(1)Cord and Fuse Sizes based upon the U.S. National Electric Code and maximum output for 40°C (104°) ambient.
(2)Also called “inverse time” or “thermal/magnetic” circuit breakers; circuit breakers that have a delay in tripping action that decreases as the magnitude of current increases.
(3)Type SD cord or similar in 30°C ambient.
