In studying for NABCEP certification I am a little confused about whether you multiply the short circuit current by 1.25 once or twice (1.56) in order to calculate maximum circuit current in determining wire size. Same for overcurrent protection.
I have always done it twice (1.56) for both PV source circuit and PV output circuit. Once for over irradiance and once for continuous use. But a handout at a recent seminar that I went to totally confused me. Can anyone spell it out very clearly? Thank you.
