Buying advice

When choosing aluminum wire, consider the application’s current rating, environment (corrosion risk), and required insulation type. Verify that the wire’s ampacity matches the circuit load and that the insulation is rated for the temperature and exposure conditions of the installation. Pay attention to the conductor’s coating to mitigate oxidation and ensure proper grounding methods are used, as aluminum can be more prone to corrosion at connections.
