A 400 watt heater can safely be used on a 15 amp circuit. The size breaker needed for a circuit is determined by the size of the wiring in that circuit. AWG #14 wire requires a 15 amp breaker. AWG # 12 wire requires a 20 amp breaker.

Electrical power is equal to voltage times current, P = I * V, where P is power, I is current, and V is voltage.

Here, the equation becomes (1500 W) = I * (240 V). I = 1500/240 = 6.25 A

Make sure your electrical system can handle this so that you don't pop a circuit breaker or overheat a wire somewhere.

Watts = Amps x Volts. Amps = Watts/Volts = 4.16. The smallest breaker in a house panel is 15 amps. You will need a 2 pole 15 amp breaker. On a # 14 wire you can load that circuit up to 12 amps.

800 watts/ 240 Volts = 3.34 amps

14AWG wire with a 15 amp will do

To answer this question a voltage needs to be stated. I = W/E, Amps = Watts/Volts.

The equation that you are looking for is Amps = Watts/Volts.

Running on 240 v the heater draws 20 amps so the curcuit breaker should be 25 or 30 amps.

For a 3kW heater, you would typically need a 13 amp fuse. This is calculated by dividing the wattage of the heater by the voltage of your power supply (3,000W รท 230V โ 13A). Always consult the manufacturer's recommendations and a qualified electrician to ensure the proper fuse size for your specific heater.

3 amps

9000 BTU/hour is equivalent to 2300 watts so the heater will draw 10 amps on 230 volts.

6.5 amps

Amperage (coulombs/sec sort of like volume) and wattage (power) are independent of each other if you know the voltage you can calculate amps but they are not the same thing. 3000 watts/X volts=amps ex. 3000 watts/110v=27.28 amps

To answer this question the voltage of the immersion heater is needed. I = W/E.

Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous

To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.

Amperage (coulombs/sec sort of like volume) and wattage (power) are independent of each other if you know the voltage you can calculate amps but they are not the same thing. 3000 watts/X volts=amps ex. 3000 watts/110v=27.28 amps

Heater elements usually have a power factor of 1, but if a load has a power factor of 0.8 it means that the VA is equal to the watts divided by 0.8, so that would be 3750 VA. With 220 v that would draw 17 amps.

The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).

To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 2400 watts / 240 volts = 10 amps. Therefore, the water heater would draw 10 amps of current.

There are zero amps in 3000 volts. A load needs to be connected to the voltage.
