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.
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.
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.
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.
If the heater has a specified branch circuit rating with the manufacturer's information then follow that. If not then assuming it is to be run more than 3 hours per day: 19.7 A x 1.25 = 24.6 A Next size standard breaker is 25 A (see NEC 240.6) So you will need #10 AWG Copper and a 25A 2 pole breaker.
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.
Use #12 wire and a 20 amp two-pole circuit breaker.
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.

The recommended range breaker size for a circuit breaker in a residential electrical panel is typically between 15 to 20 amps.
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.
For a 240-volt circuit that requires a 50 amp breaker, the appropriate size of the breaker needed is 50 amps.
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
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.
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.
If the heater has a specified branch circuit rating with the manufacturer's information then follow that. If not then assuming it is to be run more than 3 hours per day: 19.7 A x 1.25 = 24.6 A Next size standard breaker is 25 A (see NEC 240.6) So you will need #10 AWG Copper and a 25A 2 pole breaker.
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
