(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 SJ cord or similar in 30°C ambient.
