Installation and Safety Considerations
✅ Proper Sizing and Connections
- Aluminum cables require a larger diameter than copper cables for the same current capacity.
- Ensure terminals and connectors are rated for aluminum to prevent overheating.
✅ Anti-Corrosion Measures
- Use anti-oxidant compounds to prevent oxidation at connection points.
- Opt for aluminum cables with protective coatings for enhanced durability.
✅ Thermal Expansion Management
- Aluminum expands and contracts more than copper, requiring secure terminations.
- Use compression connectors or spring-loaded terminals to minimize loosening.
✅ Compliance with Electrical Codes
- Follow National Electrical Code (NEC) guidelines for aluminum wiring.
- Ensure proper grounding and bonding to prevent electrical faults.
