3/0-3/0-3/0-1/0 Copper SER Service Entrance Cable 

Allowable Ampacity at 60° C: 165

Allowable Ampacity at 75° C: 200

Allowable Ampacity at 90° C: 225

Applications:

3/0-3/0-3/0-1/0 Copper SER cable is primarily used as a service entrance cable in residential and light commercial applications. It is typically used to connect the service drop to the meter base and from the meter base to the distribution panelboard.

This cable is rated for 600 volts and is suitable for dry locations, with an operating temperature not exceeding 90°C.

This 3/0-3/0-3/0-1/0 size is commonly used for:

• 200A main service panel feeds in single-family homes, per NEC 310.15(B)(7).
• Subpanel feeds in larger residential properties, such as multi-unit dwellings or apartments.
• Power distribution from meter bases to 200A panelboards in light commercial buildings.
• Feeding HVAC systems, electric furnaces, and large appliances with high electrical loads.
• Backup generator connections where a 200A-rated feeder is required.
