Best Answer

A 2000 watt heater draws 8.3 amps on a 240 v supply, so the cutout should be set to 10 or 12 amps.

In North America a 2000 watt baseboard heater will be fed with a two pole 15 amp breaker. A two wire cable of #14 copper will be used to connect the supply voltage to the heater.

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

A 50 watt heater is major over kill for a 3 gallon tank, a 10 watt heater is more than enough for a tank that size. You will nuke your aquarium very quickly the first time the 50 watt heater sticks on, with a 10 watt heater if it sticks on the aquarium temp will only raise a degree or two.
