Contamination can accelerate corrosion, especially at cut ends, and compromise electrical performance. Store wire coils in dry, protected areas away from direct sunlight and corrosive chemicals.
• Proper Usage of Tools: Use calibrated, industry-standard tools such as wire strippers, crimpers, and cutters designed for the specific gauge and type of CCS wire. Improvised tools can nick the conductor, damage the cladding, or create uneven terminations, increasing resistance and fire risk. Ensure all connections are secure and properly insulated. Always ground the system during installation to prevent static discharge or accidental energization.
• Consistent Monitoring: Regularly inspect installed CCS wiring for signs of overheating, corrosion, loose connections, or physical damage. Perform continuity and resistance tests post-installation to verify circuit integrity. In critical systems (e.g., telecom towers or grounding grids), schedule periodic maintenance checks to detect degradation early and prevent system failure.
• Avoid Overloading: Never exceed the current-carrying capacity (ampacity) of the wire. Overloading generates excessive heat due to resistive losses, which can melt insulation, cause short circuits, or ignite surrounding materials. Refer to NEC (National Electrical Code) or IEC standards for safe current ratings based on wire gauge, insulation type, and ambient temperature.
