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.
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.
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.
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
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.
AWG #3 copper.
The number of automotive amps a 30-foot strand of copper wire can carry depends on the gauge (thickness) of the wire. For example, a 30-foot strand of 10-gauge copper wire can typically carry up to 40-50 amps for automotive use, while a 30-foot strand of 12-gauge wire might be limited to around 25-30 amps. It's important to consult wire ampacity tables and consider factors like temperature and voltage drop to ensure safe and effective performance.
The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?
A #4 copper or #3 aluminium conductor will limit the voltage drop to 3% or less when supplying 30 amps for 150 feet on a 120 volt system.
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.
