I'm working on a project that I need to use switches with ~10 amps DC. Most of the components I run across are rated in AC.
I've seen the conversion of power, meaning power is the same:
120v (AC) * 10A = 1200W therefore,
1200W = 12v (DC) * 100A.
Meaning, what is meant for 120v @ 10A AC will handle 12v @ 100 Amps DC. Which sound ridiculous to me.
I've also seen posted many places that ratings are and should always be LOWER in DC than AC b/c of the current arcing abilities.
So if I'm looking for switches rated in AC ratings. What is the equivalent AC rating to 12v @ 10A DC?
