Frequently asked questions
Is this wire rated for direct burial?
Yes. The 500 MCM Aluminum PV Wire UL4703 is rated for direct burial, conduit, and free-air installation per NEC Article 690 guidelines.
What is the ampacity of 500 MCM aluminum PV wire?
Typically approximately 430 amps at 90°C in free air. Consult NEC Table 310.15 for conduit derating factors based on your specific installation conditions.
Can aluminum PV wire be used for residential solar?
Yes, but 500 MCM is typically specified for commercial or utility-scale installations due to its large current capacity. For residential systems, copper PV wire in 6, 8, 10, or 12 AWG is usually more appropriate.
Does this cable meet NEC requirements?
Yes. The UL4703 listing confirms full compliance with NEC Article 690 requirements for photovoltaic systems.
Do you offer volume pricing?
Yes. Contact our sales team for a customized quote for your solar project.
