US NEC: 4800 watts is 40 amps at 120 volts, or 20 amps at 240 volts. This can be no more than 80% of the breaker's rated value. You need a 50 amp breaker for 120 volt operation, though 120 volt operation is not advised. You need a 30 amp breaker for 240 volt operation.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 10y agoOn 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.

What size wire and breaker do you need for a 5000 watt garage 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
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.

How many amps needed for a 3000 watt 240 volt base board heater?
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.
What size of circuit breakers needed to run two 1500 watt heaters in parallel that are 240 volts?
I = W/E. 1500/240 = 6 amps for each heater. In parallel the total connected load will be 12 amps. A #14 conductor is rated at 15 amps and de rated to 80% can carry 12 amps continuous. The breaker needed for this would be a two pole 15 amp breaker. If this is a new installation I would use a #12 conductor for the two heaters on a two pole 20 amp breaker. The conductors will run much cooler using a larger size.
How many amps breaker you need for a 5000 watts immersion heater?
To answer this question the voltage of the immersion heater is needed. I = W/E.

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

What size breakers are needed for two 500 watt baseboards?
Each baseboard heater will draw a little over 4 amps at 120 volts or 2 Amps at 240 volts. The total number of baseboards on a circuit will draw the sum of these amps. Keep the load under 80% of the amperage rating of the breaker.
What's a double breaker 20 amps and 30 amps?
A double breaker is a breaker that has 2 switches on it. One of the switches is 20 amps and the other is 30 amps.
What size breaker and wire for 2000 watt heater?
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.
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.
Can a 4800 watt water heater run on a double pole 15 amp breaker?
Current in amps = watts/ voltage in volts. If you have a 240 volt supply, it will draw 4800/240 = 20 amps, so no. This is a very powerful water heater, and would normally be wired into a dedicated circuit, presumably with a 30 amp breaker.
