Answer for USA, Canada and countries running a 60 Hz supply service.
The wire size and breaker are determined by the amperage on the conductor used to feed the load. Amps = Watts/Volts. 2000/220 = 9 amps. The breaker used to feed this size load will be a two pole 15 amp breaker. A #14 two conductor cable is rated at 15 amps but has to be de-rated by 80% for continuous loads. 15 x .8 = 12 amps. This de-rating is still within the amperage you need to run the heater. There is in the market place now a two wire cable that uses red and black colour coding for electric heating. If you just have a cable with black and white colour coding identify the white wire by wrapping a piece of black tape on both ends around the wire to signify that the cable is used for 220 volts. This keeps the next person that opens the splice safe, as it tells the person that the white wire is not a neutral wire and that the wire is to be consider as a "hot" wire.
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.

When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
What size of breaker to use on a wall unit 220 heater?
The size of the breaker needed for a 220V wall heater depends on the current rating of the heater. Generally, for a 220V heater, a 20-amp breaker is common. However, it's important to check the manufacturer's specifications and local electrical codes for the appropriate breaker size.
Can I you use existing 8 3 wire hooked to a 30amp breaker was hooked to old electric heater to wire a heater that requires 10 2 wire its a 5000watt 240volt heater?
No, you cannot use an existing 8 3 wire hooked to a 30amp breaker for a heater that requires 10 2 wire. The wire gauge and breaker size need to match the specific requirements of the new heater to ensure safety and proper function. You will need to upgrade the wiring to accommodate the 10 2 wire needed for the 5000-watt 240-volt heater.
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.
What size breaker needs to be installed for 15000 watt 240 volt heater?
A 15000 watt 240 volt heater would require a 62.5 amp circuit breaker. To accommodate this exact load, you would typically use the next standard breaker size above 62.5 amps, which is a 70 amp breaker to ensure safety and proper operation of the heater.
What is the appropriate water heater breaker size according to the water heater breaker size chart?
The appropriate water heater breaker size is determined by the water heater's wattage and voltage, as indicated in the water heater breaker size chart. It is important to match the breaker size to the specifications of the water heater to ensure safe and efficient operation.
What size ext cord for 2000w heater?
Use #12 wire and a 20 amp two-pole circuit breaker.

What is the recommended range breaker size for a circuit breaker in a residential electrical panel?
The recommended range breaker size for a circuit breaker in a residential electrical panel is typically between 15 to 20 amps.
Can I you use existing 8 3 wire hooked to a 30amp breaker was hooked to old electric heater to wire a heater that requires 10 2 wire its a 5000watt 240volt heater?
No, you cannot use an existing 8 3 wire hooked to a 30amp breaker for a heater that requires 10 2 wire.

What is the appropriate size of a breaker needed for a 240-volt circuit that requires a 50 amp breaker?
For a 240-volt circuit that requires a 50 amp breaker, the appropriate size of the breaker needed is 50 amps.
What size breaker and wire for 2000 watt heater?

How are Branch circuit protected?
Branch circuits are protected by the circuit breaker found in the electrical panel. Each circuit should have its one breaker. The breaker should be rated to protect the insulation of the wire, so you can determine the breaker size based on the circuit conductor size Example #14-2 should be protected by a 15 amp breaker
What size breaker needs to be installed for 15000 watt 240 volt heater?
A 15000 watt 240 volt heater would require a 62.5 amp circuit breaker. To accommodate this exact load, you would typically use the next standard breaker size above 62.5 amps, which is a 70 amp breaker to ensure safety and proper operation of the heater.
What size amp circuit breaker should be used for a hot water tank?
Assuming you are referring to a 240 volt residential hot water heater you will need to install 10/2 NM cable (Romex) with ground from the service panel to the water heater wired to a 30 amp circuit breaker in the service panel. If you cannot see the water heater from the service panel you will need to install a service disconnect at the water heater.
What is the standard to select circuit breaker?
Add up your amps to calculate your breaker size. Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.
