Calculating the right ampacity is critical to safety: A wire gauge that is too small for the electrical load may lead to overheating, which could melt the wire insulation and start an electrical fire.

Using the UL requirements and the National Electric Code, we’ve created this Contact Ampacity chart to ensure your amperage is always at the correct level. Not sure which ampacity is right for you?
