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.
On a 240 v supply the heater takes 22.5 amps so a 30-amp breaker is OK. On different voltages the current would be different.
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
Running on 240 v the heater draws 20 amps so the curcuit breaker should be 25 or 30 amps.
The equation that you are looking for is Amps = Watts/Volts.

To answer this question the voltage of the immersion heater is needed. I = W/E.
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.
It should be on a 20 amp breaker.

Running on 240 v the heater draws 20 amps so the curcuit breaker should be 25 or 30 amps.
The equation that you are looking for is Amps = Watts/Volts.
Depends on your supply voltage. I = P/V. Find out your supply voltage and divide it into 1500. This will give you your heater's current draw in amps.
The equation that you are looking for is I = W/E. Amps = Watts / Volts.
A 15 amp breaker will trip at 15 amps at an ambient temperature of 40 degree C. If the ambient temperature is higher the breaker will trip before 15 amps and if the ambient temperature is lower the breaker will trip after 15 amps.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
