The answer depends on several factors: Most electrical codes in the United States are based on the NFPA. Some areas may follow a different standard. Ampacities of conductors are arranged in the NFPA in several charts depending on the installation criteria. In addition the charts have correction factors. The several factors that need to be identified are: What is the conductor made out of: copper, aluminum or other?
Is it in a raceway, on a messenger, in free air, or a cord?
If in a raceway, is there more than 3 current carrying conductors?
Is it high-voltage (above 600) or low voltage?
What type isulation is being used?
What is the allowed voltage drop?
What is the ambient temperature?
As you can see there is no easy answer. However, on a typical installation using copper wire for under 600 volts, the size is in the range of 4/0
What else can I help you with?
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
What size wire should you use for a 20 amp breaker?
For a 20 amp breaker, you should use a wire size of 12 AWG for standard residential wiring. This wire size can safely handle the current load without overheating. Make sure to always consult local electrical codes and regulations for specific requirements.
What size wire should you use for a device operating on 240 VAC pulling 22 amps?
For a device operating on 240 VAC pulling 22 amps, you should use a wire that is at least 12-gauge in size to ensure it can safely handle the current without overheating. It's always a good idea to consult with a licensed electrician to determine the appropriate wire size and type for your specific application.
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 is the Minimum branch circuit wire size in a dwelling?
The minimum size home wiring is #14 AWG, the rating for that size wire is 15 amps.
What size copper wire should you use for 240 volts 200 amps?
3/0 wire 3/0 wire
What is the appropriate wire size for a circuit requiring 60 amps?
The appropriate wire size for a circuit requiring 60 amps is typically 6-gauge wire.
What size circut breaker for 10-2 wire?
A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
What is the appropriate wire size for a circuit that requires 30 amps of current?
The appropriate wire size for a circuit that requires 30 amps of current is typically 10-gauge wire.
What size wire do you need for 15 amps?
AWG 10.
What size wire should you use for a 20 amp breaker?
For a 20 amp breaker, you should use a wire size of 12 AWG for standard residential wiring. This wire size can safely handle the current load without overheating. Make sure to always consult local electrical codes and regulations for specific requirements.
What is the recommended wire size for a circuit carrying 35 amps of current?
The recommended wire size for a circuit carrying 35 amps of current is typically 8 AWG (American Wire Gauge).
What is the recommended wire size for a circuit carrying 80 amps of current?
The recommended wire size for a circuit carrying 80 amps of current is typically 4 AWG (American Wire Gauge).
What is amp size for 14 wire?
