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

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.


How do you wire a electric garage heater drawing 5000 watts 240 volts to a30 amps circuit?

To wire a 5000 watt, 240 volt electric garage heater to a 30 amp circuit, you'll need to use 10-gauge wire. Connect the black and red wires to the corresponding hot terminals, the white wire to the neutral terminal, and the green or bare wire to the ground terminal on the heater. Make sure to install a 30 amp double-pole breaker in the electrical panel to complete the circuit.


What size breaker box do you need for a garage?

The size of the breaker box needed for a garage will depend on the electrical demand of the devices and equipment used in the garage. It is recommended to consult with a licensed electrician to determine the appropriate size and capacity of the breaker box based on the specific requirements of the garage.


What size breaker for 120 volt 2500 watt water heater?

For a 2500 watt water heater operating at 120 volts, you would need a 20 amp breaker. This ensures the breaker can handle the load without tripping.


What size breaker for a 1500 watt 120 volt heater?

To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.

Do you need a main disconnect on the feeder wires running to a detached garage running from the box in the house?

Yes you do. The detached garage will either be fed with a single circuit or a sub panel. The wire feeding the garage will need to be protected and that is the purpose of the breaker (disconnect). The breaker size will be determined by the size of the wire that is used on this circuit.

What is the breaker size for a 10 KVA electric heater?

The breaker size for a 10 KVA electric heater would depend on the voltage it operates at. For example, for a 240V heater, you would need a 41.67 Amp breaker (10,000 VA / 240V = 41.67 A). It is important to consult with a licensed electrician to ensure the correct breaker size and electrical setup for your specific heater.

What amperage breaker to run 500 watt 240 volt heater?

To run a 500 watt 240 volt heater, you would need a 2.08 amp breaker. This can be calculated by dividing the wattage by the voltage (500W / 240V = 2.08A). You would typically round up to the nearest standard breaker size, which in this case would be a 3 amp breaker.
