For Service Entrance Cable 600 kcmill (Thousands of circular mils).
250 MCM aluminum minimum
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 150 amps for 150 feet on a 240 volt system. This size will allow the conductor to be loaded to 120 amps. 150 x 80% = 120 Conductors are only allowed to be loaded to 80% or their rated capacity. If you need the full 150 amps then you would need to use a wire with a rating of 190 amps. 190 x 80% = 152 amps A 4/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 190 amps for 150 feet on a 240 volt system.
A #3 copper wire with an insulation factor of 75 and 90 degrees C is rated at 100 and 105 amps respectively.
For a 3200 amp service, the appropriate wire size will depend on several factors, including the type of wire (copper or aluminum), insulation type, and installation conditions (such as ambient temperature and conduit use). Generally, for copper wire, you would typically use 2500 kcmil or larger, while for aluminum wire, you might use around 3500 kcmil or larger. It's crucial to consult the National Electrical Code (NEC) and a qualified electrician to ensure compliance with local codes and safety standards.
The recommended wire size for a 100 amp aluminum service is typically 2 AWG (American Wire Gauge).
The recommended aluminum wire size for a 200 amp service is typically 2/0 AWG.
The recommended wire size for a 200 amp service using aluminum wire is typically 2/0 AWG (American Wire Gauge).
For a 100 amp service, it is recommended to use aluminum wire that is at least 2 AWG in size.
For a 200 amp service, a minimum of 2/0 gauge aluminum wire should be used.
The recommended wire size for a 100A service is typically 2 AWG copper or 1/0 AWG aluminum.
The recommended service wire size for a residential electrical service upgrade is typically 2/0 copper or 4/0 aluminum.
250 MCM aluminum minimum
For a 200 amp service, it is recommended to use aluminum wire that is at least 4/0 gauge in size to ensure proper conductivity and safety.
A 100 amp service requires that you use AWG 4 copper wire or AWG 2 aluminum wire.
For a 100-amp service, you will typically need a wire size of 2/0 or 3/0 copper or 4/0 aluminum. It is recommended to consult with a licensed electrician to determine the exact wire size needed for your specific installation.
The recommended conduit size for 4/0 aluminum wire is 2 inches.
