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.
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.
The current is 500/110 amps and you add 25% so the answer is 6 amps.
15 amps
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.
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
To answer this question the voltage of the immersion heater is needed. I = W/E.

You need 12.5 Amps. For a continuous load you want to only have 80% of the current which would be 12 Amps. Best to go with a 20 Amp breaker.
It should be on a 20 amp breaker.
800 watts/ 240 Volts = 3.34 amps 14AWG wire with a 15 amp will do
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.
Running on 240 v the heater draws 20 amps so the curcuit breaker should be 25 or 30 amps.
12.5 Amps Take your 1500 watts dvided by your 120 volts to get your amps
