What classification refers to the cable size in the context of EVSE installations?

The classification that refers to the cable size in the context of Electric Vehicle Supply Equipment (EVSE) installations is the American Wire Gauge (AWG). AWG is a standardized wire gauge system used primarily in North America to denote the diameter of electrical wires. The gauge number indicates the thickness of the wire, with a lower number representing a larger diameter. This system is essential in the electrical industry, especially for applications like EVSE, where proper wire sizing is critical for safety, efficiency, and compliance with electrical codes.

Using AWG helps ensure that the cables can handle the required current without overheating and that the voltage drop over distance is kept within acceptable limits, both of which are crucial in electric vehicle charging scenarios. By selecting the appropriate AWG for the installation, one ensures that the electrical system is robust and reliable for charging electric vehicles effectively.
