At 80VA max with 220VAC range I calculate that two SB fuses at approx. 370ma each would be used. We are using 208VAC so the number does not change much.(385 ma) Would 500mA slow blow fuses be used here to provide curve A protection? 1A SB for Curve B? Which would a be better choice, providing my calculations are correct?
