How much current does a 1/0 AAAC wire carry?

The current-carrying capacity, or ampacity, of a 1/0 AAAC (All Aluminum Alloy Conductor) wire is approximately 226 amps under specific conditions, such as a standard temperature and permissible ambient conditions. Ampacity can vary based on several factors, including the installation environment (like conduit or open air), ambient temperature, and whether the wire is in a bundle with other conductors.

In typical applications, the rated capacity allows for optimal performance in terms of safety and efficiency. This means that a 1/0 AAAC wire can handle a maximum of 226 amps without exceeding the thermal limits that could lead to damage or failure of the wire insulation. Understanding ampacity is crucial for linemen and electricians when designing and installing electrical systems to ensure that the conductors can safely handle the expected loads.
