1. Based on U.S. National electrical Code
2. Also called " inverse time" or "thermal / magnetic" circuit breakers; circuit breakers that have a delay in trip-
ping action that decreases as the magnitude of the current increases
3. Type SO cord or similar in 30° C ambient
4. When operating on these inputs, the line cord should be changed to an input conductor of 6 AWG or larger.
* On 230 Volt / 1 phase inputs the max. rating is at a duty cycle of 30%, except for GTAW processes.
