AC Input Fusing
below provides output ampere ratings for the Diode Bus Supply
(including continuous, 1 minute, and 3 seconds) and recommended AC line
input fusing information. The short circuit protection fuses are acceptable
for UL and IEC requirements. Sizes listed are recommended sizes based on
40 °C (104 °F) and the U.S. NEC. Other country, state or local codes may
require different ratings.
