AWG Wire Size Chart

This table provides an overview of American Wire Gauge (AWG) sizes 0000 to 40, including their corresponding diameters in millimeters, cross-sectional areas in square millimeters, and the recommended current carrying capacity for single conductor usage and groups of multi-core conductors in configurations of 2-3, 4-6, and 7 or more. The current capacity values are intended as a general guide and are based on specific conditions such as ambient temperature, type of insulation, and the presence of other conductors.

It's important to note that these figures are approximate and should serve as a starting point for design considerations rather than definitive values. The actual current carrying capacity can vary based on several factors including, but not limited to, environmental conditions, cooling measures in place, and the specific application. For precise and safety-critical applications, consulting the latest National Electrical Code (NEC) standards, or equivalent regulatory guidelines, and possibly conducting empirical testing is strongly recommended.

This table is intended for informational purposes only. Always ensure compliance with all applicable standards and regulations, and consider consulting a professional engineer or electrician for applications involving electrical wiring and current capacities to ensure safety and efficacy.
