Overhead Distribution Copper Cable Service Drop

Copper service drop cable may be specified when the project requires higher conductivity, compatibility with copper service equipment, reduced conductor diameter, or a utility-approved copper conductor for the overhead service connection.

Conductor material affects current capacity, cable weight, connection requirements, voltage drop, and long-term compatibility with terminals or service equipment. Copper and aluminum service drop cables should not be treated as direct one-for-one substitutions without checking the full project requirements.

Important conditions include span length, exposure to weather, service load, point of attachment, clearance requirements, conductor configuration, and the equipment or utility standard that governs the service connection.

Yes, copper service drop cable may be used for replacement service work when it matches the existing system requirements, utility rules, service rating, and connection equipment. The replacement cable should be selected based on the full service design, not only the previous cable size.

Buyers should provide the service type, conductor size, number of conductors, voltage rating, span details, required length, utility specification if available, and whether the cable is for a new overhead service, replacement service, or project-specific distribution connection.
