depends on length of circuit, continuous duty or not. not knowing these factors i would say 12awg on a 20a breaker.
The recommended wire size for a 220 volt circuit according to the 220 volt wire size chart is typically 10 gauge wire for a circuit with a maximum of 30 amps.
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 #10 copper conductor will limit the voltage drop to 3% or less when supplying 21 amps for 150 feet on a 240 volt system.
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.
For a 220 volt circuit at 54 amps, you would need a wire rated for at least 6 AWG (American Wire Gauge) size to handle the current safely. It's always recommended to consult with a licensed electrician or refer to local electrical codes for specific requirements.
For a 100 watt 12 volt lamp, you should use a wire gauge size of at least 18 AWG to ensure it can handle the current without overheating. It's always best to refer to the manufacturer's recommendations for the specific lamp you are using.
For a 20 amp 250 volt circuit, you would typically use a 12-gauge wire. This wire size is rated to safely handle the current and voltage requirements of the circuit without overheating. It is important to always refer to local electrical codes and regulations to ensure compliance.
The sizing of a breaker is dependant upon the size of the wire it protects. The size of the wire is dependant upon what the load current in amps is. Without the amperage and wattage and the voltage of the appliances an answer can not be given. W = A x V, Amps = Watts/ Volts.
AWG #3 copper.
For a 70 amp service at 240 volts, you would typically use a wire size of 4 AWG copper wire. This wire size is suitable for carrying 70 amps of current safely over a 240 volt circuit. Be sure to consult local electrical codes and regulations to ensure compliance with requirements in your area.
The electrical code states that a 7.5 HP 460 volt three phase motor draws 11 amps. For fuse sizes, non time delay - 30 amps, time delay type D - 20 amps and if using a breaker it will be 30 amps. Minimum wire size is #12 and the maximum setting of overload devices will be 13.75 amps
The appropriate wire size for a circuit requiring 60 amps is typically 6-gauge wire.
