate. Above all, neverconnect wiring to a breaker that is rated higher than the maximum current capacity of the wire. In the case of 60A, use #6 AWG wire.The HVAC Veteran

Size of wire need for 3 KW turbine for transmission?
To answer this question the voltage of the system is needed.
How do you size a circuit breaker for a 75 kW generator?
To answer this question the output voltage of the generator must be stated. Breakers are sized to protect the wire that is connected to it. Wire is sized by the amperage that it can carry. Once the voltage is stated use the following equation Amps = kW x 1000/1.73 x Volts x pf. for three phase and Amps = kW x 1000/Volts x pf. In both cases use .9 for a power factor value.
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
