CCS and Copper for Grounding Conductors
Compare the required fault duty, conductor resistance, installation load and exposure conditions. For CCS, include the steel core, copper layer and connection design; for copper, define the grade and conductor construction. Use the project requirements to compare complete grounding paths.

| Decision | Copper Clad Steel (CCS) | Pure Copper | Acceptance basis | Your input or result |
|---|---|---|---|---|
| Construction | Steel core with copper cladding | Copper grade through the conductor section | Specify wire or strand construction and condition. | |
| Electrical duty | Resistance and fault response depend on grade, section and complete construction | Resistance and fault response depend on grade, section and complete construction | Use the same fault current/duration and grounding design. | |
| Mechanical and corrosion | Core, copper coverage, cut ends and joints affect installed behavior | Copper section, joints and exposure affect installed behavior | Specify installation loads, medium and test basis; no universal service life is assumed. | |
| Connection | Hardware and process must fit CCS construction | Hardware and process must fit copper construction | Check the installed connection and project-permitted materials. |
