For a 450' run with a 200 amp service, you will need to use at least 3/0 AWG copper wire for direct burial to ensure minimal voltage drop and to meet electrical code requirements. Always consult with a licensed electrician or local building code authority for specific guidance on wire size and installation requirements for your project.
The conductor can be pulled into conduit and then buried but it is not certified for direct earth burial.
The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
For a 200A service, the recommended copper wire gauge for service entrance cable is typically 2/0 AWG (American Wire Gauge). This wire size is able to handle the ampacity required for a 200A service safely and efficiently. It is always recommended to consult with a licensed electrician to determine the appropriate wire size for your specific installation.
For a 100 amp service, a common feeder wire size would be 2 AWG (American Wire Gauge) copper or 1/0 AWG aluminum. These sizes are appropriate for handling the current capacity needed for a 100 amp electrical service. It is important to consult with a licensed electrician or local building code requirements to ensure the proper wire size for your specific installation.
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 conductor can be pulled into conduit and then buried but it is not certified for direct earth burial.
The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
# 6 copper wire.
For a 200A service, the recommended copper wire gauge for service entrance cable is typically 2/0 AWG (American Wire Gauge). This wire size is able to handle the ampacity required for a 200A service safely and efficiently. It is always recommended to consult with a licensed electrician to determine the appropriate wire size for your specific installation.
Service wire required is AWG # 3/0 copper.
2 copper
Service entrance wire should be AWG #3 copper.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
2AWG.
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
